Two to three years is the average lifespan of a domesticated betta fish. However, up to 6 years is very achievable and 10 has been done! You just need to make sure you can give your betta fish the best environment possible.

It’s this blog’s aim to make that 10-year achievement possible for you and your betta.

Secret Betta Tip: Bettas are often adults when sold at pet stores. Ask how old the fish is to ensure you have your fish for the longest time possible or even get a very young betta from a breeder instead.

This video below has some really great information about spotting old age in your betta fish and how to care for them to help them live longer.

Keeping Your Betta Fish Healthy and Happy

You will often see these colorful little fish in small containers at the pet store. They are sold this way because they can’t be kept together in one large betta tank as the males will fight each other. These small tanks are not suitable living spaces for betta fish; betta fish ideally need around 5 gallons of personal space in their tank. We have a page all about the best tanks for betta fish here.

If you decide to “save” one of these betta fish from their tiny prison, then you will need to buy your own betta tank, as well as betta fish food, betta fish plants and other accessories for your new pet. Check out the tools all betta fish owners need.

As mentioned before ideally your betta tank will be at least 5 gallons, 1.5 – 2 gallon tanks have done the job for many owners but we feel 5 is the magic minimum number for the healthiest and happiest betta fish.

Betta specific fish food is great as it has taken into account the natural diet of the fish and has been produced to match (or close enough) the fish’s natural requirements.

A few live aquarium plants can provide a great retreat for your betta. It can also provide shade to help avoid algae growing so fast and can also help naturally filter out some impurities and nitrogen that will build up in the tank.

We have some information on the natural habitat of bettas and how your tank can be set up to replicate this on the homepage.

Betta Fish Life Span

So, how long do betta fish live?

If raised under optimal conditions, the betta fish can live to approximately six years, but in most cases a domesticated Betta fish will only live about half that time. This is because of the nutrition and living conditions are not always perfect.

One advantage of having a betta as a pet is that it can be kept in a relatively small tank. The flip side to this is that the natural waste from the fish contaminates the water in the betta tank faster. Be sure to clean your tank out regularly – every week you should be removing 10 – 15% of your water and replacing it with fresh conditioned water.

Betta Tip: The female betta fish will usually live a bit longer by a few months than a male betta fish. However, most people prefer males because they are much more colorful and have longer and fancier fins.

Fun Fact: One way to determine how long your pet betta will live is by knowing its age. Read our article to learn how to do this. Proceed here — How Old Is My Betta Fish: 6 Markers Determining Species Age.

Help Your Betta Live Longer

If you want your betta fish to live as long as possible, then be sure to feed it with betta fish food like brine shrimp, blood worms, and specially marked food for bettas. Create your plan in advance for feeding betta when going on vacation.

Fighting fish have a tendency to be picky about their food, quite often general tropical fish food just won’t cut it and they will not eat it (look like divas and act like divas). But remember, overfeeding your betta can be just as bad as underfeeding, a few pellets once a day (or half the amount and give once in the morning once at night) will be just fine – once a week you can leave a day out, this helps to reduce the risk of constipation.

Another factor for how long a betta fish will live is the water temperature in the aquarium. Be sure to keep the water at between 75 and 79 degrees Fahrenheit. Choose and research a good aquarium heater and get a reliable tank thermometer to keep track of the temperature. A 25-watt heater will do the trick!

Although we strongly disapprove of it… if you do choose to keep your betta in a small tank it is probably best not to use a heater at all. A tank heater in a small tank can lead to the water temperature rising very rapidly, which is not good for the fighting fish – it can be almost like cooking them. If you do choose to keep your betta in a small tank, try and locate it in a warm place in your home.

All in all, take care of your betta fish and you will get the enjoyment of its company for several years to come.

  1. Does anyone know why my Japanense Male Fighting fish would have what looks like an eye thats bulging. Was’nt like that a day or two ago.

    1. Ooh that doesnt sound good 🙁 It sounds like a common disease called Popeye – this is usually caused from dirty water!
      Not many other Bloggers do this but here is a page from an external blog which has a great page on diseases, symptoms and cures. Betta Talk Disease Page Hope this helps! 🙂

  2. ok well my brother suprised me with a japanese fighting fish and i really dont know how to take care of it its name is angelo haha but im only 13 any tips on what type of tank and how the water needs to be im scared to buy a tank with a heater i was thinking of buying a plastic one… please reply 😀

    1. Hi Loren. You should use treated tap water in your tank and the water ideally should be in the high 70s degrees Fahrenheit. You should not use distilled water as this has been purified to a level that there are no minerals left.

      The happiest and healthiest Bettas live in a tank with a filter and a heater and have 5 gallons of space. They can live in less space though. A filter is not necessary but without one you will need to clean your tank more often.

      Hope this helps! 🙂

      1. I just got my betta fish, renegade blueberry a week ago and the lady(who has 2 at home) told me to use this treatment every time i put fresh water from the tap into my tank. Does this really work or will it take out minerals needed for my fish to live a long and happy life? The bottle did say it was for bettas but i have my doubts

        1. Water treatment should be a great addition! Especially if you follow the instructions and its even better that yours is made just for Bettas.

          It is when people boil tap water when it becomes a problem with loss of minerals. Boiling the water removes all the minerals this should never be used it your betta fish tank, treatment is recommended.

        2. I just use a regular small plastic tank no heater but use Luke warm water and feed it fish food they really don’t need that much caring and can go up to a week or so being unfed also I don’t use anything to take out minerals or anything like that from the water my Beta is perfectly fine and I’ve had it for 1 year

      2. Hi! I have had my beta fish, Chrome, almost 4 years he seems to be super happy based on my limited knowledge. He is an A filtrated tank with plants and A Japanese temple to hide in! I found that he loves to look in the mirror as well as follow my shiny jewelry ring around I just want to make sure that I am NOT playing with him too much or over stressing him are there any rules or guidelines to how much attention I should give him per day meaning I will sit in front of the tank for about five minutes a few times every day and allow him to follow my ring times I will even put a shiny spoon on the outside that he can follow. He seems to enjoy it as he goes to the top of the tank and blows a couple of bubbles. But once again not sure if this is good or bad please let me know if you have any suggestions

        1. Sounds like you are having lots of fun with your fish! 🙂
          If he is flaring at his reflection in your ring just be careful you are not stressing him out too much. He may think it is another male in with him.

  3. My Japanese fighting fish is approximately 4.5 to 5 years old. Just recently is has stopped moving around as much and lays on the bottom of the fish bowl for long periods. Is this normal? Is there anything I can do?

    1. 4.5 – 5 years! That’s a brilliant age! Well done for that. You must take great care of him. Bettas can quite often have slow periods where they just chill. It can sometimes be a sign of over feeding or constipation?

        1. My Betta was 13 when it started doing that. He had the gray scales, I assumed sign of him beig old, he died a week later.

    2. My betta fish is blue and he is about 6 years old and he looks great he is actually more active and has a brighter color than when I bought him so he definitely isn’t getting old! I got him when he was very young, but I forgot what type of betta he is.

  4. Hey, I bought a Betta fish three years ago at Petco and the little guy seems to be very depressed. I know it’s possible for these fish to get sad, but I’m not sure how to fix that. I tried many things to get his confidence up, but nothing seemed to work… Please help, thank you.

    1. There are many reasons why your betta may seem depressed. Betta fish quite often have a chill out day or two, so make sure it isn’t just one of those and you are worrying over nothing. Clean water and plenty of space to swim are some of the main reasons he may become depressed. Have you changed anything in his tank? Sometimes it takes the a few days to get used to changes. And what about reflections or other betta fish in sight? It may become stressed if it sees its reflection or other bettas on a constant basis, as it will see it as a threat! Hope this helps, and sorry about any spelling errors, I sent it from my iPhone. 🙂

  5. Wow, great post. I have 2 betta fish both males (don’t worry, not in the same tank). It’s my first time having a fish in the family. I don’t know how long they are gonna last, but they look pretty healthy to me.
    I use mineral water for both of my fish, and sometimes when I am not able to buy (because the store is a bit far away, and it’s very heavy to carry a jug.. I’m a girl =_=) I use boiled water for it. I put in salt occasionally (I have been researching) because I heard that salt is a good prevention for parasites… not that there are any.. I don’t think there will ever be any. I don’t use a heater, my tank is only a 2 gallon tank. I don’t think I should use a heater since I live in a tropical country xD Does that count? Well, since you said that heaters aren’t good for small tank, I guess it’s fine.

    1. Hi, no you wont need a heater if you are living in a tropical country, the temperature should be fine 🙂 .

      Hmm… I don’t know what the tap water conditions are like in your country but boiling tap water and using it is not good for the fish’s health. By boiling the water you remove all the impurities, but there are some minerals in those impurities that the fish need. You would be best using tap water that you have conditioned with some aquarium water conditioner.

  7. I’m on holidays at the moment but have a fighter fish at home that my cousin hasvbeen looking after for me. I’ve had him just over a year n have just been told from my cousin while I’ve been away 🙁 I do have another one that I’ve had for a few months, any tips u can give me so I can try n get this one to live longer. They were both in small tanks, bought from the pet shop that came with food and water conditioner. They don’t have lids tho so I’m wondering whether the dust from the room might’ve made the other one sick?? Any insight would be much appreciated!

    1. 🙁 sad for your loss!

      If you are only using a small tank the best thing you could do to improve a betta’s health and happiness is to keep them in a bigger tank. A tank with a filter to allow for better water conditions longer and also a heater to keep the water at a steady 79degF.

    2. Sorry for you loss! :'( well if you want your betta to live longer i suggest that you keep the water that he is in about 70 to 80 degrees. I also recommend that you get lids for the betta tanks, just to keep all the dust and particles out of the water. Make sure you feed your betta about 2 pellets of food in the morning, and 2 pellets of food at night. clean your beta’s tank about every 2 weeks also, get a bigger tank! you need about 5 gallons for your betta to like a long happy life!


      1. I had my beta fish for 13 years and he was just in a small glass vase with the plant on top of the opening. Never conditioned the water. I did feed him everyday in the morning, I talked to him and played with him. Maybe affection is what they really need.

  8. Hey Guys! well I have a male betta fish..and his name is gilly. I just have 2 question’s for you guys? ok well my betta fish’s water is mostly ALWAYS clean it’s a 5 gallon tank.. I clean it about every 2 weeks I put water conditioner in there and everything. So my first question is, when I clean the tank and the rocks, and the plant, now when i put the water in there is like these little things that fly around in the water, not much just a little..will they hurt him or make him sick? my 2nd question is gilly (my betta) usually isn’t very active unless you are not like in the room or around him..why is that? PLEASE COMMET YOU ANSWERS! THANKS!(:

  9. Hi All,

    I don’t have a betta fish. However, my friend does. I am quite concerned because it is her second one and they are only lasting about 3-4 months. I have my reasons as to why it might be the case but I am not sure.
    Overfeeding may be a possibility, they also have two cats and it is in a small tank (probably the size of a small gift box. A main concern is that one of the owners smokes and not the legal stuff…..could that be the killing cause?

    Would love some feedback. I just want to show my best friend that there is a reason and it can be prevented.


    1. Hi Gem,

      Thanks for your concern. Yes well looked after betta fish can live much longer. Overfeeding is definitely a problem, a betta fish’s stomach is tiny, about the size of its eye, two or three pellets per meal is sufficient. Any left over food will pollute the water and create dirty water – which in a small tank like you say can quickly become a problem! Small tanks like that will need very regular water changes, which is a pity as they stress the betta fish.

      (Not too sure about the smoking though, we’ll stay out of that conversation)

    2. I am sorry to hear this, as I have the exact same problem! I don’t really have a lot of advice other than try to carefully talk to your friend about why they are dying. Best wishes on sorting out this problem. Good luck!

    1. Do you mean one day old to yourself? Or you have got a tiny baby fry that is one day old? I am guessing you mean that he is a day old to yourself as petstore do not sell one day old betta fish.

      A betta fish’s stomach is about the size of its eye, it is important not to over feed your betta. Two or three pellets will be fine per feed 🙂

  10. Hi, Im the proud owner of a silver reddy crown tail (what i was told any way) Betta. He lives in a 3 foot by 1 and a half foot by 2 foot tank, Has about 10 plants (just basic oxy weed) and a few rocks with a silocon sand base. Water filter and a heat stick set to about 27 degress (round 76 farin i think) He shares this new home with 2 Discus that are as new has he is, They all seem to have settled in well and i plan to get a few more fish in the next few weeks. I’m totaly new to all this and was planning on putting about 15 fish in this tank but will lower it to round 10. Your site has great info about the care and welbeing of my new Betta, as i thought i would only feed him once every 2 or 3 days and with just a basic flake. I now know he needs a bit more care. My question is about the other types of fish i was going to have him flatting with i.e the discus, has they are bigger than him allready and fairly bright (silver, blue and black strips) would he be intimindated by them? I also plan a a few algie eaters to help lower cleaning, few clown fish and maybe 1 or 2 angle fish. Would this be to much company for him? my tank is a converted turtle tank that has the shelf (which he has claimed as his). I was also told that when i do clean the tank to only take about 20% of the water out to reduce the stress on my new found friends, with my algie eaters and filter i’m hoping to only have to clean once a month. Any feed back would help alot.

    1. Hi, your tank set up sounds good!

      I have heard stories of bettas and discus fish getting on fine, although it is something you should keep an eye on, their colors and shape can be a little intimidating.

      Angelfish are a bad idea, not only do their shape look like flowing fins to the betta, but the angelfish are aggressive too! You will find the angle fish picking on the betta and the betta fighting back, sometimes just nips which stress the fish but it could lead to a fight. Best to stay away from this combination.

  12. Well that is a small tank and carrying him around in it will stress him out. I strongly recommend a bigger tank.

    You will have to change his water very frequently in a tank that size so that he has conditions that will help him survive longer.

  13. i was just curious about how long they live,,,mine is about a yr old an hes still alive ,,i have 2 cats and my 1 yr old cat loves him,,he comes to he top of the tank an lets me pet it,its pretty cool..his name is catnip,,i hope he lives a long time….

    1. most will live 2-3 years in the right environment. But they can live longer! I have heard a few stories about betta fish that live to 6 years – 10 years is the record.

  14. Hi my betta fish spike is about 1+ year old water changes every week some times twice a a month but I also hav a hydro plant growing in the tank too he seems to like swimming between the roots etc… I was wondering what his lifespan will be the tank size is about 1.5 gallons thanks dudes much abliged

    1. Thanks for joining the conversation. As I mention the on average they will live 2-3 years. Your tank is a little small and if it doesnt have a filter it may not be as healthy as a betta fish in a big tank with a filter – although many people have mentioned that their betta fish has lived a long life in the conditions you describe. just remember keeping the water clean is very important! 🙂

  15. Hello I’m Angela and I have a question. Well in case of over feeding, do you have to wait a few days to let the betta get his stomach empty? Or do you keep giving the 2 pellets, which is now reduced?

    1. Hi Angela, yes if bloated from overfeeding it is best to give your betta fish a small fast of a day or two. Some betta fish owners actually miss a day out of feeding once a week / every 10 days at all times as it helps reduce the risk of constipation.

  16. Hello,
    So I’ve had bettas forever and I actually work in the pet care department at a pet store. I took a little guy home a few days ago and he’s nice and happy in a 5gal with a heater and filter. Lots of plants and a leaf hammock. His fins and body look fine, like no signs of ich or fin rot or anything. But he will not eat. At all. I’ve seen him eat one freeze dried bloodworm. ONCE. He doesn’t swim funny. And he’s actually blowing a bubble nest. So none of the other pet care associates (or myself) know what’s wrong. Any ideas?

  17. Hey, my betta just turned 3 years this August, and i think he’s dying, sleeps a lot, swims very hard and usually sided, and he hasn’t eaten for 2 days now, i don’t know what to do to make him more comfy, changed his water this morning (completely) thought he might feel better, but he didn’t react much, almost no stress sign showed 🙁
    if you know any way to make him feel better please tell me!

  18. ok i have 2 bettas and one is in a 1.3 gallon and the other is in a 2.5 gallon do i need to get a bigger one or are they ok you can go on instagram and look up my page @bettahelp11 one is a crowntail and the other halfmoon

    1. Hi Sophie, Betta fish can live in tanks that small but they thrive in 5 gallons! Happy and Healthy is what we want! 🙂

      Betta fish can get ill easier in smaller tanks so please remember to change the water frequently 🙂

  19. and my betta in a 1.3 gallon the crowntail is 4 years i just got my halfmoon two weeks ago and hes doing great one thing though i think he might have ick!!!!!:(

    1. Well, they dont need much to survive. However, is just surviving a good life??
      For a happy healthy long living betta fish, 5 gallons of personal water space is recommended! 🙂

  20. I just bought 2 betta fish and there are a few flakes of food left in their new tanks! I just put new water (room temperture with conditioner) in their bowls . But will they be alright if I wait to to clean the bowls in the morning (because of the coupke flakes of food) ? I want them HAPPY & healthy.! Please help!

    1. Yeah. But you should avoid leaving uneaten food in the tanks – this quickly dirties the water. Try feeding them less so less food is wasted. 🙂

  24. Nicole and Scalene

    Hi betta friends! I wanted to know if you have any advice on taking care of my new female betta, Scalene. She is in a one gallon tank just like my little sister’s male betta. She is not sick, but I just think a little advice might be helpful. Do you have any ways to keep her alive for a long time? Also, do female bettas get along with other girls? Girl bettas, not humans.

  25. Hey everybody! Just wondering what are the signs of a betta fish last remaining days? I’ve had my Byran for 3 1/2 years now, and he doesn’t seem the same like he used to be!

    1. Ford+Ice Flake family

      Kim I know from personal experience about what the final days look like. I’m only twelve years old and my 2 1/2 year old betta fish named Ford wasn’t stressed in his final days. He got a new 5-10 gallon tank. He used to be in a 1-3 gallon tank. He was a lot more happier in a bigger tank but it was his time. The last days are sad. First I saw he ate a lot less. Then he didn’t go for the food and ate off the bottom of the tank. Then he got pretty wide in a couple of days. I was scared and knew that was it. The next day he was not moving. Sitting at the bottom. We scooted his tank to see if he was alive but no he was gone. I love him. So I buried him today and got a new betta. A elephant ear male betta. He is small but he’s growing and happy. The pellets are too big for him so I feed him a really small amount of flakes because he is so small. Ford was old and grew purple and blue scales in his life time but started with some red. I miss him because he passed yesterday on Sunday January 3rd. I buried him on the 4th in 2016. The steps of death by old age scared me but now I know and u do to. Hope this helps good luck!!

  26. Hi I’m Frankie…I got my fish 3 days ago from a pet store. Before bringing home the fish was very active in the pet store. I have fish bowl. Now at home, the fish has become very lazy, always at the bottom of the bowl.Is this because of the weather? The weather is quite cold here. Please help me. I changed the water and that day the fish was happy. Now today its being lazy again. Please help me. I dont want it to die 🙁

    1. Hmm, you mention cold. Betta fish should be in water of 76-78 degreesF. Betta fish can get ill and act lethargic if not in the right conditions.

  27. Hi, I’ve had my betta for almost a year, and he is in about a 1 gallon tank. He has a castle that he loves to go in and a (fake) leaf hammock that he lays on. I have seen suggestions of putting plants in their tanks and was wondering if this meant fake plants or real plants? If it is real plants, what kind of plants can go in their tank? I am thinking of investing in a larger tank after reading your responses. Thanks.

  28. Hi,
    My fish Frank has been lately producing alot of bubbles in the fish bowl. What does that mean? Is it a safe sign?

  29. Hannah and Patriot

    My betta fish is just staying in one corner of his tank and not swimming at all. He also looked like he was going to fall but stayed up. Please tell us what could be wrong because I am very worried!!!!

    1. I have breed bettas for 15 years and have seen this condition go to your local pet store and ask for aquarium salt put a tea spoon in a cup and dissole it in aquaruim water then add it to your aquarium put the heat up to 30 degress wait a week and do a 1/4 water change drop the tempbackto 26degrees this should help

  30. Hi! I used to have a betta when I was ten, but it was a split (very small) tank with no filter. It died after about a year. 🙁
    I am getting a betta within the next month or two, and I want to be a much, much better owner!!! I was looking at the national geographic betta 2.5 gallon starter kit, and I’ll need a small heater, too.
    I don’t want to spend more than $20-$40, any reccomendations?

  31. Hi had a beta for 2.5 years he was good this morning and tonight I went to feed him and he’s dead at bottom of his vase. I have the big vase with plant on top. I just had hip surgery on Monday so I’ve been laying down and my friend came over and was cleaning kitchen where the fish was. Do you think the cleaning chemicals got in his water somehow and killed him? I’m sad. Thanks

  32. We just got our Betta a week ago, its in a little over 6 gallon tank and loves swimming around this helicopter we got for it. However we were curious as to how we could figure out the gender of the fish? Not entirely sure how we could do that.. Another question, we forgot to ask how old the fish was when we bought it at Wal-Mart-is there any way we would be able to tell how old it is?

  33. Hi our beta, Olaff, was doing fine and all of the sudden we noticed he was laying on his side at the top of the tank. He is still breathing and if you tap on the side of the tank (gently) he will move around but goes back on his side. He has a 3 gallon tank and we got him about 6 months ago. Any info would help as we love him and don’t want him to die. 🙁

    1. Hi, this sounds like your betta fish has had a problem with his swim bladder, not allowing him to float. This is not god as betta fish like to come to the surface of the water to breathe every now and again. Lower your water level so that it is easier for him to come to the top. Swim bladder disorders usually come from the betta fish being fed too much – they only have tiny stomachs and if these get bloated it effects the swim bladder. There is some great information here –

  34. My male beta keeps floating on his side. Hes also loosing color. I have him in a 1.5 gallon tank with a rock hide away. Fake plant and the bigger rock gems in the bottom. I can’t control the goop that keeps floating up top. I’ve had him a year.
    any ideas?. What am I doing wrong? Is he too old? Is he dying?
    Thank you.

  35. My sister wants a betta. I want 2 find facts 4 her but I’m not sure if we gonna get fishes (I want to name mine Macontash if a boy or if girl Apple #goldfishthough) Do U hav recomendations?

  36. Hi. Nice page. I have a Double Veil Tail and his name is Ormus. Named after the character in the 3rd act of Diablo 2 lol. Anyhow I just wanted to say that he is my first betta and they are great fish. I have him in a 20 gallon tall and I have it planted with about a dozen anubias nana and coffeefolia attached to nice drift wood. Bettas are such inquisitive fish. He swims and explores all day and I have him in with 9 dwarf zebra loaches which he sometimes chases from his favorite spots in the tank but they house well together. I can put bits of food on my finger tips and he eats from my hands. Anyhow, that is my fish story and I just wanted to say nice site.

  37. I have a fish named Twitch. He have a bowl with a heating light, but it is only 2 gallons, He seems to be happy, and I make sure that he gets everything he needs. Should I buy a bigger tank? What do you suggest. (my limit is $30)

  39. Angelia Holmes

    We have been taking care of our pet betta for over a year. His name is Pudro!! Is it safe to use bottled Nestle water for his tank or should we stick to tap water?? It seemd like the bottlef water doesnt get dirty as fast as tap.

  40. i just got a betta today i have a a 1 gallon tank for her i got a filer a plant, coditioner, flakes heat light and under tank heater is that enough for a month becuas im getting maybe a 10 gallon tank in 1 month

  41. Hi! I recently got a female “baby” betta from Petco, and she’s currently swimming in a 1-gallon tank with a fake log and 2 plants. I have a heater, filter, and water that is purified with these little dissolvable tablets. I plan to move her to a 29-gallon tank in about a week. But even with all of that, the water always seems a little cloudy and I sometimes find her resting on the gravel until she sees me. Is this normal? Replies appreciated 🙂

  42. I have a hard time believing that they need 5 gallon tank, filter, heater etc to live long and happy lives. My betta fish Blue is in a 1 gallon tank, no fliter and no heater. I clean his bowl about twice a month and he is over 5 years old.

  43. hello,
    I have 2 betta fish (female and a male.) The male is a bit older than the female. When I put the two fish together the male starts trying to eat the female. Any tips?

    1. Well it is – however it isnt recommended. Betta fish have a slime layer over their fins which protects them from bacteria and disease. Human contact can harm / remove this slime layer.

  44. Hello, I grew up with bettas i have had 5 of them in my life. My last one just passed away after 9 years a couple of months ago and my sister just got me a new one for my birthday. Do to living in a small space i habe kept all mine in a 1gl tank. For everyone that keeps theirs in a small tank my tip is on cold night i have a small desk lamp i leave on to fight off the chill. It has worked for me for years. I jave always feed mine one pelet in the morning and one around dinner time with sunday being a food free day. I always talk to mine where he sit on my desk. I find they are awesome little guys to have around i have even given one to my nephew who is 12 and has adhd we had clean tank day twice a month. I got him one because he use to come ovr an tell my fish how his day went. Point being is bettas are amazing to have kids love them as do is adults with love and care they can live long happy lives in big or small tanks.
