Costs of Keeping Bettas as Pet Fish

After discussing the different Betta fish prices of common varieties, it’s time to estimate how much keeping them will cost you.

Aquarium Costs

Here are the aquarium costs you should expect if you purchase Betta fish.

Fish Aquarium and Lights

Bettas love freedom while swimming with their large fins, so they need big tanks to live happily. If you plan on raising a pair of Bettas, you’ll need a 5-10 gallons tank. But if you want to keep more than that, you’ll need an even more giant aquarium.

Naturally, the larger your Betta tank is, the pricier it’ll be. The manufacturing materials also contribute to the price as some tanks have insulated glass. As a result, a high-quality tank might cost you anywhere from $50-100, and the lower-quality models can cost you $15-50.

Bettas can’t stay in the same light all day. Ideally, they should spend half of the day in the dark and the other half in the light. If you don’t have a space in your house where the aquarium can get natural light, you’ll need to purchase artificial lighting.

Some aquariums come with built-in lights, but you can purchase white LEDs if you don’t own one.

LEDs don’t increase the water temperature and will keep your Betta fish healthy. Purchasing tank lighting might cost you about $10 if you own a minimum tank size. But the bigger your tank is, the more you’ll pay for lighting.

Tank Decorations and Gravel

While not all Bettas are equally aggressive, they all like having hidden spots in the aquarium so that they can take a break from their swimming colleagues.

Accordingly, you’ll need to set up decorations like clay pots, live plants, fake plants, and glass marbles. You’ll most likely find them at your local pet store.

Live plants are better than fake ones because they resemble a fish’s natural habitat and pose fewer risks on Bettas’ flowing fins.

Luckily, not all decorations are expensive.

Some simple pieces might cost you as low as $5 each. However, larger pieces can cost you up to $50-100.

As for gravel, it’s an essential part of the aquarium because it holds plastic plants and completes the Bettas’ ecosystem.

You can buy sand, stones, glass marbles, or artificial gravel. These types all range from $10 to $50.

Aquarium Heater and Thermometer

Betta fish are tropical, and they love living in temperatures ranging from 78°F to 82°F. To get the optimal Betta fish temperature, you’ll need to purchase an aquarium heater. A thermometer will also come in handy to monitor the temperature closely.

An effective heater might cost you up to $40, but a lower-quality one can cost you around $10-20.

The price might vary according to the heater’s size. Luckily, thermometers come at reasonable prices ranging from $5-10.

Aquarium Filter

To keep your new Betta fish healthy, you’ll need to supply their tank with a filter. Bettas live in freshwater forest streams, and their natural habitats are often clean. Accordingly, they won’t like it if pollutants build up in their tank.

Like heaters and lighting, the price of the filter will depend mainly on the size of your Betta’s tank.

If you own a small tank, you might pay around $30. But if you own a large aquarium, you might spend up to $80 on a filter.

Filters have relatively high prices, but they’re essential for keeping your tank clean.

Care Costs

Although it’s somewhat low-maintenance, owning a Betta fish comes with a package of care costs. Here’s a brief roundup of the most important ones.


Bettas feed on tiny invertebrates in the wild, like brine shrimp, insects, insect larvae, and daphnia.

On the other hand, they feed on dried foods like pellets and flakes in aquariums. To maintain a healthy Betta fish diet, you’ll need to vary between frozen, live, and dried foods.

Lucky for you, Betta fish food doesn’t cost as much as the other aspects. You’ll only have to spend about $5 per week.

Water Conditioner

Fish simply need to live in water that resembles their natural habitat as close as possible, and tap water doesn’t offer this privilege.

If you plan on filling your Betta’s tank with tap water, you’ll need to condition it beforehand to remove harmful chemicals.

You can find tank conditioner bottles at any pet store near your place, and they won’t cost you more than $10 each. One bottle can last with you for more than a year.


While the difference might not be huge, owning a Betta fish can take your electricity bill up a notch. This is because of the aquarium light, filter, and heater.

As a result, you should keep this slight increase in your calculations to make sure you set aside a suitable budget.

Fun Fact: Another important factor to consider in buying an aquarium tank is the size of the fish you are going to take care of. Bettas are quite popular with beginners! We strongly suggest you read our article, How Big Do Betta Fish Get (When They Grow To Full Size) to learn more.
