Bettas are some of the most beautiful fish species you can keep as a pet, and selective breeding practices have made it such that there are many interesting subspecies of Siamese fighting fish to choose from.

Today, you’ll get to know…

One type of Betta that stands out among other species is the Copper Betta fish, which is known for its bright colors and distinctively metallic-looking scales. This article reveals some things you should know about these types of Betta splendens and how to care for them.

Species Overview

Copper Plakat Betta fish belong to the Plakat variety of Betta. Like most Betta fish, Copper Bettas trace their origins to Thailand. However, you won’t find these fish out in the wild, as they’re bred in captivity, unlike wild Betta fish. These Betta fish are the result of breeding Half Moon Betta horns and Mahachainis or wild fighting fish.

Copper Bettas have beautiful coloration and shiny-looking metallic scales. They’re incredibly high-quality fish and have been selectively bred from other Bettas. Some of the most common colors of this Betta variation include metallic blue, turquoise, and steel blue. It’s worth mentioning that the Copper Betta fish resembles the Dragon Scale Betta.

They grow to be 3 inches long in adulthood, and their color isn’t set in stone during infancy. Therefore, if you buy the fish young, expect their final color to remain a mystery until they age fully.

Copper Betta fish aren’t too different from other Betta species in that they’re territorial and can be aggressive. Male Bettas may show aggression to other males, female Betta fish, and other aquarium fish species. The aggressive behavior may take the form of gill flaring, which can be stressful for these fish.

It’s a terrible idea to keep two males together, as they’ll frequently fight, sometimes to death. Meanwhile, the females don’t display as much aggression as the males, meaning you can keep two or more female Bettas together.

These fish are also highly intelligent, as is usually the case with Betta fish. Not only can they learn to recognize their owners, but they can also be taught tricks.

Like most Betta fish variations, Copper Bettas can live for four years with adequate care. While not the most long-lived fish species, their short lifespans make them great for pet owners who don’t want a high-maintenance fish (for example, goldfish).

Copper Bettas are susceptible to stress, which may leave them vulnerable to infections and parasitic fish diseases, which may prove fatal if left uncured.

Care Guide

To give your Copper Betta the best life possible, you’ll need to consider several factors during your fish-keeping activities. They include:

Tank Setup

Small tanks can be very confining for Copper Betta fish.Not to mention, the lack of hiding spaces will make them feel unsafe. Therefore, consider keeping these Bettas in a 5-10-gallon tank.

Moreover, Bettas are used to environments with lots of shade in the wild, and live plants provide them with cover. So, include some aquatic plants in the tank and keep the aquarium lights on a low setting. Copper Bettas don’t appreciate overly bright lights. Your Betta tank should also have a filter with a mild current for oxygenating the tank.

Like most Betta varieties, Copper Bettas aren’t highly active fish and so will retreat to a hiding spot when faced with a strong current.

Finally, your Copper Betta will tend to come up for air frequently. This behavior is due to its labyrinth organ, which allows it to breathe in atmospheric oxygen. Therefore, ensure there’s a lot of space at the top of the tank so that they can engage in their natural air-breathing behavior.

Water Parameters

Copper Bettas appreciate water temperatures between 75 and 80 degrees Fahrenheit. These temperatures are similar to what they’re used to in the wild, so you’ll want to mimic the above water parameters if you want your Betta to be happy.

These Bettas don’t do well in cold water and may not digest food well if the temperature in the tank drops below acceptable levels.

Therefore, a water heater and thermometer will come in handy when maintaining balance in the water.

Concerning water changes, you’ll have to tread a fine line. Do too many too frequently, and you risk stressing your Betta. But, on the other hand, don’t do enough, and the water quality may prove fatal to your fish. So, a good rule of thumb to follow is to keep the changes to once a week. Also, only change 25% of the water.

It’d be best to keep an eye on water hardness and pH levels. Copper Bettas will find it excruciating to live in water with a hardness exceeding 20 degrees of general hardness, so keep the amount lower. Meanwhile, your Betta will find water pH levels between 6 and 7 acceptable.

Nutrition Requirements

Copper Bettas are carnivores, so meat should be at the top of the menu. These fish will eat pellets, flakes, freeze-dried foods, frozen food, and live foods like smaller invertebrates and insects.

In the wild, Betta fish are known to eat mosquito larvae, small insects, and tiny invertebrates, so feeding them live foods is an excellent way to encourage them to exercise their hunting instinct. However, live foods are much harder to get and more expensive too.

Regardless of what you feed them, the critical thing to remember is that the food should float.

Food that sinks isn’t desirable as it’ll leave a mess at the bottom of the tank that can potentially ruin the water quality when broken down by nitrifying bacteria.

Tank Mates

Generally, Bettas are unfriendly to other fish due to their territorial nature. As a result, it can be a bit challenging to find tank mates they won’t attack or mistake for food. However, a few fish species and aquatic creatures can live in harmony with Copper Bettas.

For example, bottom-feeding fish species like Plecos tend to stay out of the way of Bettas. Also, algae eaters like Dwarf Crayfish know when to get out of harm’s way. However, remember that Bettas will eat any living thing they can fit in their mouths, so you might wake up to a missing tank mate or two.

Breeding Copper Betta Fish

Copper Bettas breed just like other Betta variations. You put a male and female in the same tank, and the breeding process will take course naturally.

It’s the male’s job to care for the fertilized eggs laid by the female.

You’ll know spawning has begun once you see a bubble nest on the water’s surface. Meanwhile, the eggs hatch within a couple of weeks, and the father takes care of the Betta fry until they gain the ability to swim.

After spawning has taken place, you’ll have to separate the male and female Betta, leaving the male with the eggs. The last thing you want is an injured female Betta due to aggression from the male.

Also, some Bettas are mouthbrooders, meaning they carry the eggs in their mouth until they hatch.Therefore, you won’t see a bubble nest during the spawning phase with these types of Betta fish.

The Makings of a Beautiful Betta Fish

Copper Bettas are handsome fish indeed. However, their beauty boils down to the variations in their scales, fins, patterns, and colors. So, let’s briefly explore some of these traits.

Tail Types

Bettas may be classified by their tail type into the following:

  • Crown Tail: Crown tail Bettas are so-called due to their spikey-looking tails that resemble crowns. Typically, the males are more brightly colored than the females.
  • Double Tail: Double tail Bettas have a pair of tails jutting out from their base and cleaved down the middle. These fish tend to have a shorter body and a lengthier dorsal fin.
  • Delta Tail: Delta Tail Bettas have tails shaped like the delta symbol (hence their name).
  • Round Tail: Bettas in the round tail variety share similarities with Delta tail Bettas. The difference is the edge of the tail of a typical Betta in this variety is fully round.
  • Spade Tail: Think of an ace of spades in a deck of playing cards; that’s the shape that Spade Bettas’ tails resemble the most.


Bettas bred in captivity come in various colors you might not see on their counterparts in the wild. A few of them include:

  • Mustard Gas: Mustard gas is one of the most typical colors on a Betta fish, and you’ll typically see it on a green fish with orange or yellowish fins.
  • Purple: Purple Bettas are legendary in the aquarium trade due to their rare color. You’ll be hard-pressed to find an actual purple Betta fish as the purple shading is usually tinged with lavender, red, or blue.
  • Black Orchid: Dark all over with some blue or purple highlighting peeking through, black orchid Bettas are split into three variations: Black Lace, Melano, and Metallic.
  • Rose Petal: Another ultra-rare variety, rose petal Bettas don’t neatly fit into a box. You may come across electric blue variations with a dark face and lighter body, among many other color variations.


The colors on a Betta’s body may be arranged into different patterns, giving them a distinctive look.

  • Butterfly Betta: Butterfly patterns usually end in a white or translucent tail. The bodies start with one color that ends abruptly toward the base, passing the baton to an iridescent color.
  • Marble Betta: You can identify marble Bettas by the distinctly blotchy color patterns all over their bodies. They usually have a pale solid color under the irregular pattern, while their fins may appear translucent.
  • Koi Betta: Koi Bettas are a selectively bred variation of Marble Betta, drawing inspiration from Japanese Koi fish. It isn’t easy to point to one primary base color since the patterns on these fish vary significantly.


Fish use their fins for swimming through water. They have several lone fins and some fins that come in pairs. Some Betta fish varieties stand out due to their fins, which may be wider or longer than the fins of other varieties, and have more interesting shapes.

For example, the caudal fin is usually the distinguishing feature of the rarest Bettas. Also, they may have a distinct anal fin, while the pectoral fins, ventral fins, and dorsal fins may jump out at you on other varieties.

Frequently Asked Questions

Are Copper Bettas rare?

Some variations of Copper Bettas, like the Rose Petal Bettas, are incredibly rare, so expect to spend a lot of dough if you’re lucky enough to lay eyes on one.

Can Copper Bettas live in a tank without a filter?

Yes, theoretically, they can. However, you’ll have to clean the tank every few days to ensure that the water parameters don’t change drastically.

Are Copper Bettas easy to care for?

Caring for Copper Bettas isn’t too challenging. They don’t require too much maintenance, most of the food they eat is readily available in pet stores, and they’re fine on their own.

Why don’t wild Bettas have fancy-looking fins?

You won’t find elaborate fin and tail types on Bettas in the wild because these features result from cross-breeding. It’s important to note that while these features are beautiful, they’d be impractical in a Betta’s natural habitat because they’d make it difficult to move through vegetation.


Copper Bettas are a gorgeous Betta fish variation that has shiny metallic scales. These fish result from years of cross-breeding, so you won’t find them in the wild.

Even though their appearance sets them apart from other Betta fish, Copper Bettas are still Bettas through and through, meaning they require the same considerations to make them happy. Some of these considerations include good water quality, adequate nutrition, peaceful tank mates, and a comfortable tank setup, to name a few.
