Types of Betta Fish: Which Ones Are Best For Home Tanks?

Betta fish, also referred to as siamese fighting fish, have been a popular aquarium fish for many years around the world. But they are not just a domesticated fish. In fact, wild bettas can be found throughout Asia.

There are many different betta fish types, each varying in color, length, and tail type and shape. There are solid colored betta, striped betta, spotted betta, and even albino betta fish.

Choosing the right type of siamese fighting fish for your aquarium is important to ensure your betta fish lives a long and happy life.

Types of betta fish

There are many species of betta fish. Selective breeding has led to betta fish having more desirable traits that an aquarist may look for.

Betta fish in the wild also look different than those kept as pets. Domesticated bettas differ from wild bettas in many ways. Domesticated betta fish colors are usually brighter in comparison to wild betta. Wild bettas also usually have shorter dorsal fins, caudal fins, and anal fins than that of a domestic betta.

This article highlights the four types of bettas within the bubble nesting families: betta splendens, betta imbellis, and betta mahachaiensis, and betta macrostoma.

Betta Splendens

Most betta fish you would find in pet stores are Betta splendens, also known as siamese fighting fish. However, there are many species of betta that fall into the betta splendens family.

Halfmoon betta

Halfmoon bettas are one of the most attractive types of betta fish. They come in many different colors like copper, brown, teal, black, red, white, and green.

Their tail shape is what gives them their name. Their large tails, when spread, looks like the letter D, and looks like a half moon.

Most halfmoon betta fish have bodies that are two inches long and tails that add another three inches, making a total of five inches in length.

Halfmoon bettas can be aggressive towards other fish, and other types of betta fish, and will fight to the death if necessary. It’s important to keep male halfmoon betta fish separate from one another or else you risk dangerous fights between the two.

Plakat betta

Plakat betta fish are found most commonly living in marshes and puddles in Thailand, Vietnam, and Cambodia. These betta fish are known to jump. In the wild, they will jump from puddle to puddle to find mates and fighting partners.

Plakat betta fish grow to be just less than three inches in length, and can be vibrant in color, as seen commonly in domestic plakats, or more grayish-brown, more commonly seen in wild plakats. They have shorter tail fins and slightly shorter bodies than other betta fish, which make them more able to endure injuries from fighting. 

Because these fish are bred to fight, plakat bettas are more aggressive. Two males should not be kept together in the same tank. The tank should also be full of plants and other decorations to give the plakat a place to seek shelter as they would in the wild.

Stars and stripes betta

Crown tail bettas are native to Southeast Asia, located in Thailand especially. These fish usually have darker bodies with more colorful tails. They come in a wide range of colors. Their mouths are upturned and hinged.
