In their natural habitat, Betta fish are typically found in small, shallow streams and rice paddies in Thailand. These are usually vast, and with the tropical climate, the waters are generally quite warm.
Betta fish will generally grow to around 2.5 – 3 inches (not including the tail). The size of the tail will vary with different species of betta but generally speaking, healthier fish tend to have bigger tails.
Plakat Bettas are a lesser-known version of the famed Betta Fish (Betta splendens). These fish are much closer in appearance to their wild counterparts, sporting a less dramatic tail and more robust build. Because Plakat Bettas were originally bred for competitive fighting they tend to be more aggressive than their long tailed cousins.
Bettas are labyrinth fish, meaning they have the ability to breathe oxygen from the surface of the water. Because of this, you should aim to leave some space at the top of the tank for your Betta fish to breathe.
