Betta
Betta is a genus of fish. Betta splendens is a common  species of this genus. Betta are very brightly coloured. They can be bought in a local pet store. Other species of betta are more rare. The males often show their aggression at other males as well as females by flaring at one another. Betta are surface breathers. They breathe air from the surface to make a bubble nest which attracts the female for mating. Betta fishes are found in small water bodies. These bodies of water are full of fallen leaf litter and peat that gives the Betta many places to hide.
