size:	Up to 3" (8cm)
position:	All
pH:	6.5 to 7.5
temperature:	73ºF to 86ºF

Community fish: Yes

Diet: Will eat almost all live foods and many prepared foods. But, it prefers flake food, freeze-dried bloodworms, tubifex worms, and brine shrimp.

Temperament: The males are highly aggressive toward their own kind (and toward similar-looking fish). They will sometimes attack fancy guppies (anything with big, colourful fins). Males should be kept alone or with a group of females. If kept with one female, the male will constantly pick on her.

Comments: An excellent beginner fish that can withstand very poor water conditions, small containers, and stressors well, due to its labyrinth organ (a kind of primitive lung that enables it to breathe from the surface). Although it can survive in these conditions, high water quality is important for them to thrive.
