Appearance[change | edit source]

Males have a tendency to have longer caudual fins. They also "flare" their gill covers wider than females. They come in many colors.

The males will fight each other and can not be put together. They will also nip (bite) the fins of some fish. The females sometimes fight but can be kept in groups.
