Most of them live in shallow water areas such as mountain ponds, rice fields and springs, and eat invertebrates. During the breeding period, males spit foam as nests and gather their eggs in the nest. Males have the habit of protecting nests. The individual is small, because of its bright body color, and the male fish is a good cow, which is a famous ornamental fish.
