Neon Blue Gourami
Many gouramies have an elongated ray at the front of their pelvic fins. Many species show parental care: some are mouth brooders, and others, like the Siamese Fighting Fish (Betta splendens), build bubble nests. Currently, about 90 species are recognised, placed in 4 subfamilies and about 13 genera.
The name Polyacanthidae has also been used for this family. Some fish now classified as gouramies were previously placed in family Anabantidae. The subfamily Belontiinae was recently demoted from the family Belontiidae.
