Betta fish can communicate through colors and body language. A betta fish can use fins to show it is ready to breed, and can change its skin to have black or dark vertical bars to show it is ready to breed. A male can communicate to other males to stay away by flaring it's fins and fanning it's gills at it's intruder.
