They should not be kept with large, aggressive fish, but would enjoy the company of other small, peaceful fish as well as fellow gouramis. Loud noises often scare them, so the tank should be in a quiet area.
Traditionally silvery blue in color, their colors can change significantly with their moods, as well as during spawning, when they obtain a much deeper blue hue.
Because the male can be rather aggressive during spawning, the aquarium habitat should provide ample places for the female to take refuge. Failure to do so can result in injury to the female.
Compatibility: Livebearers, Tetras, Danios, Rasboras, Rainbowfish, Barbs, Loaches, Plecos, and scavenger Catfish.
