About
The Kamaka Rainbowfish (Melanotaenia kamaka) is a member of the rainbowfish family, a group well-known among freshwater keepers for their active swimming, schooling behavior, and the way males display to each other and to females. Like most melanotaeniids, this species shows its best colors when kept in a group, with males intensifying their hues as they jockey for the attention of females or spar with rivals. Rainbowfish in general are mid-water swimmers that appreciate a longer tank with some open space to move, though planted areas along the sides and back give them a sense of security and set off their colors nicely. The Kamaka Rainbowfish falls into the intermediate care category, so while it is not particularly fragile, it rewards keepers who pay attention to water quality and provide a varied diet. A school of six or more will show far more interesting behavior than a smaller group, and males in particular become noticeably more animated when they have companions to interact with. If you enjoy lively, social fish that reward observation, this rainbowfish is a solid choice for a well-maintained community setup.
