The Turquoise Rainbowfish displays an unusual dark green colouration, which is often evident even in smaller, juvenile fishes (though smaller individuals, like all rainbowfish, are generally plain, silvery fishes). This dark, turquoise colouration makes these fish stand out in most aquariums, and a shoal of these medium sized rainbowfish is a sight to see! The Turquoise tends to be fairly hardy, but should not be kept in soft, acidic water.
An active, schooling fish, Turquoise Rainbow Fish should be kept in large groups, with a minimum of six fishes. They are unaggressive, and can be mixed with virtually any other community type fishes. They should not be mixed with large cichlids, or othe fish which may eat them. They make excellent dither or target fish for smaller, moderately aggressive cichlids, such as Pelvicachromis. Their bright colouration can also make them a focal point in a planted aquarium.
Care should be taken when mixing similar species of Melanotaenia, as they may hybridise in the aquarium.
