One of the more recent arrivals in the hobby, Parkinson's Rainbow Fish is a gorgeous fish, with bright orange and black highlights across their fins and body. Like most rainbow fish, these fish will not begin to show their adult colouration until they are at least 6-12 months old, and may look drab and silvery until they do.
An active, schooling fish, Parkinson's 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.
