Melanotaenia australis
Parker's Rainbowfish, Northern Rainbowfish
Melanotaenia australis are highly social creatures, best kept in schools of six or more to ensure a vibrant and active tank dynamic. This species is noted for its adaptability to various water conditions, making it a good choice for both novice and experienced aquarists. They exhibit peaceful behavior but should not be housed with significantly smaller fish, as they may outcompete them for food. Additionally, a well-planted tank with ample swimming space replicates their natural habitat and encourages natural behaviors.
