These beautiful little rainbowfish are an great addition to a peaceful planted community aquarium. Ideally the aquarium should contain soft to medium water, vegetated and open areas and a fine and/or dark substrate. The fish are peaceful and males will actively display their colourful finnage both to attract females and as shows of strength to other males. Good general care and water conditions, as well as a correct diet will keep these fish in top condition.

Spawning occurs over vegetation | Natural Water Conditions pH 6-8, very soft to soft | Natural Habitat Streams & rivers | Sexing Males are more colourful with long trailing fins and will display readily.
