About Kali Tusa Rainbows

Kali Tusa Rainbows are a beautiful and relatively uncommon Australian rainbowfish prized for their shimmering colours and active schooling behaviour. Mature males can develop vibrant blue, green, yellow and reddish tones, particularly when displaying to females.

These peaceful fish are best kept in a group, where they feel secure and display their most natural behaviour. They are active swimmers and appreciate an aquarium with plenty of open swimming space alongside areas of dense planting.

Kali Tusa Rainbows are well suited to peaceful community aquariums and are an excellent choice for aquarists looking to keep something a little different from the more common rainbowfish varieties.

Common Mistakes

Keeping them in very small groups
Rainbowfish are social schooling fish and generally do much better when kept in groups.

Using an undersized aquarium
They are active swimmers and require adequate horizontal swimming space.

Overcrowding the aquarium
Allow sufficient open water for the group to move naturally.

Feeding only one type of food
A varied diet provides better overall nutrition and can support stronger colouration.

Keeping them with aggressive tank mates
Aggressive species can stress these otherwise peaceful rainbowfish.
