Rainbowfish are native to Australia, Papua New Guinea and parts of Indonesia, found in streams, rivers, lakes and swamps. These locations are filled with overhanging vegetation, which should be replicated in any home aquarium. Aquatic plants are a vital part of the Rainbowfish setup. Additionally, an aquarium with plenty of space to swim will allow the Blue Rainbowfish to beautifully dart around in their group, providing a beautiful display of colour and activity.

Despite their size, Rainbowfish have small mouths, meaning any smaller fish, such as neon tetras, are safe. The diet of the Blue Rainbowfish consists of almost anything it can find. They are not fussy. Offering a balanced diet of protein, krill, algae dry foods, and some live or frozen foods such as daphnia, or brine shrimp will promote natural colour development and keep your fish as healthy as possible. 

Breeding Blue Rainbowfish is no different to other Rainbowfish. They tend to spawn early in the morning, and their eggs will attach to aquatic plants such as Java moss. It is a good idea to use a dedicated aquarium for breeding and prepare to remove the eggs once they are fertilised. Spawning mops are handy for this purpose. 

All our fish are quarantined on arrival for two weeks. During this time, we treat any health issues that may occur during transport and ensure each fish is eating well and looking healthy. In addition, all fish are treated with Flubendazole before finally going on sale.
