Assorted Rainbowfish

Rainbowfish are arguably the fish that put Australia on the map, there are hundreds of species and even more regional variations. These fish bring vibrant colours and dynamic energy to any freshwater aquarium. Originating from various habitats across Australia, New Guinea, and surrounding islands, these fish are celebrated for their striking iridescence and diverse colour patterns. Because of how hard it can be to choose one species, this assorted rainbowfish option makes it like a surprise draw of different species.

Rainbowfish are an incredibly fun species as they are generally hardy and adaptable to a range of aquarium conditions. These active swimmers thrive in well-oxygenated water with plenty of space to roam, showcasing their splendid colours and peaceful nature. They are known for their schooling behaviour, making them an excellent choice for a community tank where their active and interactive nature can be fully appreciated. The appearance of rainbowfish can vary significantly from one species to another, featuring a kaleidoscope of colours including blues, reds, greens, and yellows. Their bodies are elongated with broad, laterally compressed flanks that catch and reflect light, creating a dazzling display. Males are typically more colourful and slightly larger than females.

Breeding Rainbowfish in captivity is a rewarding experience, with many species readily spawning in well-maintained aquariums. A typical breeding setup includes slightly softer and more acidic water conditions than their regular tank, with fine-leaved plants or spawning mops for the females to deposit their eggs. Post-spawning, parents may need to be removed to prevent egg predation, and the fry can be raised on a diet of infusoria or finely crushed flake food until they are large enough to accept larger fare.

Tank Recommendations for your Assorted Rainbowfish

A spacious aquarium is essential for keeping rainbowfish, with a recommended minimum size of 150 litres to accommodate a school and allow for their active swimming behaviour. The tank should mimic their natural habitat, featuring a combination of dense plant areas and open swimming spaces. The substrate can vary, but sandy or fine gravel substrates are preferable. Water conditions should be kept clean and stable, with a pH range of 6.0 to 7.5 and temperatures between 24-28°C.

Suitable Tank Buddies

Assorted Rainbowfish are peaceful and adaptable, making them well-suited to a community tank with other similarly sized and temperament species.

Usually Compatible

Small to medium-sized tetras, barbs, danios, and other rainbowfish species. Peaceful bottom dwellers like Corydoras and smaller plecostomus species also make good companions, as do dwarf cichlids and gouramis.

Sometimes Compatible

Convict cichlids, pearsi cichlids, and other peaceful or territorial species.

Rarely Compatible

Large, aggressive fish that might see rainbowfish as competitors or prey, such as larger cichlids, or species known for fin-nipping, could harass the rainbowfish.

Feeding your Assorted Rainbowfish

Melanotaenia species are omnivores that will love a varied, protein-rich diet. A combination of high-quality flake food, pellets designed for freshwater fish, and live or frozen foods such as brine shrimp, daphnia, and bloodworms will ensure your rainbowfish are receiving a balanced diet.
