A basic guide to keeping Rainbowfish.
Papua New Guinea, Irian Jaya, Australia
Minimum aquarium size - a minimum of 90mm x 380mm x 300mm (36” x 15” x 12”) aquarium is necessary for Rainbowfish. If you are intending to keep a few species, a larger tank is necessary.
Temperature - fairly wide range in their requirements, from 18o/28oC (65oF/82oF).
Water parameters - Rainbowfish are very undemanding. Providing the water is clean and clear, they will accept hard and soft water. A water change of 25% each week is beneficial if not essential.
Habitat - Rainbowfish prefer a well planted tank, with some water movement created by an air-stone or filtration. Plants: all species of tropical plants are acceptable in the aquarium. These species do not eat plants.
Can be aggressive with smaller fishes. With similar sized fish, these constantly active fish are fine.
Omnivorous. All types of dried, frozen and live foods such as Daphnia and Tubifex worms. Vary their diet and do not overfeed.
Only select fish that are alert and swimming with fins erect. Inspect carefully for signs of disease. Reject lethargic, damaged or hollow bellied specimens. Rainbowfish are generally free of health problems, though may get a touch of mouth fungus if damaged in that area.
Habitat - freshwater tropical aquarium
Behaviour - fine with fish of same size or bigger
Care - easy
