Care Requirements
Tank Size:
A minimum tank size of 60 litres is recommended, though larger aquariums are preferred for groups. These fish are very active swimmers and benefit from horizontal swimming space.
Water Parameters:
Dwarf Rainbowfish are hardy and adaptable but thrive best in stable conditions:
Temperature: 23–27°C
pH: 6.5–7.5
Hardness: soft to moderately hard
Clean, well-oxygenated water is essential, as they are sensitive to poor water quality.
Filtration & Flow:
Moderate filtration with gentle to moderate flow is ideal. They enjoy some current but should still have calmer areas to rest.
Aquascape & Environment:
A planted aquarium with open swimming areas works best. Use fine-leaved plants, driftwood, and darker substrates to enhance their colour. Floating plants can help diffuse lighting and make them feel more secure.
Diet
Omnivorous and easy to feed. Offer a varied diet of:
High-quality flakes or micro pellets
Frozen or live foods such as daphnia, brine shrimp, and bloodworms
A varied diet helps maintain strong colour and overall health.
Social Behaviour:
Best kept in groups of 6 or more, with larger groups producing more confident behaviour and brighter colours. Males display their best coloration when competing gently for female attention.
Tank Mates:
Peaceful and suitable for community tanks. Compatible with small, non-aggressive species such as rasboras, tetras, Corydoras, and peaceful dwarf cichlids. Avoid slow-moving or long-finned fish that may be stressed by their constant activity.
