Natural habitat

Dwarf Rasboras are typically found in slow-moving streams and flooded areas with plenty of vegetation. The waters are slightly acidic to neutral, with soft to moderately hard water, providing the ideal conditions for these small fish to thrive.

Where they are found

This species is native to Thailand and Myanmar, where it inhabits still or slow-moving waters, usually found in dense vegetation.

Aquarium care

In the aquarium, Dwarf Rasboras thrive best in planted tanks with stable temperature and water conditions. They require a minimum tank size of 37.8541 liters (10 gallons), but larger tanks of 56.7816 to 75.7082 liters (15-20 gallons) are recommended to provide ample swimming space for schools of 8-10 or more. Regular water changes and proper filtration are essential to maintain their health.

Feeding

Dwarf Rasboras are omnivorous, thriving on a varied diet that includes high-quality flake foods, micro-pellets, and live or frozen foods such as daphnia and brine shrimp. They have a small mouth, so smaller food particles are best for them.

Compatibility

These fish are peaceful and should be kept with other small, gentle fish such as ember tetras, small Corydoras species, dwarf shrimp, and various small rainbowfish. Avoid housing them with larger fish that may see them as prey.

Breeding

Breeding these rasboras is relatively straightforward if conditions are suitable. Providing fine-leaved plants will help them lay their eggs, and soft, acidic water may promote spawning.
