Galaxy Rasbora
One of the most striking nano fish in the hobby: a deep blue-green body scattered with pearl spots, and fins flushed with red. Small, peaceful and best kept in numbers where the males display to one another constantly.
Feeding
Very small foods only. Crushed micro-pellets, powdered flake, frozen cyclops and baby brine shrimp. The mouth is tiny, so anything larger simply gets ignored.
Compatibility
Peaceful but easily intimidated. Best in a species tank or with other nano fish. Keep in groups of eight or more, ideally with more females than males.
Behaviour and personality
Males colour up dramatically and spar harmlessly with one another in front of females. Shy in open tanks; confident and constantly visible in planted ones.

The Galaxy Rasbora are stunning with their vibrant blue-green bodies and red fins. I kept them in a 10-gallon tank with plenty of live plants and they’re very active. The males show off beautifully when there are females around. Feeding is easy with powdered flake and baby brine shrimp.

I bought a group of eight and they’ve been thriving. They’re peaceful and don’t bother other fish. The coloration is impressive, especially in the evening light. Just make sure the tank has plants to give them confidence.

Great addition to a nano fish community. They’re small but look amazing. I feed them daily with crushed micro-pellets and frozen cyclops. They stay calm and don’t chase or jump around like some other species.
