Food and feeding
Cherry spot rasboras are not fussy eaters so offer a quality flake for the staple diet but this must be varied with regular meals of live or frozen foods. Daphnia, blood worms, micro worms and brine shrimp are ideal.
Origin
Asia; Cherry spot rasboras are mostly found in Northern Thailand.
Sexing
Males are slimmer and slightly smaller than the females. They will also display a brighter colouration especially at spawning time.
Breeding
Add java moss or spawning mops to the breeding tank and subdue the lighting. Spawning will normally occur at day break and the eggs will be scattered around the tank. Once spawning is complete, remove the parents and the eggs will hatch in 24-36 hours. A few days later the fry will be free swimming, at this stage they can be fed on Infusoria.
Lifespan
The expected life span for Rasbora rubrodorsalis is 3-5 years.
Short description
Rasbora rubrodorsalis are a really peaceful species of Rasboras that needs to be kept in small groups of at least 10 specimens. They make a great addition to planted set ups and using a dark substrate should bring out the best colouration in the fish.
