Food and feeding
Not a fussy eater so use a small quality flake or granules for the staple diet but this must be supplemented with regular meals of live or frozen foods. As these are a small fish, offer them micro worms, grindal worms, daphnia or Cyclops.
Asia; Crossbanded dwarf rasbora is endemic to Lake Inle, Myanmar.
Females are slightly larger than the males with a stockier body shape.
Add some Java moss or spawning mops to the breeding tank and condition the parents on live or frozen foods for two weeks. When they are ready to spawn add them to the tank, spawning normally takes place at daybreak, the eggs will be deposited around the tank. Once spawning is complete, remove the parents and the fry should hatch out in 24-36 hours. A few days later the fry will be free swimming and can be fed on Infusoria.
The expected life span for Microrasbora erythromicron is 3-5 years.
A very peaceful fish, Microrasbora erythromicron prefer to be kept in small groups of at least 8 specimens. They will display their best colouration if the tank has subdued lighting and a dark substrate.
