Microrasbora erythromicron or Danio erythromicron

A beautiful and very small fish that deserves its own tank. A 10 gallon tank will suffice for a group of 6-8, but the males' feistiness will be less damaging to each other in larger groups in more spacious tanks. The aquarium should have a dark substrate and be very heavily planted, and include floating plants. Pay attention to the specific water parameters or this fish will waste away. Regular water changes are also essential. The water in its habitat is very clean and crystal clear.
