Keeping Emerald Dwarf Rasbora in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: peaceful
  • Diet: omnivore
  • Minimum tank size: 10 gallons (38 liters)
  • Compatibility: Excellent for community tanks with other small, peaceful fish such as other dwarf rasboras, microdevario species, small tetras, corydoras, and peaceful shrimp. Avoid housing with larger or aggressive fish that may prey on them or outcompete them for food.
  • Special requirements: Requires a well-planted aquarium with plenty of hiding spots and open swimming areas. A dark substrate can enhance their coloration. They are sensitive to poor water quality, so stable parameters and regular water changes are crucial. Best kept in groups of 8 or more to encourage natural schooling behavior and reduce shyness.
