How to keep them

Keep more females than males so the males show off instead of chasing one fish. Plants bring out the best color.

Like every fish, they need a cycled tank, a heater set inside their range, and a weekly water change of about 25%. Test for ammonia, nitrite and nitrate before you add them. New to this? Start with how to cycle a fish tank.
