How to keep them

Keep one male with a female or two, leave a gap above the water and add floating plants.

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.
