How to keep them

Keep the tank at 80 to 84°F, change water often, and add them only to a mature tank. Avoid shrimp you want to keep.

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.
