How to keep them

Plan for 75 gallons or more and 5 or more loaches. They eat snails and shrimp.

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.
