If they are underfed, Mie is right. Your coral banded will kill and eat your cleaner. If you have a tank of at least 40 gallons and a ton of rock to hide within, they will probably get along ok. I’ve had two of them together for about half a year and they don’t even get closed to each other. But I feed my tanks every single day, and sometimes twice in a day. Do everyone is happy.
Good luck man.
