hey guys, I recently got a free catfish from someone I bought a tank from. It would just swim around on the ground at first but when I added some plants, he will NOT stop sucking on the leaves. Is he or she cleaning? I doubt it is because he is hungry because I threw in a piece of shrimp which he could not finish. I saw him tear it up for about 1 hour and now hes back to the leaves. Is he or she going to kill my plants? if he is, I am afraid it might have to go. Help before it goes bye bye?
