Hey guys, i have a problem. I introduced a marbled headstander into my 90 gallon tank about a week and a half ago. He is not eating blood worms, fish tablets or flakes. I keep my ph at 6.4 and do weekly 25% water changes. Im scared he is going to starve himself. Currently i have in my tank 2 large clown loach, 4 discus , a pleco and the headstander. Please help me.
