i dont think my pleco has been eating lately. his stomach is slightly concave. i feed him algae wafers and he usually gets sinking carnavore pellets i feed my catfish, and koi pellets but i haven't seen him do that lately. i also got some lettuce rubber banded to a rock, i just put that in, idk if he touched it yet. i think the koi are eating his wafers before he can get to them. i drop them in after the light has been off, but they still get them. anyone got any suggestions on how to keep the other fish from eating his wafers? and, any other suggestions on what else to try? this pleco has really grown on me and i would hate to lose him.
