I don't specifically feed my pleco because i have tried for 6 months and h hasn't even made an attempt for the food. But what he does do is sneak a little of my polys food like bloodworms beefheart brineshrimp. All those times he has sat there and even sat on top of the algae wafer while eating the polys' meal. He steals those meals and the cleans of all my decor (which seems to constantly have algae even with him cleaning) But i just want to get s new algae eater that won't hurt my polys. I have decided some bristlenoses and corys. Thanks for all the input guys. Everything helped.
