I recently "inherited" a pleco from a friend of mine. He is at least a year old, and is about 5 inches long and was living in a 10 gallon! The water was brown. Anyway I explained to my friend how big he will get, and she was shocked, since of course no one told her that when she bought him. So she gave him to me. I now have him in my 75 gallon (and he'll go to my 120 once we get it set up). My question is, how much do I feed him? I'm used to just feeding my fish what they'll eat in a couple minutes. I'm not sure how to judge how much he needs since I have yet to see him eat anything. Presumably he eats at night, b/c whatever I leave him, is gone the next morning. So far he's had wafers and zucchini. I'd appreciate any help you can give me! Also any food suggestions to help him grow would be appreciated. I'd love to see him grow big, though I'm not sure if he's stunted for life. Thanks!
