Hi there, I don't know if this is normal but my pleco always seems to be stuck on a plant leaf, usually the same plant, there are now numerous holes in the leaves which is fine by me but he doesn't seem to be doing much else. He did come out for a nibble on some cucumber last night but because all the other fish like it he was tending to dart back to safety. I do put an algae wafer in every night when the lights go out and its always gone in the morning. Then again I have two 4.5 inch clown loach who also like the wafers too. Do they prefer the dark ? Don't see him going around the glass but it is clean. Also he does seem quite plump, in a wide way if that makes sense and his scales are quite dominant, been trying to look at some pics of other plecos to compare. I asked the lfs if its possible it could be suffering with dropsy and he said he'd never known of a pleco have dropsy and couldn't imagine it would be. Because he doesn't come out much I can't determine whats normal and absormal really, getting a picture to post would be impossible I think. If it was dropsy or leading that way is there anything I can do to treat it. thanks fo any help !
