We have a Common Pleco, about 5 month old, and has been doing great up until now. He has been spending alot of time hiding and not out and sucking around like her normally did. When I lifted up his hiding spot today (to make sure he was still alive) he was alive but had alot of pale spots on him. will try to get a picture if he comes out. We thought it might be because our rosie barbs are going to be breeding soon, would that be a possible reason. We are afraid he is going to starve since he doesnt come out to eat. Any thoughts?
