My friend has had his turtle for several years now and I think he knows as well as I do that his turtle's care isn't quite purfect. He has been fed on comercial feed only since he was caught in the wild, and the filter has been too small, and his tank was small as well. The turtle also has some pyramiding (this isn't reversible, is it?). But my friend just upgraded the tank and the filter, and the water quality has gone up a ton to where it is crystal clear when it used to turn brown and murky within a week. But now, whenever we lift the turtle out of the water, we can hear his breathing, raspy and loud. Does anyone know what could have caused this, or what "this" exactly is? What could be done to help? My friend and his turtle, Irvine, will appreciate any helpfull advice.
