I came home today and saw Orchid's pale little body floating at the top, with his head lookinmg like it was just on the surface. His skin looks like it is peeling off, like shedding. and he is a lot paler than normal. He is hardly breathing, but every so often he flickers his fins. I panicked and did a quick water change, lowered the water level, and added melafix and some of the rid ich to the water, since it claims to cure other ailments. Oh god what could it be? He had no symptoms yesterday of anything! This is the fish that got me into fishkeeping! Oh, he just CAN'T die! What can I do? What IS it?
