...hoping someone can help or point me in the right direction. My 1 year old Angel fish has not eaten in a couple of days and seems to have clear poop coming out. He is also swimming fine but stays at either the top or bottom of the tank in the corner. No other visible signs of illness are present on the fish. He is usually swimming around like crazy and eats a ton. He also seems to be breathing a little heavy. The only thing I can think of is some sort of a parasite but don't really know how to diagnose or treat that. Any ideas of what this could be?? ALL other fish in tank are fine and nothing has changed or been added to tank for quite some time....except for water change today.
