well he looks like he is just playing with his food. he'll come up to the top when I take the lid off and act like he wants to eat then when I put food in his tank he will get it in his mouth, the let it go, chase it down and do it again. then he just goes back to the bottom of the tank.
and with his fins, he doesn't look discolored really, just paler. he's supposed to be a dark red fish, but he's becoming what appears to be more of a greyish red all over, not just his fins. His fins look shorter and much rougher around the edges, but not like they went through a paper shredder or anything like that.
thank you all so much for you're help though!!
