Hey I was just going to let everyone know that my Iridescent Shark has gone to fishy heaven.

I came home and found him at the bottom of the tank. He was starting to lose the spots but i noticed today that he was swimming at the top all day so I wondered if his time was about up. but I just thought i would let you know even after all your help which i very much appreciated. Im just thinking what I could have done, I feel really bad. I turned the heat up i changed the water and used salt which i should have been doing in the first place, and i was using meds. I think a little of it has to do with I still am working on getting that 55gl.
But all the other fish are doing well so that is a plus.
