My tank has turned for the worst in the past 24 Hrs my other half toped of my tank and all went to hell my salts sky rocketed my fish instantly started to die So as soon as I could I did a semi water change. Now all my levels are great and I am left with my clown and a chromy the pet store said with the water change my fish should be fine.But know my clown looks like he is loosing his color and has white spots covering his whole body and seems extremely ill (so sad) I want to help him he has been with us for a long time I can't stand to see him die. FYI: the other fish that is left is fine, prior to my catastrophe my clown was in great health IDK what could of happened besides the obvious water issue. If anyone has any suggestions please let me know! !!!!!!
