Hey Sassy, and everyone who's been active in this thread. I came home and checked on my guy. He was on the bottom of the tank but swam around a little bit and then returned to the bottom again.
I got a kritter keeper and a plastic 1 gallon bowl from petco for easier dose mixing and whatnot. He's currently fluttering in the kritter keeper which is floating in the original 3 gallon tank he was in when I got home. I decided to do it that way to maintain the KK temp to match the 80° water in the big tank. Since I got home, I've noticed that his breathing is less labored but the labyrinth organ on his left side seems a little larger than on the right when he's breathing. I took pictures and I'll try to attach the best ones.
I don't know if that counts as "inflamed gills" as stated on the illness sticky but I'm treating him with a bit of aquarium salt and fresh water treated with Stress Coat and tapwater conditioner. I've slowly been replacing his KK water with today's fresh treated water. Once I think I can, I'll dump as much of the mixed KK water out and give him a full KK of the aq salt water.
I'm happier that he's not looking beached at the bottom of the KK and is actually swimming around some. His coloring on one of his pectoral fins is almost gone and the other has no color. I'm trying not to get my hopes up yet but I am glad he's off the bottom and fluttering around a little. He definitely had no "flutter" to speak of this morning. Not sure if I want to feed him yet.
Should I do 100% water change everyday with the aq salt water?
Thank you for all your help. ;o)
