I knew I shouldn't have gone into Petco. :( This guy looks pretty awful. His fins are a wreck; it looks like fin rot on his caudal, and his dorsal is shredded.
There are also a bunch of black spots on his dorsal fin. I know the pictures are terrible, but do they look like fin rot, his normal color, fungus, or something else?
He's also got some black spots on his body. Are these lesions/scars, or could they be fungus?
I was planning on putting him in an 82* 1 gallon hospital tank with no substrate, just a silk plant, and an aquarium salt treatment (1 tsp, daily water changes for 7-10 days) to treat his wounded fins and kill any potential parasites, but if he has a fungus I don't really know what to do, so any help would be greatly appreciated.
I don't know if I'm imagining it or not, but it seems like his breathing is labored, so I'm afraid he might not last long. But if he doesn't make it, at least he will have gotten to leave that nasty little cup for a while. If anyone has a diagnosis, and/or advice for treatment I'd love the help. Thanks.
