I lost several fish over the winter and a few recently. I now have 1 that remains that has a serious SAP infection.
The one with the serious SAP issue has been in a quarantine tank for just over 2 weeks. The first weekend I treated with three doses of proform C, with the first dose the tank had all new/clean water. I did a 25% water change before the next two doses. The following weekend I did it again, I had lost one of the fish so I was down to 2. Before dosing I used a brush with salt to remove as much of the SAP as I could. I then put peroxide on the affected areas and denture powder. Did 25% water changes prior to each dose and did that 3 times. I lost one more. The ,last one grew a bunch of the SAP back, I used a brush and salt, on the back half of the fish a bunch of the skin started coming off. I treated with iodine then denture powder, did a 50% water change and not sure what to do with him next. I need ideas. I don't feel like the proform C is doing anything.
I the pond, the remaining fish were looking good. Very active and eating (it's finally warmed up here!) Yesterday I noticed a couple of fish with brown fluffy spots. I netted this morning, looks like SAP. I treated with salt ad a brush, I put iodine and neosporin on the infected areas after getting the SAP off. I covered with denture powder and released back into the pond. I'll keep a eye on them but I (probably foolishly) feel like they may be okay.
I also have some really nice fish in my other quarantine tank, I was going to put them into the pond today (been four weeks) but I'm afraid to.
1. What can I do for the poor fish (family favorite BTW) with the skin that's falling off?
2. Anything I should have done differently or should do/watch for, for the two in the pond?
3. Do I just keep the nice fish in quarantine until some time in the future and if so when can I release them?
