Skin Problem- Need Help

[Arthur12]

My Green Sunfish is in trouble. He was doing great in another tank, so well that I had to move him because he grew so fast. 2 Days into his new tank and he's got something that looks like is eating his slime coat. About a month ago I put in two fish that got the skin eating away, I thought maybe it was something they had in the wild but now I know for sure the problem is with my aquarium. I put in Prazipro yesterday and that seemed to make things worse. Also, two of my other fish have something abnormal on their dorsals, some missing skin and a white tuft.. What do they have and what medication will treat this? Fungus Cure from API? I need some help. Thanks in advance.

Please post ur water parameters. Could be fungus. API fungal cure should do it if it's fungus.

As Wailua Boy mentioned prior a MB dip would help this too. Especially on top of the API fungus cure.

Not exactly sure what it is..probably fungal as a previous post suggested. I have seen this in my tanks, in fact I am dealing with it right now. I do know it spreads to other fish quickly IME, and the treatments I have used were ineffective (prazipro, melafix, pimafix). The only successful "treatment" for me has been euthanasia to prevent the spread to other fish.

Update- The Green Sunfish died. I treated the tank with API EM Erythromycin. The two fish with something on their dorsal fin has gone away, but they were different symptoms than the Green. None of my other fish showed any signs that they were sick, nothing visual on skin or acting weird. That seems strange since the Green Sunfish was affected so quickly and aggressively . I still would like to know what happened, but really happy things didn't get worse.

Just to test the aquarium, I moved a Longear into the tank and it is doing great, no signs of any problems.

With my experience with fungus increase the flow as high as you can without it being un comfortable and do 50% water changes once to twice a day and increase the temperature try to find an anti fungal that he has never been exposed to like methleyn blue or something different as well as putting him in a hospital tank if you have not already done that.
Hope this will help
