Lesion?

[alicia24]

Hi,
Sorry the picture/video quality is not great( they're in a bucket) I was transferring my fish from qt about to go into dt when I noticed my puffer has like a lesion near his tail. I'm assuming I nead to put all the fish back into qt? What else do I need to treat with? I already did copper, prazi, and kanaplex. Puffer seemed healthy other than swimming a little weird sometimes. Idk if this is a lesion from trauma from catching it.

This looks to be a physical injury and to prevent infection, I recommend immediate treatment using seachem Neoplex or kanaplex and assure it’s healing and not getting worse

Are you sure it didn’t have this lesion before you captured it to move it? It doesn’t look like a fresh injury to me, but maybe?

It looks like it might be infected. I’d move it back to the QT and dose with kanamycin again, especially if your previous kanamycin treatment wasn’t for the full six days. You could also try neomycin, but be sure your WT doesn’t have copper in it, because it can react with copper.
