sores on blue gourami
To start, my tank is 55 gallon with 2 silver dollars, 3 clown loaches, and a pleco. The water parameters are within normal limits. I have many fake plants and several large "rock" forms, so there are many places for the fish to hide. About 2 months ago my Blue Gourami (Trichogaster trichopterus) started to develop sores on it's body. I first put in one of those all inclusive formulas. I don't remember what it was off hand. That did nothing. Then I started to use Tetracycline( 3 days), because at the time, the store was out of Maracyn-II, but that created such high foam(3-4 inches), the fish were unsuccessfully trying to jump up over it to get to the surface. I got some Maracyn-II and started using it. Unfortunately, then we went away and the "sitter" continued to use the meds as instructed. And did one course of treatment. Then another 10 days passed until we got home. The sores were still there and there were more of them. I then treated with both gram negative and gram positive, Maracyn and Maracyn-II for 2 courses of treatment, because it was working so well; and the sores were healing up and no others were appearing. After the treatment, I did water changes and returned the filters, as instructed. 5-6 days later the sores started to reappear. Now I've been treating for another 2 courses, but still getting new sores. Other than these sores, the fish is behaving normally and eating fine. The sores are very raw looking, various tones of light pink to dark pink. Then look translucent. I'm at a loss as to what to do that could stop this. Would also like to know you're best guess as to what it is.
I have included some photos. This is the first time doing this with photos for me. I hope it works.DSC05074.jpg DSC05079.jpg DSC05085.jpg DSC05091.jpg DSC05109.jpg DSC05110.jpg
