very sick percula's

[jacksparrow7]

Aloha all, I really hope I can find a answer to this issue with the perculas here because I really like these little guys. I bought these fish at a LFS and quarantined them for about 6 wks and then put them into my MDT. I noticed after about 3 to 4wks later that one of the percula had what looked like scrapes on it side and the other one had some skin discoloration around it's gills. As you can see by the pics,it was no scrape and has progressed into something worse. I have moved the fish into a hospital tank and I am looking for a answer to what it is and what treatments are available if any. It probably is some kind of bacterial infection so I am looking into antibiotics. The tanks water parameters are great, nitrites/ates 0 (as far as a test kit goes) phos 0, ph 8.3, temp 79, mag 1500, cal 490. tank has been setup for 3 years and is a mix tank with sps and softies, tank matt's which show no symptoms are yellow tang, leopard wrasse, fathead anthias, potters angel, clam, fire and cleaner shrimp. All fish have never been aggressive to-wards each other and have been in the tank for several months or years. Mahalo for the help and any help is appreciated. Eric

Probably Aeromonas bacterial infection with a co-infection of the protozoan Uronema. Generally not treatable once it reaches this severity. If you want to try, isolate the fish (the Uronema is contaigous) and lower the specific gravity to around 1.020 to help with the osmotic imbalance in the fish. Don't go lower because Uronema thrives in brackish water. Then, dose a broad spectrum gram negative-acting antibiotic. Maracyn II is one type. Your dealer may suggest another - its all just a guess anyway. The problem is that this does nothing against the Uronema - and there is no way to treat that if the protozoan has dug down into the fish's muscle tissue....sorry.
