So I lost my onespot foxface over the weekend... Seemed fine as recently as thursday. Friday he seemed to be hanging out in the corner of the tank where he 'sleeps', but came around when I was near the tank and went after some pellets. Sat he started looking rough, not swimming, just parked under a rock. Never noticed anything on his body, eyes looked fine. Today he was just floating around, would swim a bit and I noticed his tail looked a little discolored and he had a spot on his torso that almost looked like a sting of some sort. A dot with some discoloration around it. I got him moved into my quarantine, but it was too late and he kicked the bucket this evening. I did get some pics and was hoping someone could id what the heck it was. After he died he discolored rapidly around his stomach area. Tank is a 120 and he was the largest fish. Only other inhabitants are a Kole tang, 2 clowns, 6 line and a cleaner shrimp. I've never seen the kole with his 'knives' out or anything aggresive at him. Everyone seemed good. I'm attemping to attach 3 pics. One in QT when I got him, one lying on the sand in the display where you can see the white dot low on his body and the 3rd is the autopsy photo where you can see his stomach changing colors... Everyone else in the tank seems fine, but i'm slightly concerned.
