Hi everyone,
Hope you all are keeping safe. I have a large Maculiceps tang that I’ve had for quite a while. He is a great fish that is healthy weight and was very active. About a week ago, I noticed his entire lateral on one side of his body was inflamed and bulging out. I had never seen it before so I decided to change water and test parameters. All the parameters were fine. I haven’t made any new additions to the tank in over 6 months. The inflammation went away but yesterday and today I’ve noticed that one of his eyes is larger than the other, its definitely swollen. He is also hiding. Above his eye there also seems to be a small hole that is red. All my other fish are doing great. But the maculiceps is definitely unhappy, hiding on one side of the tank, and not actively going out for food. He is also breathing more rapidly than normal even though he is mostly swimming in one place.
I can’t get a great picture of him. But I’ve taken 2 which show the side where the eye is swollen. He also “hides” his other side/eye to the back wall but there is nothing wrong with his other side. Could it he trauma? Hole in the head or lateral line? Popeye?
I honestly don’t know what to do. I don’t want to unnecessarily stress him by trying a bunch of things, because that may exacerbate whatever problem he has.
Any help or thoughts would be really appreciated!!!
