Not a great picture, I know. My starry blenny has been flashing, nipping at its own tail, and hiding for the past 2-3 weeks. He has been eating well still though. I know these are all telltale signs of ich or some other parasite/disease, but his coloration makes it very hard for me to tell. I also have 2 ocellaris clowns and a Firefish in the tank, and all of them look and act perfectly fine and healthy. All my fish were supposedly quarantined by my lfs, but now I’m kicking myself for not doing my own qt. Im hoping maybe someone could provide a little more input before I tear my tank apart trying to catch all my fish for qt.
For reference, I’ve had all the fish around 3 months with no previous issues or signs of disease or parasites. The tank is about 5 months old. Ammonia is 0, nitrite is 0, nitrate is 10, phosphate is 0.02.
