One of my smaller blue chromis has suddenly what appears to be a blister completely covering one eye. He appeared healthy yesterday, and all other fish in the tank are healthy. Could this be an injury or an infection? I have not added any fish or corals or made any changes to the tank in months. Seems very out of the blue.
Apologies for the algae on the glass, hope the picture is clear enough?
