One of my White Skirt Tetras has a strange white growth on its eye. It is in a 30 gallon tank with 5 white skirts, two freshwater angelfish, two blue ram cichlids, and a chocolate zebra pleco. It was one of the first fish in the tank and has had this weird growth for as long as I can remember. It hasn't gotten worse and the fish seems happy and healthy otherwise but it still raises some concern. I'll provide a picture of its healthy eye and abnormal eye with this post. It would be great if someone could identify what this is as I am concerned it could put my other fish at risk.
