He was raised as the only Cory for the first year and half of his life. They try to school with him but maybe it's because they are annoying kids. The one I thought was a female was panda and really the only one he showed interest in but I think because she was female(she didn't make it died shortly after I bought her poor breeder). But he never seemed interested in schooling with the others, I found out about them needing schools when I tried figuring out what was wrong with him. His eyes are still pink. When they turned they slowly got darker over a few days then stayed black for a couple weeks, during that time he acted depressed or something, not cleaning as usual. Thats when I tried buying him friends and stuff . Eventually he got better. But honestly he just seemed really blind during that time. Like he had to stay on the border of the glass because if he swam through the middle he would crash into something. He acts completely normal, like he did before the black eye plague. Just likes to be left alone
