I bought 3 spotted corys a few days ago and they look great except the largest one's eyes are completely black. He/She is missing the gold iris type ring. They may be protruding a little or it may just appear that way, not sure. He looks happy and healthy. His dorsal fin might be a little damaged as well. some of the webbing may be missing at the ends. I'm more concerned about the funky eyes. Thoughts?
