I use to have a wild caught albino oscar. I actually caught him in Florida, and what made him rare was his size. He was actually almost 9 inches long and for a fish to reach that size in the wild would be amazing given the disadvantage he would have colorwise. My guess is that he was dumped not too long before i caught him. Cool fish, had pictures when i caught him and eventually sold him to the LFS. Mean as hell that fish was and always made for a good story.
