I have no idea what this is. My brother just brought him over when he was watching my tank while I was out of town and left him. It may be a common but I have never seen a common with the type of eyes he has. They are like cuddle fish eyes. The pattern of his body goes all the way through his eyes. He also is constantly changing color. Like big change. If you look at him close to the glass he will change color in front of your eyes in a matter of seconds. This may be normal but I do not pay much attention to plecos. Thanks for any help!
