I have had this pleco for a LONG time and he is huge. He is 16 years old now and I noticed he has a raised brown spot on his side. I just notice recently and he is a common pleco so it definitely doesn't pair up with his coloration. Unfortunately I don't have a picture right now but I will try and get one soon. He has always been really crazy, by that meaning he sometimes freaks out and swims at the glass and one time he jumped out of the freaking tank. To be honest he looks healthy but I just don't want to overlook anything.
Any ideas?
