I think I have an Adonis pleco. I don't know much aside from "there supposed to loose there spots when they mature"??? The specimen that i posses has no such dissapearing spots. All of the photos that look close to mine are not close at all. They have colored patches of skin. My fish has white spikes raised up off it's skin that appear to be permanent. If the info I was given was wrong or the sharp teeth things I see are just an illusion then what the hell do I have? I attached the best photo I could get. It is very illusive. I'm hoping it's clear enough I can get a positive ID. And then with the ID maybe even get some useful info on it. I have a 125 I want to put it in but I need to know if it will get big enough to compete for food or not.
