Look if your still not sure what it is then look it up. It is a very common pleco at least where I live it is. It is a gibbiceps I am 100% sure I have looked at so many gibbiceps pics it I the one pleco I could identify positively. It makes it hard to identify for some people for its colors are light from the stress while being in the bag. It is indeed a Gibbiceps yes its true its true.
