That looks to me like a rhino pleco. If I see correctly it has 2 little protrusions by its eyes like horns. Kind of dark and lighter brown and a big sail looking fin? That would be a rhino pleco.
Yes, there are two fleshy looking things in front of the eyes. He changes his color... sometimes is dark brown all over, some times there are large patches of light brown.
