No offense, but it doesn't really look like anything that special to me. Maybe a cool coloration, but it is likely a common or sailfin. The link I posted in the first response will give you an idea. There are literally 100s and probably closer to 1000s of pleco species and variations with the majority of them not yet properly described. To properly ID them requires multiple specific trait analysis and a ton more experience than just about anyone here has. Again, no offense is intended. Toddnbecka would be about the only "expert" that comes to mind on this board. Speculation and guesses will likely only leave you with false hope and misconceptions of the fish's needs. And worse yet, may lead someone else who finds this thread in months or years to make the same mistake. JMO
