I got him about a year ago fo $40 and he was labeled as a tiger pleco but thats not very specific. Take a look
I know it's of the Hypancistrus genus ... but which one it's always ify for me never can really tell. Here is my personal guess, it's a variant of the zeb pleco from xingu. SO it could be an L174 or L399/L400 is my guess and not a tiger rather not a king tiger pleco. Sorry couldn't be of much help but I believe your pleco is one of those.
