This ones tough. I want to say gibbi but the pattern on the belly is very different. I want to say l001 but the patern on the body is odd and belly is different.
What is the size of this fish and how long have you had it?
It could be one of the other Pterygoplichthys sp but that would be a long shot.
Wow, its got the best of both worlds. Id say flip a coin and enjoy your beautiful pleco. If my life depended on it is guess P. Joselimaianus based on the belly colors
