Help ID my royal pleco?

[KnightDoughboy]

HI guys, I'm new to the forums and was just wondering what type of royal pleco do I have? I know there are a few out there, so I just wanted to make sure. Also, if you can tell the sex of it by this picture that would also be nice!
Sorry if the picture isn't clear, it was taken from my phone. Thanks in advance!
