Hello, folks. There seem to be quite a few knowledgeable people prowling the pleco board, so I figured I would see if you could help me figure out what this pleco might be. It was sold as a 136b snowball pleco, but someone on another board said that it is not but was not able to provide me with an ID. I've searched around a bit and have found nothing. So, here are some pictures. Thanks in advance for any help!
