If you are looking for a zebra pleco, they are still pretty expensive, but I hope in time the price drops as they are breedable in captivity. My daughter has an L-201 supposedly, but there are a lot of yellow spotted plecos too LOL. Join planetcatfish forum and post on the ID section. Those guys are great at IDing plecos. Make your title something like... ID needed, white spotted pleco. The more descriptive the title, the more likely the right people will look at the post. Get some good still photos of him, try to get mouth and head shots if possible as well as the full body shots.
