Need ID for tiny pleco

[andre]

Hi, I got a little algae eater at petmart on friday afternoon, it was in one of those individual bags that they float in the main tank. However, I do not know its id, its a little spotted and patchy, its really tiny and dont look like it can get big, its at 1 inch currently, tried planetcatfish also already. Was selling for $10. if any of the experts can help would be great![:] PS its not an oto, tho i did pick up the zebra oto as well
