I pickup five of these plecos the other day. A couple came out of hiding last night, so I took some pics. My best guess on species is Peckoltia sp. L134. They were unmarked, they didn't even know they had them, and they had no idea what they were. Does my guess look right? They are about 1.5" with yellow and black striping. Sorry about the poor quality pics, my cell can only zoom in so well.
