spotty? black over the eyes? black striped?
	
	how long were the bristles? And was there and kind of pattern to the black and white stripes? The 2 obvious answers to me are Striped Dora cat or talking catfish, or Red Tailed Catfish..
/www.bostonaquariumsociety.org/image...zebra_pleco.jpgthe answers on the back of your linkZebra Pleco. Are you positive it was one of these? they are relatively rare, and generally fetch a rather impressive price tag.
Just done a quick google, and found L260 Queen arabesque, and the Candy striped pleco, and a royal pleco
I've seen Royals in quite a few shops, then can reach 13" (according to planet cat), and are 'relatively' reasonable on price, so that seems likely, as it 2.5" already.
The candy striped i've never heard of, the queen i've heard but never seen, but both of these can reach up to 3" or thereabouts, making the one in your shop nearly full grown if it is one of these 2, plus the queen, and probably the candy will carry higher price tags that a lot of fish (not as high as a zebra tho)![]()
