Aquascape has them. But but finding one at a petstore around you might be more of a chalange. it sould be like 60-80$ extra to ship them but sometimes paying that much extra is better than driving long distence and paying for gas and toll roads.
I've been dying to get a hold of one of these, but the only place I can find them is on aquabid, and the price is a little high for me. $135 + shipping I believe. I've been staring at the same 2 auctions for months now. The fish started at 4", and I think they're up to 5-6 inches now.
