Scientific Name is Cephalosilurus apurensis
I had to give that fish away unfortunately, but while I had him he had an interesting personality. Most of the time he would hide under a log, doing battle with my 15" common pleco over hiding spots. He would also hide standing on end behind one of the standpipes. When feeding time approached he would float vertically so his mouth was only an inch or so from where I normally dropped the food in. It was always entertaining to watch him move my driftwood around and route the pleco from his hiding spot. Never seen a pleco look so pissed off!
