I know a little about these cats they're on planetcatfish http://www.planetcatfish.com/scripts/clog_link.php?q=aguarunichthys+torosus. They max out at around 14 inches and from what I hear they're predatory, but peaceful. I've been tryin to get my hands on one NECichlids had some last month, but I just missed gettin one Nick was out quickly. If you're interested in buying one he's probably your best shot since I haven't seen them anywhere else.
