Arapaimag has put it real well.
My original one is also from the same store - The Fish Place. They usually have one or two ~4"-ers for sale for about $35. Usually called cryptically "Amazon catfish".
Mine two have been growing at about half the rate of an average RTC. Not picky eaters as long as the foods are fleshy, not so much into pellets but will take them when starved.
For pics and aggression description, please take a look at my thread: http://www.planetcatfish.com/forum/viewtopic.php?f=7&t=34777&hilit=zungaro
They do grow bigger than RTC (not as striking in appearance though): look at the 4th picture down on this page http://httpwwwwasyphpb.easyphpbb.com/viewtopic.php?t=480
