ah I think he means Columbian Shark Cats. They get big, you're looking at at LEAST a 100gal tank, preferrably bigger. These guys can get up to 1' and as most cats can be pretty active when they want to be. I may be mixed up here, but I THINK these guys may be one of the so called "tank busters". (known for smashing out aquarium glass with there hard heads)
