I think so just make sure its wider than it's mouth. Pacu's, Silver Dollars, and the like would be good tankmates as well as other wide-headed cats. Like Trachycorystes, Liosomadoras(Jaguar cats) and heavily armored cats like Megalodoras and O. Niger. Just leave no slender-bodied fish which can be folded in half ie Arowanas, Polpepterus, Pike cichlids and the like in with one as the cat will bend it in half to ingest it.
