Scientific Name Pangasius sanitwongsei
Common Name(s) Chao Phraya Giant Catfish, Paroon Shark, Pla Tepa
I think I recall vaguely someone calling Paroons a High-Fin Shark, Emperor Shark, etc. So, the answer is no, IMO. Yet, I'd not be surprised that different local names exist for various Pangasiids (there are at least 12 recognized species and I'm sure more is coming) and show up in the hobby and, hence, there easily can be confusion. Emperor is an easy name to use for any majestic, big fish. For example, consider hybrid synos: any striped fish can be called a zebra or a tiger syno and any spotted fish ca be called a jaguar syno.
