Yes, these are the infamous goonch.
B. yarrelli can get 6 foot plus in the wild, and is a real tankbuster in captivity. I've seen many pics of these fish over two feet in people's tanks. These fish are also called the devil catfish for good reason, they're killers. They'll eat anything that's smaller than them and will pick apart fish that are bigger than them. But then again, I've also seen some that seem to get along fine with other fish. It may come down to the individual fish's personality and how it was raised.
B. bagarius stays under a foot long, and from what I've gathered they don't have quite as bad of an attitude as a yarrelli. The main problem of this species is that they look nearly identical to young yarrelli and rutilus, both of which can get huge.
Good luck in your search, I'm looking too!
