You have the largest type that grows to 61in. you can tell the difference when yours gets bigger than 8in. B. bargarius only gets 8in and B. suchus only gets 28in.
Okay, for real, the bagarius has the pelvic fin starting in front of the base of the last dorsal ray and the adipose fin starts behind the origin of the anal fin.
The yarelli's pelvic fin starts behind the base of the last dorsal ray and the adipose fin starts in front of or level with the origin of the anal fin.
, the kisser was a good one , thanks for d input guys. for a minute i wish it was a B.bagarius , it doesnt make a good tankmate rite, currently hes 6inchs.
I know the B. yarelli doesn't do to well with tank mates. I don't know about the B. bagarius. Since they only get around 8in so you might be able to keep somethig with it.
