Very nice thread. First time I see big limas. Good to read assurances that they are around.
IME and IMO, vast majority of the people thinking they are buying a Sorubim lima (in US) are actually buying a Sorubim elongatus. It is quite far from trivial to tell one from the other using their exterior. Meanwhile, the adult size is quite different, 1' for elongatus and 2' for lima.
If you care to read a small exemplary bit, take a look here. http://www.planetcatfish.com/forum/v...38&hilit=+lima
As you could see, our colleague Back (high level hobbyist) from Finland thinks the position of the mandibular barbels with respect to the gular and other skull features may be telling. I do not remember this approach having been validated by a known respected ichthyologist. Thus, I was never sure.
I still don't know what mine 7 were. They never grew beyond 11". Makes me assume they were elongatus but I have not had them long enough to be dead sure.
