Yeah my lima and jbh's actually look a lot different as far as spotting and color his are elongatus. Both are awesome fish

Catfish for a 225 Gallon?

Ya I bought them as sorubim Limas from my lfs but they turned out being elongatus which is fine with me IMO they are pretty awesome fish. So they are maxed out. Thanx.

Hmm ok all this was really helpful. I think I'll see if I can get two. But I might order them offline and in the description all it says are Lima ShovelNose Catfish so I won't know until I have it.

AFAIK and having consulted the experts, it is nearly impossibe to tell S. lima from S. elongatus using their external features, like gular etc - here is one of my older threads trying to ID my "lima": http://www.planetcatfish.com/forum/viewtopic.php?f=13&t=30938&hilit=+elongatus
The only good way I know of is the size they max out at - elongatus 1', lima 2'.
If someone can teach/show us something more in telling lima from elongatus, that'd be well appreciated.

Thanks much, Michael. This is the revision that has been discussed.
It would appear that the position of the mandibular barbels with respect to the gular apex is the ONLY way remotely feasible for a hobbyist to ID a live fish:
Key to species of the pimelodid genus Sorubim
1 Gill rakers 3137 (Fig. 1B).........................................................................................................S. maniradii
- Gill rakers 1323 (Fig.1A, 1C).................................................................................................................... 2
2 Pectoral fin-rays 8; gill rakers on first arch modally 21; tooth patches on vomer not connected (Littmann
et al. 2001b, fig. 3b); insertion point of inner mental barbels even with or posterior to gular apex; head and
body elongate, body ovate in cross-section; eye diameter into interorbital distance 23 times; gape width
into head length more than 3.6 times..........................................................................................S. elongatus
- Pectoral fin-rays 9, rarely 8 or 10; gill rakers on first arch 18 or fewer; tooth patches on vomer fused (Littmann
et al. 2000, figs. 4a and 4c,); insertion point of inner mental barbels anterior to gular apex; head and
body stout, body moderately compressed laterally; eye diameter into interorbital distance 3 times or more;
gape width into head length approximately 3.............................................................................................. 3
3 Caudal fin with rounded lobes, distal caudal rays on upper and lower lobes curved (Fig. 2A); distributed
east of the Andes Cordillera ........................................................................................................................ 4
- Caudal fin deeply forked and elongate, distal caudal rays on upper and lower lobes nearly straight and
pointed (Fig. 2B); restricted to the Lake Maracaibo, Sinu and Magdalena River basins.......S. cuspicaudus
4 Premaxillary tooth patch greatly exposed, exposed tooth patch length about equal to width (Fig. 3C); head
triangular and spear-shaped (Fig. 3B).............................................................................. S. trigonocephalus
- Premaxillary tooth patch moderately exposed, exposed tooth patch length contained 1.5 to 2.5 times in
width (Fig. 4); head oblong, not triangular......................................................................................... S. lima
