I am not totally sure what i was doing when i stumbled upon this in an internet search but i was wondering if anyone has any of these? If so i would love to see some pics especially of some large ones. They are pretty cool cats and i would love to get my hands on one or two. Ive never seen them for sale and hadnt heard of them til 2 days ago. Looks like a cooler version of the tiger shovelnose.
 
I am not the one you wanna hear from since I've never had them but thought I'd drop my $0.02.

They are not common but not very rare. Not too expensive. A 1' one would set you back $150-$250 in the USA. They are far more slender built than a TSN (and are from a different genus) and in the wild they are a very specialized feeder feeding on nekton. My understanding is that in captivity they take the usual foods large Pimelodidae take. Here are some data:

Firewood Catfish Sorubimichthys planiceps, Brazilian local name, sorubim + Greek, ichthys = fish.
Siluriformes > Pimelodidae
FishBase: max 150 cm SL.
FWR: max 145-200 cm; 16-50+ kg.

As you can see, they can be very long but weigh relatively little as they are thin.

Freshwat.; demersal
Tropical
South America: Amazon & Orinoco River basins.
Mainly nocturnal. Feeds primarily on nekton. Fisheries: minor com; aquar.: P.A.

From Wikipedia: http://en.wikipedia.org/wiki/Nekton

Nekton refers to the aggregate of actively swimming aquatic organisms in a body of water (usually oceans or lakes) able to move independently of water currents.

Nekton can be contrasted with plankton which refers to the aggregate of passively floating, drifting, or somewhat motile organisms occurring in a body of water, primarily tiny algae and bacteria, small eggs and larvae of marine organisms, and protozoa and other minute predators.

As a guideline, nekton are larger and tend to swim largely at biologically high Reynolds numbers (>10^3 and up beyond 10^9), where inertial flows are the rule, and eddies (vortices) are easily shed. Plankton, on the other hand, are small and, if they swim at all, do so at biologically low Reynolds numbers (0.001 to 10), where the viscous behavior of water dominates, and reversible flows are the rule. Organisms such as jellyfish and others are considered plankton when they are very small and swim at low Reynolds numbers, and considered nekton as they grow large enough to swim at high Reynolds numbers. Many animals considered classic examples of nekton (e.g., Mola mola, squid, marlin) start out life as tiny members of the plankton and gradually transition to nekton as they grow.
 
I had one in the past, got it around 18". Sold it shortly afterwards because it was getting beat up by it's tankmates. I didn't find it anywhere near as predatory as some of the other larger pims. I haven't found them to be too common locally. This was only one of two that I have seen locally.

Is there something in particular you were wondering?
 
i have one at about 22" he is a sweet heart lol dosent realy bother any of it tank mates but is a nasty feeder lol i love mine but from what i can tell thay are hard to come by at lfs but not to bad for online order.

Well not so much anything in particular, i just want to know everything. Basically i was wondering if it could be housed with other large cats(if i found one) but i dont think i want to try to find one. Dont want to make it its own big tank and i get the feeling my RTCs or RTC/TSN hybrid would not be good tank mates. Its just a cool catfish i have never seen and know very little about so i was trying to get some personal experiences etc.

I usually watch aquabid a lot. I will have to pay closer attention to the catfish section. I have never kept any pims, what types of food does this species eat in captivity? and would it be ok to house with my other cats or should i have a separate tank for it?
 
Most of the ones I've seen were on MFK marketplace. Rarely aquabid. Mine is about 1' and resides with my other cats. Still a little rough looking from shipping and ich treatment or I'd post a pic. Has shown no aggression but attacks krill and sardines as soon as they hit the bottom.
