Beautiful fish! Do you know the scientific designation?
I had one of those many years ago; just happened to be in a LFS when a fellow brought it in to re-home it. They didn't want it; I did. Paid for a few small fish that the guy wanted in the shop and took the monster home (around 14 inches at the time). It lived for many years in a large-fish community I had. Like you say, if it could eat something it would...but if it couldn't it never bothered the other fish. I would love to know the species name...anybody?
edited to add: Is "jellycat" actually the accepted common name? I thought you just coined it for this thread?
My wife christened it the Lump of Fecal Matter Catfish...she actually used a shortened form of that...and that's what we called him...
edited again: Holy Smokes! I looked up Jelly Catfish and found it immediately; either Pseudopimelodus apurensis or Cephalosilurus apurensis. MFK comes through again; now I want another one.
Way to go, JJohn! Yes, Cephalosilurus apurensis from Venezuela and the Orinoco river. Easy. We never get to see fowleri or nigricaudus or the forth one.
Lol, when I read the OP my first thought was "jellycat...that's a good made-up nickname! Family-friendly too, much better than Lump-of-youknowwhat!" A moment later I thought "Hey...wait a sec...maybe that's really what they're called??"
