New Lima catfish thread and updates

  • We are currently upgrading MFK. thanks! -neo
This depends on the exact ID. IME and IMO, vast majority of the people thinking they are buying a Sorubim lima 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.

The commonly cited rule of thumb is that your tank should be 4xL by 2xL by 2xL, where L is the length of fish. Another rule of thumb is 1 gal per 1" of fish, but that's, I believe, for small fish and small tanks.

Sorubims are quite skinny. 1' RTC weighs ~10 times more than 1' Sorubim.

I concur the advice for a group. They are better behaved and spectacular in a group. I'd recommend 5-6.

Good luck, mate. You will need it. 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.
 
So, it;s been a month. How is he?
