Banjo Catfish

I've really wanted one of these for quite some time and am just wondering everyone else's opinions on them or if anyone has any experience with them. I've read that they are carnivores like a lot of other fish, are bottom dwellers of course, pretty shy, can get to around 6", etc.

Just a reminder of what's in my 36 gal bowfront tank:
  • ~10cardinals (3")
  • 10-14rummy nose (3")
  • shrimp
  • 4 kuhlis
  • galaxy guppy, his kids (right now there are 10 fry in there and 4 fry that are grown up a bit, no they aren't all staying in the tank I'm just waiting for them to get larger to see which ones I want to keep in there [maybe like 4 total tops])
  • one random fish, i seriously need to figure out what it is
(and I promise I will attempt to count my cardinals and rummy's better, I've been slacking on counting them!)

the Kuhli's the main guys at the bottom, so I'd mostly be wondering how they'd interact.

Thanks in advance~
