Thanks for the update. Really enjoy these fish. I'm looking to grab another one soon for my new build. Hopefully yours does ok back in the 4500 gallon. While yours seems to be fighting out of its weight class with the piraiba, mine never really took much flack from tankmates.
We put away 1.5' mullet yesterday - 4 apurensis
- Thread starter thebiggerthebetter
- Start date
So far so good back in the 4500 gal. Back to its normal self in about 2 weeks.
The peer who knows the most about apurensis interaction with tank mates appears to be the SharpToothBass, per his thread dedicated to this fish.

My first thread on our first apurensis from 11 years ago, 2010, with the most excellent input from Yellowcat and other experts (never mind some filler conversation on the max size, it's old news now, it has been corrected a few years back and the max size hopefully will be corrected (upped) again in the future): https://www.planetcatfish.com/forum/viewtopic.php?f=7&t=30284

Photoshoot from back in 2010-2011 - our first 3 apurensis:
-one has more yellow, our first,
- the second is almost black, and
- the third one is in between.
The arrival of our very first apu, 10"-12", from River Wonders. We didn't even know if it was safe to place it in the pond (would it eat anyone? would it get eaten?), so kept it in this makeshift temp enclosure for a day while being advised on Planet Catfish by peers:

I love these guys! Yeah, yeah, I know...cichlids are genius fish with sparkling personalities and make the best "wet pets"...but catfish have always been my favourite family and the jellies lead the pack. Mine is just starting to put on that plump blimp-like body shape that is so charming. He'll be my only "monster" fish; I just ordered the glass for his future home. 
Our singleton apu continues to do well in the 4500 gal. Likes her corner. Comes up to the front glass to stand vertically right at the surface to do its scary feeding routine with loud and violent gulps. Looks definitely over 2 feet and the girth is unbelievable. Occasional tatter of the very end of the tail is probably still the work of the 4.5' piraiba tasting it once a month to make sure it is still unswallowable.

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. I had 2 nigricaudus from a supplier many years ago. I may have the photos someplace. They were gluttons.

Nope, not mine, or at least not anymore. I had the pleasure of owning that fish for about 10 years but passed it on when I moved. It went through 3 sets of hands after mine before perishing. During the final two decadee of its life (!) It only grew about 4 inches, so probably safe to say that 28 inches is very close to maximum for this species.
My new one is just approaching the 12-inch mark (the size of that first one when I got it) so based on the previous fish, this one will hit 28 inches on my 95th birthday...

Coming into the discussion a few years late. Don't think you can poison fish from freezer burn but a lot of frozen uncooked shrimp/prawns for human consumption get a rinse in formalin bath which greatly slows them turning black to improve their shelf life. Humans remove prawn shells when eating and can tolerate low levels of formalin (relative to our size).
Luckily formalin is relatively water soluble so if your feeding fish with raw frozen prawns with shell kept on, soak in large dilution volume for 15 minutes then rinse.
Viktor,
Love those jelly (orange) cats. I'm definitely to visit you one of these days. Would be great to hormone induce /breed them. I'm sure baby orange cats are even cuter.

A wonderful educational post #44 from Yellowcat on the coloration of Pseudopim catfish Batrochoglanis and L. fowleri and fish in general: https://www.monsterfishkeepers.com/...pure-jelly-catfish.745140/page-5#post-8401811
