Can anyone tell me about this catfish?

[Joshuakahan]

Hi, I have a group of hujeta and geo.sveni coming in and am thinking about adding this catfish to the mix. Unfortunately I can’t find much info on it. How big, temperament, how predatory etc would be helpful. Also my hujeta are coming in at around 3-4” and the geos around 2.5”. This catfish is listed as 4”.
thanks for any info
Im assuming it has similar parameter requirements to the other fish
Thanks for any help

I’m also considering this aluminum catfish that’s currently 4-5”. Any info on this as well is appreciated

AFAIK Piramutana piramuta is not a valid species. The name seems to be wrongly used for Megalonema platycephalum or for young Brachyplatystoma vaillantii.

Aluminium catfish are frightfully boring and almost never seem to grow much in my experience; TBTB has a thread on them, I'm pretty sure. Milingu , I've personally never heard of P. piramuta being used for B. vaillantii; is it just that few use piramuta as a trade name and that I just haven't seen many labeled as such?

Scientists did it.

Huh, never knew that. Thanks for the info!

Thanks for the input, there’s not much info around on the aluminum. For size I’m getting everything from 8”-28”. But what seems to be consistent is that they grow super slow. So after watching some videos, I decided on 3 Chrysichthys longipinnis around 3” from a different site. They look really interesting to me. Guess worst case I’ll be donating some larger fish to my local aquarium in a few years lol

The 'Piramutana pitruamuta' appears to be Exallodontus aguanai. https://www.planetcatfish.com/common/species.php?species_id=1864
