It's a doradiid. Doesn't look like the common ones - niger, granulosus, or irwini. I guess https://www.planetcatfish.com/common/species.php?species_id=1486 Centrodoras brachiatus
How did I know you'd get it first guess Viktor?!?! Your knowledge of catfish is amazing! Extremely impressive (if you can't tell I lurk here much more than I post).
Thanks but just a lucky guessThe reason I even know about this fish is thanks to
koltsixx and his edifying reports on it.
