At my work I've seen a 2inch one beat up a 6 inch Jardini. until the Jardinis fins got so bad we moved it to its own tank. They also are able to hold their ground at any size against full grown oscars and managuense cichlids.

I seem to be the oddball. Everyone I kept wasn't a issue. They were like blochii for me.

You know better than me :) It's not described as a nuisance fish in a community for nothing.

I seem to be the oddball.
And have a knack for stating the obvious. :)

Seriously, thanks, Moe. I am glad to learn of exceptions. The nature of their tank mates is of crucial importance, it would seem. You likely merely lucked out without knowing it ;)

I do consider the fact I always had wolves or cichlids with them. With the wolves my experience was as expected each time, wolves always give anything new a nip ime, usually all it takes then the two ignore eachother. With my curu only the wyckii and odoe fought back from everything I kept with it. With cichlids, the USD cat held his own with them, namely buttikoferi, jag cichlid, jack Dempsey, Texas, red devil, and I'm sure I'm forgetting some, at different times ofcourse, most specimens (of the cats) grew to around 8" for me then slowed. The only cichlids that got 10"+ with them were jaguar cichlid and buttikoferi. The others were of equal length but more mass generally. And it stuck to it self mostly when confronted it would flap its body a little and that's was the extent of what occurred. All at different times in my 120. Makes me realize how long I've had this one tank. Lol

Fifteen month update. The AUSD catfish has been doing well. Perhaps currently around a foot. A glimpse can be seen here from 50 sec to 60 sec. Most usually it spends 99% of the time upside down, duh, under the pump outlet pipe at the top but because the tank light is on (I have been using it exceedingly seldomly), it is not.

This thread is, of course, about a different USD catfish, Asian USD catfish aka Mystus leucophasis. My thread on synodontis, including three S. eupterus aka feather fins is here: https://www.monsterfishkeepers.com/forums/threads/synodontis-quartet-8-12-in-4500-gal.682549/ Both can be unpredictably aggressive, I agree.
