Are there species of available anywhere that are not very active and kind of stay on the bottom of the tank a lot so a non active catfish species
I didn’t see my Niger move for about 2 months. One time he stayed next to a heater in a holding tank for almost a day left a nasty burn on him. Yah you want a log Niger is a way to go
They don’t get active till they get bigger. My irwinis and granulated constantly zip through the tankTrachy trachy, lithodoras dorsalis, pterodoras granulosus & irwini. These cats literally logs & they can grow huge but still stays under 4'. I could suggest ripsaw catfish but they are quite active than most people think.
