I had a group of them. They are the most entertaining fish ever. They will eat any food you give them, mine hand fed and went nuts every time my hands were in the tank. Awesome fish!
What I found most interesting about them was they're adaptable species that can be found in a wide range of biotopes and can even tolerate hypoxic conditions. It can thrive in anything from a flowing stream to an oxygen-starved swamp.
I had a school of 6, one of the coolest catfish I have ever owned very very peaceful and active. and as stated before will eat just about anything and any amount of it as well, you should get him some pals
