i love these catfish this is one i have in a quarantine tank for the next week or 2 until i make sure he is 100% clean. I have another one about the same size as yours and hes in a grow out/guppy & ghost shrimp feeder tank.
just make sure you have a nice cave or a piece of PVC piping, they are really nice but you wont see them as much as you would like. They hate the light with a passion, and move so fast when they see the light im always afraid he will knock himself out when he rams the glass.
No in tank pics yet. I'm going to let him settle. I used to have a giant bumblebee but sold when I sold all my freshwater. I just have my lil peacock bass and this lil guy now.
