Bumblebee Catfish?

[SunnShadow]

Does anyone have any information on Bumblebee catfish?  Are they aggressive? (could they be kept in a 20 gallon with a betta?)  How big do they get?
I saw one at my LFS and found it very attractive, but wanted to find out more about them before I attempt to add one to my 20 gallon.

Is it this one?



This one?



Or maybe this one?

The second one.... the "Microglanis iheringi," South African bumblebee catfish. I guess I'll have to research them more, to make sure there wouldn't be any danger to my other fish.
