They're way to skittish to handle, and lightning fast. A top opening tank would be the way to go. Thats where i'm heading with these guys down the track, or i've had a thought of fitting in a piece of glass as a barrier about 15 or so cm tall so that when i slide open the door i don't have to stop myself from blinking to make sure they don't do a runner.
With all this in mind though, i've not yet had a problem, and they are relatively tame, when they're really hungry i can tweezer feed them...
