I moved my bitty adult creobroter to a small 8x8x8 exo terra, to give her plenty of room, but she didn't seem to like it. She stayed in one place for 3 days and didn't move or eat - even if the fly walked right over her. I moved her back into her 32oz cup and she immediately perked up and snatched a fly! I guess her permanent habitat will be small. I do have a few 7x4x4 rectangular acrlyic containers that I may modify. She may like that better. They'd still be on the small size, but give her a bit more room.
