Lrrr will do the same thing to Glurmo if I let him. What I do is I use two tupperware containers that fit in the tank. I manually put Glurmo in one with his crickets and put the lid on it so Lrr can't steal them. Lrrr isn't fond of being picked up and he's the more active of the two so I just let him get in and eat on his own. This way I know who is eating what.
