Hey guys, just an update.

I tried Don's bowl idea and it worked beautifully, at least this time. At first I was worried that the bowl I had was too deep, so I buried it in the coco fiber where the water bowl was (I took it out as there is not a lot of space in the viv on the ground otherwise) and tilted it slightly toward the inside of the viv. I was worried at first that the crickets would escape but they didn't, they just slid around in the bowl until Bruce found them (I think he was confused by the bowl at first but eventually he caught on). He ate all three and then went on his marry way, I even found a congratulatory poop! (This is exciting because Bruce was recently constipated, for those who are confused.)

Thanks Don, I think I'm going to be using the bowl from now on, worked like a charm and the crickets were helpless. XD
