Escape Proofing/deterring Dishes

Does anyone have any ideas on how to make deter superworms from escaping dishes in my Tokay enclosures? Tong feeding these guys is way too frustrating... they have these tiny stone-like dishes from flukers I think and I have lined them with packing tape which works okay when I do it for less than 3 superworms or so but the humidity gets to it after a day and then the tape pretty much isn't sticking to the dish at all and they can wiggle under it. The idiotic crickets love to jump in it after the superworms are gone though because it soaks up heat. Any ideas on how to make it more escape-proof for the superworms?


Side note update on my Tokays... Diablo and Fuega are both doing great. I've had them for 2 weeks today... they are both eating better now, I personally see them eat at least a piece of food (superworm) a day and then they free feed on the crickets. I think Diablo even looks like she's grown a bit, Fuega is still catching back up. Their color looks pretty good... the past several days Diablo was a little dark but I think she had to have shed today while I was at work because she was a really gorgeous blue when I got home... she turns it down when I look at her too long though. And Diablo's fecal test came back good.

Glass bowls or stainless steel bowl, something that is smooth and not too shallow.

I use these rabbit/guinea pig dishes, they work great!

I picked up some little stainless steal cat dishes for now. I think I will have to re-enroll in community pottery classes so I can make my own decorative feeding bowls that are smooth inside. So now my feeding tongs are just used to move the superworms to the bowls
