Here is what I have done with mine since he was little (now he is a full grown adult) I have a 4.75 inch ceramic bowl like this https://www.chewy.com/ethical-pet-st...Bowls%20Diners and put a few dusted Dubias in it and it and put it down in it's enclosure, soon as he sees that dish he know what that mean goes down and eat what he want and usually finish up the rest late., I do the same for my Garg which are lazy hunters to start with and usually do not care about bugs, but mine does so long they are contained and the dish cannot be tipped over.I have a decent sized holding container for him and I wonder if for feeding insects it makes sense to put him in their with them and let him go to town? I've seen people do that with beardies. Any thoughts? I figure it can't hurt to try.
