My lil guy does not eat outside of his tank. He just refuses, so I have to put crickets in his tank. Problem is, they hide everywhere and fishing all of them out is a pain. I want to be able to just throw them in and leave them in there without worrying about them biting him at night. What can I build on one side of my tank to keep crickets in but allow my dragon to go in and out and feed as he pleases?
