Can Terrariums Be Too Full For Feeding? Anole Help!?

I just got 2 anoles. I set up a fine coco substrate. I added a medium sized wood hidout. 2 big plants. a kidney waterbowl. 3 sticks. Some dragon moss. and some scattered rocks. Its kind of busy and spacious on the leafs but down below not very. Today when I was feeding them for the first time I dropped in 3 crickets just to see what happened. One died. The other two scattered. 6 Hours later I saw one cricket hiding in a corner under a leaf. Will the anoles find it later or is the terrerium too big? Should I clear out the coco substrate and add a line, less plants, and less everything else? Or should I just feed them with tweezers? Please Help!
