Not feeding

I have a few new adult and juvenile Gargoyle Geckos each housed individually in 12 x 12 x 24 cages with lots of sticks, fake plants, and a feeding ledge with food and water cups.

My problem is I don't think that they are eating the food (Pangea, 2 different flavors). Each night when I feed them it does not appear that they are eating any of it and it eventually dries up and is thrown away. However, if I put food on a spoon or stick in front of them, they all readily lick it up.

Any tips on getting them to find and use their food bowl? Just don't want to have to hand feed them forever.

Thanks, Dave

ive been having the same problem lately with my adult garg that ive had for a year. interested to see what it might be

Is it possible that they are eating but you cannot notice the difference in amount of food? Same goes for my crestie. Every once in a while I will notice she has eaten some, but other times it seems she hasn't. But she isn't losing any weight and her calcium sacs are healthy so I must assume she is eating.
