Welcome to GF. I have an enclosure with 1.2 gargoyles, another enclosure with a leachie and another enclosure with a crestie. I refresh their food every Mon, Wed, Fri. Frequently the food looks untouched, but they are growing and healthy. I recommend, unless you like doing it, not hand-feeding, continuing to offer food in the bowls and keep an eye on whether they continue to look the same size or are losing weight. See if they will eat crickets as well (I offer them twice a week and they all eat them except for the leachie). I bet they'll do just fine.
