My little Cuban tree frog became a frog a month ago. He still doesn't eat though. I have kept a piece of ripe fruit in his terrarium, so there are always fruit flies. I also keep a dish of newborn dubias (which might be too big) and super tiny mealworms. He won't eat. He's getting skinny. I took him out and put him in a critter keeper with a bunch of bugs, and still nothing. He is too small to force feed, he's the size of my thumbnail. Is there anything else I can do? I got him as a tadpole, and he ate algae wafers then with no problems.
