Hi John,

I've noticed that gray treefrogs vary a great deal in personality...some follow you right out of the tank, others shy. I raised a large group from eggs some years ago...amazing how different they all were.

Unless well adjusted to tong feeding, most gray and other treefrogs tend not to go for meal worms, earthworms...perhaps not the right "look", given where they usually find food. I've found that they usually respond very vigorously to moths, flies and other flying insects, also meal worm beetles and other beetles, roaches as others have mentioned. When I had a large group (zoo) i left insects in overnight for the shyer individuals...placed wax worms in cups wired to branches. Small live silkworms always a favorite, canned accepted by tong-feeders.

Good luck, best, Frank
