phoenix worms are my new favorite thing for baby frogs and turtles.. they look like tiny waxworms and are supposed to be very high in calcium... my clown treefrogs love them and they are around the size of baby green treefrogs..
i havent ever had problems with young frogs eating.. are you feeding them at night? the best way (IMO) to go about this is put pinhead or 2 week old crickets in a deli cup in the tank before you turn out the lights ... the crickets cant hide from the frogs and you can tell whether they are eating them or not..
