Hi!
I just got two baby white's as well. One of them is about 1.5 times the size of the other. I know for sure that the bigger one, keahi, is eating, because i always see her around the cricket bowl (I use the glass bowl trick) when I wake up. They always have mealworms available and I've been feeding 15 crickets every 2-3 days. Both of them are active and move around the enclosure.
I have tried to monitor their eating, but they refuse to eat when I am watching them! How can I make sure that both of them are getting the food they need?
