Okay. Well, I'll just let them do their own thing. Yoki was very dull when I got him, but in the week since, his colour has become more defined and his pattern is more evident. Pip looks the same to me. Another quick question: I saw a video on Youtube that stated if you overfeed these little frogs, they will throw up. How much is too much food? I'm following advice to feed them every other day and I usually give them two-three 3 week crickets and two small mealworms. I have not seen anyone throw up, but then the question is am I underfeeding them by only feeding them every other day? Thanks in advance!
