So I want to feed based on their stomach size as their eating? How can I keep the piggy from hogging the food? He finds it immediately, it takes the albino a couple minutes. Is that because albinos don't have as good eyesight? Also, I'm not sure of their age, they are amplexing (is that right?) but they are only 2" not counting legs. I thought males got up to 3-4"? So I've been assuming their not quite fully grown. Thanks a lot for your help!
