Update: Its been two weeks now. All but 3 having been eating a mixture of pinky and worm pieces. Only one of the three picky eaters is noticeably smaller, the other two look healthy (so maybe they ate once before). Unfortunately one of these 3 is an albino. I put these 3 in a separate tank to ensure they would have a fair chance at the food. Tonight I placed some live fish in a shallow dish, but no luck yet.

Also, I have not seen any of them shed. Makes me think they shed right after birth, but I never saw the sheds.
