i have them in deli cups with an inch of sand and feeding them 2 pin heads a week. i'd like to know if their's anything else i should do. when should they get their 1st molt? when can i move them to a tank?they're still white. i've already lost about 10 all together right after moving them. i've got a lot left still. if i can get some fast info on care for young from u guys, i'd appreciate it.
