Congrats! I just found my first batch too but... only 4 & half of them died already But I think that is because the mum was sick, I just wish I could have more, so cute!
I'm not very experienced in this, but what I have been doing is feeding them finely crushed flake food (wet a toothpick, dip it in the crushed food, & dip it back in the tank). From what I have heard, it's best to feed them baby brine shrimp, blood worms, etc. too, I just happen to live in the middle of nowhere & can't get any at the moment though.
