Fry Log Day 2

Today the day 2 of my fry just hatched.. at about 5pm. 1-3 fries were free swimming, tried fed with live bbs, only one were eating.. =(
2-3fries dead probably due to water depth too high for it to take his first breathe..
9:30pm, fed 2nd round of bbs, a few number were nipping on them. But still lots of uneaten BBS even thou i had fed even less amount..

Points to learn: Should have kept water depth 4inches and below; concentrated bbs probably 1-2drops will be more than enough..
