Feeding Daphnia

[ax]

It's been 2/3 days since 1st egg hatched, 3 more hatched since then so 1/2 days old... I have them in take away tubs, 3 in each and I put in some daphnia but they don't seem to be eating it... been watching for about half an hour looking for the "hopping" but nothing... I have BBS for backup in case these dont work, also do you have to do water changes with daphnia and hour or so after feeding or just regularly?
Thanks

Give them a few days. If you're keeping them very cool, it could take a couple of days for the yolk sac to be absorbed. Also, make sure your daphnia are small enough. The larvae won't go after food that's too big.

Daphnia don't die in fresh water (like brine shrimp do), so you don't need to vacuum them out since they won't foul the water. Just do regular water changes.
