Newly hatched fry

I have just managed to pair up a blue silver female with a blue smokey male.  The male I got from Rob back in march.  There are about 40 wiggley blue fry attached onto a leaf which both parents are tending to. They are in a 100l tank.  This is my first brood so im not expecting success but obviously want to give them every chance.
I'd really appreciate some advice.
When do I need to start to feed them?  They still seem to have their yolk sacs and are about 2-3 days old.  What do I feed them?   I'm assuming baby brine shrimp.  How do I feed them?  Also is it ok to do a water change?  Also the glass is now covered in algae. Can I clean the glass without disturbing and spooking mum and dad.

This is mum and dads second spawning. They ate the fry as they were hatching

Many thanks in advance

Hi Justin,
Congratulations.
Feed newly hatch brine shrimp, but only once they go free swimming, usually on the 7th day after the eggs were laid, here's a thread on hatching/feeding bbs http://www.uk-angelfishforum.org.uk/t337-how-to-hatch-brine-shrimp
personally I wouldn't worry about the algae, or water changes, at least until the babies are free swimming and the parents are clearly guarding them confidently.

Much appreciated Rob
They are now free swimming. I have about 40 or so
Mum and dad seem to be taking good care of them and are keeping them together. Dad in particular seems to watch them carefully and will return any too adventurous fry back to the main shoal
The only baby brine shrimp I can get right now is frozen. It forms a fine powder in the water and they do seem to be taking it
I could not resist cleaning a portion of the algae off the glass so I could watch them. As It turned out they also ate the algae and also seem to be eating very small worms that are also on the algae

If they're eating it, that's a good sign, just take care not to overfeed, at this stage they need really tiny amounts! It's much easier to kill by overfeeding than through starvation!
