Help, Melanotaenia Praecox Fry Need Help Raising Them

[garuf]

Hello, I recently had a co2 burst killing everything in my tank, or so I thought. Today I was doing maintenance and I noticed there's about 30 rainbow fry swimming about just below the surface.
Is there anything I need to do to feed them or to raise them? they seem strong and healthy and are coping with the current with ease.
Help I don't want to lose any more fish.

These are quite easy to rear, you need some tiny foods at first, green water will help supply this if you can get some.

However the best foods is newly hatched brine shrimp.
You can buy these from ebay and only take 24 hours to hatch, feed it from about 5 days old and the largest fry may just be able to eat it, if you can get green water the feed brine shrimp from day 8 or 10

What's the situation regarding water changes? same as usual? (50% a week) or do I go reduced or what?

do slow water changes of onlt 20-30% at the most.
