Fishfolk Blackboard

I currently had a mated pair of lyretail Chromis laying eggs in a 55 gallon ecosystem. I am set-up as a lagoon but since I am not educated in fish breeding, I am looking for information that will help me to go thru this and keep the fry (s) alive. myE-mail address is bubplarry@hotmail.com for any information that I can use . Thank-you
