what kind advice are you looking for? whats your setup and clowns?
here are a few basic tips that helped me.
1. water temp should be 81 - 84. mine is 82
2. times 12 hour lighting schedule
3. feed feed feed. and different types. i feed my clowns 4x a day with a frozen concoction, pe mysis, spectrum pellets, freeze dried mysis, formula 1 pellets and sometimes flake. raw food is the best though.
these are the 3 most important basics.
you could try adding rotifers to the parent tanks and some nanno to simulate an algea bloom, and also adding bbs to the pairs might help to.
