Why do you have to wait to add coral? Actually, rather than waiting for a response...
...Coral add very little to your bioload. Fish add a lot. You say you have to wait to add coral...when in reality, fish are at the highest risk if your tank is not cycled.
If your tank IS cycled, add coral tomorrow. If your tank is NOT cycled, you are at risk of stressing / killing those cool clowns.
Patience. Without it, the animals are going to suffer, and so is your wallet.
