Being the clownfish connoisseur that i am..LOL.. I'd suggest you read Joyce Wilkerson's book "Clownfish". In my opinion, it is the most complete book about clownfish and their breeding habits. It shows you how to care for them before they hatch. I had a gorgeous pair of Onyx that where in the mating stages when they died. Saddest day in my life :(.

Best of luck to you.

If you have any questions, i'd be happy to help you.
