I have a 40 gal reef tank that I have recently devoted to breeding my pair of ocelaris clowns. There is a royal grama and an algea blenny in the tank with them. Everyone gets along fine and I have been starting to see some spawning behavior. My question is about some inverts.

I have 12 super tongan nassaurius snails, and a few bristle worms floating around. Will either of these pose a threat to my clownfish eggs?

thanks
