Hard to tell without a pic but are you sure they are clownfish or snail eggs. What do they look like? Either way if there is other livestock in there it will end up as fish food. Hopefully some can make it.
Not 100% but it does look like clown fish eggs. You might want to do a search on the site here on them as they need specialized care when they hatch. I`ve never done it but I have read several threads on it.
