Volcano Shrmp?

I highly doubt that you'd have that problem. For anything except aiptasia, you have to specifically try to succeed at reproducing them. Eggs/larvae get eaten long before they have a chance to grow up. The way that I always look at it is if you get something to breed in your tank it's a nice little bonus of free food for the critters.

That all said, I have no personal experience with these guys, so take what I just said with a grain of salt.
