Welcome to the group. Were in Utah are you located?
Yes, the babies will get eaten if left in the tank. If you are serious about raising clownfish babies, you need to get the clownfish book by Joyce Wilkerson - it will tell you everything you need to know about raising clownfish babies.
You need to know that in order to raise the babies, you also need to grow your own phytoplankton, rotifers and brine shrimp. It's not something you get into half-heartedly. Good luck.
