Need ID

Wondering if anyone knew what this is. I have about 20 of them on my front glass, they are a clear teardrop shape with the center full of whitish balls.
Thanks,
Joe

Hi,

These are snail egg capsules produced by snails such as Nassarius (and some other species). Each capsule will contain numerous small eggs. The eggs develop within the capsules for a few days/couple of weeks, and then the capsule opens to release swimming larvae into the tanks.

The larvae are generally unable to survive long in our tanks (they get eaten by a lot of the tank inhabitants), however, occasionally reef keepers have reported some juveniles resulting from this process.

Castorpollux - I did not see any feather coming out from them, anyway, I have some tinys white spot over some zoos and I am afraid that they are the same things.
May they grow over zooanthids?
I hope they are not bad for my tank.

Thanks

what you have in you pic are in fact worms very small and wont get very big however if you have the same rams horn shape on your zoas that could be trouble those could be nudibranchs and if so that is a hole other ball of wax. How do you polyps respond have you seen anything on them other than that. Are they closed during the day ever??

Yes, I think is not to worry about calcareous worms.
About zoas they did not open up,,, and I am afraid the white spot could be nudibranch.
There is something I can do about it?
