Snail eggs?

[dsmitchell]

I have about 6 blackfoot snails that were milking up my water a few weeks ago -- which required a significant water change, thank you snails.

Anyway, this morning I notice one of those snails releasing something into the water a little more solid. It's everywhere. Are these snail eggs?

My chromis are constantly eating them up like cyclopeze. But the tangs, clownfish, and cardinals seem to be ignoring them. Is this safe for them to eat?

And does this mean I'm about to have a million blackfoot snails in my tank? Maybe I should be thankful for having 9 chromis right now...

Thanks,
David
