Cerith Snail Eggs

So I added 2 Cerith snails Friday night and they went into hiding together, last night I see this one on this rock, did not think too much of it but it was just going back and forth along the same ridge.......well about 11am today I see some eggs; so now I am like ok how many will it lay.....well 2hrs later here is what it left behind.......Now I wonder how long before they become fish food LOL

 

Probably will be gone by tomorrow or the next day.
