Thousands of eggs?! What laid them?

[Grady’s_Reef]

I have so many snails in my system. The banded Trochus spawned in the water column when I first added them in spring so there are hundreds. So, I assume these aren't Trochus. How did they get the eggs in the small gap between the cleaner and glass?

My rock is filled with baby Nerite, Trochus, and a bunch I don't know because I used live rock from Fiji. I added Trochus, Nerite, Astrea, and a few Mexican Turbos

@Grady’s_Reef Those look to me a lot like Nassarius snail eggs. What snails or other invertebrates do you have?

Agree nassarius snail eggs

How many of these various snails will actually live from the eggs?

My glass is filled with various snail eggs, wondering how many of them will make it.

Not many. Most of the time fish eat them.

I do have 3 Nassarius that have somehow survived with me for years. That is most likely what they are.
