Question about snails laying eggs

[meganias123]

Before a month or so ago, I had never seen any of my snails lay eggs or any evidence that indicated they had (i.e. eggs). Within the past month my nassarius snail has been laying eggs - three batches now(one batch, three separate times)! I have three nassarius but only one of them is doing this. I read that it could be an excess of nutrients or something... but these are nassarius snails - carnivores - and I haven't had any of my fish, snails, shrimp, etc die...
The first time it happened was when I got back from a trip and found out my tank babysitters had been overfeeding (maybe that contributed). However, the over feeding has stopped since then and the tank has had 2 good water changes and cleanings.
Anyone have any idea what is making my nassarius do this?
... I'm not really wanting a tank full of nassarius snails dying off because there isn't enough for them to eat (or me overfeeding to support them later). [emoji20]

So my nassarius snail just finished laying 3 sets of eggs over a week period. Do you have any updates? I'm curious to what happened. Fish food? Or do you have tons of snails crawling around?
Thanks!

Actually the eggs just stayed there... never saw them hatch and i haven't seen any tiny snails moving about (besides the colonistas). When I would do a water change most of them would disappear...
The same nassarius is back at it again laying eggs this very moment (I did a water change last night and she crawled up to the side and began shortly after the change). She has done this many times since then... I just don't worry about it as I did when I posted this because I've never seen any hatching/etc.
Also wanted to mention that sometimes - for some sw critters - it takes a slightly higher temp to get eggs to process and hatch and my tank stays around the lower temp parameters.
Sorry for the long response... I'm a very drawn out speaker xP
