Eggs identification

[TankCla]

When I got home from work, I saw these on my front glass.


I am curious, these eggs could come from nassarius or trochus snail? These are the only snails in my tank.
Do they look familiar to you?

Should be eggs from a Nassarius sp.

Interesting! They only have 1 week in my tank. I take this as a good sign.
Do you know the incubation period?

 

[Sugar Magnolia]

They won't hatch.

 

[TankCla]

They won't hatch.

Why? Explain, please!

I've had several snails in my tank lay eggs. Cerith snails and nerite snails lay them all the time for me. They all hatch to planktonic larvae, and the odds of them surviving are very slim due to the other tank inhabitants, the filtration, the pumps, bumping into things like rock or walls, etc. Very fragile little creatures.
