Snail Babys(Mystery Snail Babys) Turn To Nerite Snails?

[BaylorPerez]

So looking over my new hatching mystery snail eggs(2 mystery snails laid eggs), i was wondering if the hatchlings were supposed to look like nerite snails with thier shells rather han with the rounded shells with their mystery snail parents? is this normal? or will the snail shells fix themselfs to where they look like the mystery snail shell again?
 
Also with my water not being brackish how are they hatching in my cory tank(confused here) and is their any precautions i should use before i move the eggs to the breeder/medical tank?

Hi, do you have a pic? mystery snail babies look like very tiny versions of the adults so they won't look like nerites, mystery snails do not need salt water to hatch as they are freshwater only, nerites do but nerite snail eggs do not hatch into tiny versions of the adults in fact they look nothing like snails to begin with they look and act more like baby brine shrimp floating in the water, they are difficult to keep alive.

heres the 2 that have grown(probally about 2 weeks old to about 3 weeks old on both of them), there were 2 "mini"(as in to small to take a picture off or even see clearly as they were pure white)

That looks like a pond snail.

pond snail?

Often considered a pest but if their numbers are kept in check they can be beneficial as they will eat waste.  If you have lots of them then there's a lot of left over food waste in the tank as they will only breed a lot if there's food resource available.
 
Typically they come in on live plants.

so thats what the goo like substance is that was on my ornament when i did the substrate change

 

[Far_King]

Yes, no doubt snail eggs.  They'll lay just about anywhere.

 

[BaylorPerez]

Do i keep these "Goo" egg sacks? or remove them? or is this just for when the population gets to much?

 

[NickAu]

Its up to you, Snails add to the bio load in the tank but in my opinion that is not an issue as they do more good than harm, A tank without snails is not as clean as a tank with snails, If your snail population is out of control its because they have lots of food.

its funny as to why they hatched, it happened the day after i started feeding the bloodworms to my corys. even with just 1 "cube" the corys ate them up within a couple hours as they were trying to eat one with it in its gills.     Also with my cories, i did notice that today and last night they were acting very strange. (glass skimming, glass running, and when i got near the tank they scattered. Normal or just them being scarred?

And also, they were "clearing" a hole in the sand, possible breeding space?

I agree the snails are pond snails, and I agree with what others have said on them.  Very nice little helpers.
 
To the corys behaviour.  They will often charge up and down the tank glass.  With some species this is fairly frequent (my pandas do this, especially on the wall below the filter return, as this species occurs in faster-flowing water than most others) but with others it is usually a sign of mild stress, and will commonly be observed for a few days to a few weeks after being introduced to a new environment.  Nothing you can do, they will settle down on their own, but try not to further stress them.  Peace and quiet is what they need.
 
I doubt the sand excavation is spawning; corys deposit their eggs singly on surfaces like plant leaves, sometimes wood, tank walls, even filter tubes.  The excavation activity could be searching for food, or hyper-activity as they are still settling in.

ah i see, well the only fish that is making it proablly stressed is the other cory, or possibly the new snail pond inhabitants

No, the stress is not from within the tank.  The fact that the corys are new means they are under stress and need to settle.  Stress that can impact this is from you, the aquarist.  This is the case with all of us.  Give the tank as much solitude as you can.

these are the old cories that ive had
