Trapdoor snails

[Patfish]

Few weeks ago I got a piece of plant from a wild pond and put it in a jar to watch it grow and see if it would look good in my pond. (Anacharis I think)
I took a net to my pond and found a trapdoor snail to put in the jar to clean the plant. After a while I put a second in.
Today I looked in the jar and see about 24 tiny snails crusing around.
Do trapdoors have that many in one shot?
I know mine have had babies in the pond but didn't know that many at a time.
They are too small to really identify yet but I didn't see anything on the plants that would be snail eggs so I'm pretty sure they are trapdoors.
I may have to rehome these little guys.

This site says they can give birth to anywhere from 6 to 20. Just be sure they actually are trapdoors, though.

Why re-home? How big is your pond?

850 gallons I think
I put 7 adults in there last year and have seen several babies already. The ones in this jar are offspring from last year. Im not sure about putting this two dozen in with.

Im reading other posts about trapdoors. Lot of people get big ones if they can. If they only live 3 years and my offspring from last year are medium size and having babies. Maybe that is why some peoples dont last long...they are at the end of their life cycle when they get them.

I took these of 2 of my snails a few years back. Girls have equal-length antenna.

I am pretty sure now that the new baby snales are not trapdoors. they are too small and under magnification the shape is more elongated and not the right shape. this is why i put the plants from the wild pond in a jar first. just in case of tagalongs (and not the good kind)

I am going to try to snip some of the new growth from the plant and start over with the jar setup. maybe I can eliminate the unknown snales.
