Snail ID?

[AquariumDani]

Photos are attached. What are these snails called? I went to the LFS today and told her I had a light dusting of blown algae, probably not actually a light dusting now that I think of it - probably needed more than 4 snails. Unsure. I guess they won't go hungry at least.

The top picture is a trochus snail I have had very good luck with them cleaning everything but you need to have lots of algae afterwards to keep them alive.

The second snail is a Nassarius snail they like to chill out underneath the substrate unless you feed your tank then they will come up out of your substrate.

The third one I'm not quite sure others will be chiming and soon it might possibly be an Astra but please don't quote me on that

Oh I see, I thought there were 2 of each kind. The lady took 2 from 1 tank and 2 from another tank.

I'm thinking two astrea and one nassarius.

I'm sorry.. I did not zoom in on the third one....

Second picture is definitely a nassaurus snail. But to figure out whether the first and third are trochus or Astrea take one knock it over on its side or on its top and see if it flips itself over if it does it's a trochus if it just stays there forever then it is an Astrea

 

[AquariumDani]

The lady did say they're not good at turning over, so I assume they are Astrea

Astrea and nassarius.

is this a mexican turbo snail? this seems to have legs and launch itself instead of gliding?
