What kinds of snails are these?

[Zionas]

Pictures from my Chinese LFS. Can someone help me identify what kinds of snails they are and what kind of algae / detritus / uneaten food they take care of? Thanks.

1- Trochus/turbo
2- Astrea (ninja star?)

It sucks that LFS here don’t go by common scientific names for these snails. So they don’t use Trochus, Cerith, Astraea, Nassarius etc.

How many types of snails would a typical reef setup need?

Agree with @samnaz. The last one might be a virgin nerite snail. I have a variety of all the clean up critters that I’m able to find; marginella snails are my favorite and are not common.

Ahhh I see I guess I might try to get all 3 kinds

Last one looks kinda like a Lunella Coronata to me, but not certain
