Astrea vs. Trochus?

[Raibaru]

Sup guys, I'm going to replenish my clean-up crew over the weekend and I'm not sure which of these was the one you should avoid because they can't right themselves after they fall over. If someone could let me know, I'd appreciate it.

I plan to buy
10 sm. Nassarius Snails
10 Cerith Snails
5 Astrea (or Trochus) Snails
1 Turbo Snails

Anything you think I should add to this list?

Thanks folks!

its the trochus that right themselves.

Astrea can't right themselves.

I like the trochus simply because I can drop them in and not worry about them

Some species of trochus are also known to breed in aquaria, way better than Astraea IMO.
