Favourite invertebrates/cleaners

[Sarah1990]

Hi all, I'm currently trying to make a wish list for invertebrates that will be a good clean up crew when I set up my first reef tank.
I would love to know what you have in yours, what's your favourite and are there any you wouldn't add again?

I'm a big fan of astrea and cerith snails. They're long lived and eat a variety of algae.

I prefer Fire shrimp over Skunk. Skunk is notorious of stealing food from corals- IME.
Trochus and Zebra Turbo snails are also my fave.

Brittle stars, and Sally lightfoot crabs.
