What kind of starfish?

[badamsios]

I want to add a starfish to a tank with a clown trigger and a lion fish.

I want one that will aggressively eat left over silversides...etc. Advice?

Anything else I can add to help keep the bottom clean?

These are good for cleaning the bottom. I personally think stars would not last long with a trigger IMO.

I don't have sand, it's crushed coral. Don't those guys need sand?

I was thinking along the lines of a serpent sea star.

I personally think the trigger would make quick work of it. Yes also the CC would not work too good with the nassirus snails.
