Trigger Question.

[OCDP]

I know most triggers are not "reef safe" And I'm having a brain fart. By saying "not reef safe" does this mean they nip corals, or do they eat all inverts?

I was thinking of maybe purchasing a small trigger locally, I was thinking along the lines of a clown, or niger trigger.

Then again, if someone knows or has any suggestions , please feel free. I am just trying to sketch out what fish to add to the new 50g cube, and I have always loved triggers.

I have snails, an anemone, and 1 Crocea clam.

(yes, Pysire's thread made me want to inquire about triggers...)
