Arrow crab in my 29G?

[AC2020x]

Hey, would an arrow crab be safe in my 29G reef? I have 2 misbar clowns and a firefish. Then corals- mainly polyps- and a piece of montipora digitata. Would it be safe with all of these things? Also would I just feed it regular frozen food?
Thanks a ton!!!

the can be a little nippy with some other inverts... usually all motile IME (except for feather dusters)

unless you have a bunch of stuff you're not telling... it should work fine

they are okay but you have to be cautious with them if you have any feather duster's and gobies as I noticed they like to attack them during the night.
