Arrow Crab????

I have a question about an invert only tank. Would an arrow crab be ok in a 5.5 gallon. Filtration is great(filter made for a 30 g) and would i be able to keep him with other inverts?? Please comment

im not sure, try searching some info on them, google tankmates that work
Instead of one i would just have a few shrimp and a small fish
 
what kind of shrimp should i put in there, i have looked at sexy shrimp,but it says they like to hide in corals(i only have two mushrooms in there right now). i have also looked at cleaner shrimp, but i was told it might be to big for the tank. My brother doesnt want a coral banded shrimp, so thats out. I dont really know?!
