Harlequin compatibility

Does anyone have any advice on the compatibility of Harlequin shrimp and Fire shrimp? I would like to put them together in a 29g Biocube, but I don't want a duel.

They will be fine together as long as they're introduced at close to the same size. Fire shrimp can be a little aggressive, but they generally don't bother Harlequins, IME, as they don't compete for the same food.
I have a skunk cleaner which is bigger than my Harlequin, and it will occaisionally go after the Harlequin's starfish. She has no problem chasing the cleaner away. If not at the same time, I would introduce the Harlequin first.
I don't want to make assumptions, so forgive me if you already know this, but you're aware that all Harlequins will eat is live starfish (of the non-serpent variety), correct?

Thanks for the advice. I have had the Harlequin for about two years, and I generally feed him chocolate chips stars. I have had the fire shrimp for 6 months or so in a separate tank. I want to put the fire shrimp in the same tank as the Harlequin, and the Harlequin is a little smaller than the fire shrimp, but they are of similar size.
As per your experience I will try the merge and see what happens.
