Pearlscale Butterfly question

[leafyseadragon]

I saw a rather nice looking Pearlscale Butterfly at the LFS yesterday, but managed to resist the temptation of an impulse purchase.

I have a 37 gallon without any fish in it at the moment. It does have hermit crabs, cleaner shrimp, mushroom corals, star polyps, and a devil's hand leather though.

What I'd like to know is if the tank is too small for just this one fish. And secondly, will it eat my corals?

I'd pass on the Pearlscale, sorry. They can up grow to 6 inches, and require more swimming room than your tank can offer. Not exactly reef safe either. Will likely munch down your polyps.
