Gold had brought some in about a year ago IIRC. So yeah, occasionally do come to town. As mentioned there's one at the N&N page at J&L, I thought maybe that's where you saw it.
Pretty fish, max size is too big for my liking though, although I kinda feel that way about most rabbitfish except for virgatus or doliatus. (For whatever reason S. doliatus is a hard beast to find locally. Been looking for one for 2.5 years now.
)
