I have not seen any local stores carrying that particular species, however most will place special orders for fish if they can get it through their suppliers. I do know that most of the stores use different suppliers as well so your best bet is to ask a few of them to order one for you.
Neptunes, Fish Palace, and Premier Fish and Reef all do special orders. I am not sure if the others do or not, but I am pretty sure they would as well.
Wish I could have been more help.
