Do you have some sort of stock list? What other fish are there? What are your hours and are the hybrid rays you have now half price? Or is the sale limited to certain fish?
Just in case this might push someone one way or another, having personally been to Crystal Clear, their stock is generally pretty varied and interesting. Everything is usually healthy and they're upfront about it if they think something isn't. I can't comment on their SW selection. Also, they're closed on Tuesdays.
