If you're gonna buy from live aquaria, buy from Divers Den. Anything you buy from live aquaria (besides DD) comes from LA wholesale anyway. The good thing about them is they do guarantee for 14 days and they definitely honor it. You can even call them on day 13 or 14 if the fish happens to be sick and they will honor it if the fish dies a few days after the guarantee.
That all said, the quality hasn't been that great lately. I've had a lot of losses from them.
