Sorry not part of the group but I am from Albany. I would check out Healthy Pets in east Greenbush. Also Upstate Corals in Schenectady is a pretty new shop in the area, haven't been there since they first opened, they looked like they were going to have a alright setup.
Maximum Reef was mentioned, I have made the 2 hour trip to that store several times because it was worth it. Their prices are better than online prices. 85 for medium purple tangs.
