I go to Eddies Aquarium in Latham - they are on Route 9 a little North of Guptil's roller skating arena. Most of the staff appear to be very knowledgeable - they have started running classes. I've been going to their store for about 20 years - first with birds when they were in Menands and they have moved twice since then. My salt water tank is only two months old, but doing very nicely with their help as well as everyone from the swf message boards.
