I've never seen goldfish at total aquariums, they specialize in saltwater and find their fresh selection to be very poor. Aquahut in coram has a large selection of goldfish toward the back part of the shop in their cold water section. Also country critters has goldfish area located right before their main fish room. Aquarium village has a poor selection in fresh. I don't know too many good fresh water stores in nassau but the salt is great. Not sure about Caribbean blue aquatics along sunrise and jbj tropicals. You can also call pets warehouse in carle place they have a row of tanks dedicated to goldfish
