I dont recall Aquarium Stock, but there are a few shops i wish were still around. Crystal Aquarium on 93rd St. And 3rd. Ave was a young fishkeepers heaven, rows upon rows of quality livestock. There was another huge store on 23rd street on the east side that also had beautiful quality fish. They had a huge saltwater and reef section also. My favorite shop by far was Trailers Tropicals on Gun Hill Road in the Bronx. This was a little hole in the wall mom and pop store, but this is where i became a fishkeeper. Would go there for a few hours after school everyday and learned everything i could from the owner John. I would catch garter snakes back then and trade them in for fish. Eventually i started asking for more exotic stuff and John asked me if i wanted to go with him to the wholesalers place and i could pick out my own fish. Thats all it took, i've been addicted ever since. Wish these stores were still around.
Crystal was great too! 93rd and 3rd right on the corner.
