Another good San Francisco LFS is called Lucky Ocean Aquarium. The manager Steve is amazing. He knows I am just a broke college student with a huge fish obsession that I struggle to pay for. He never tries to sell you something you can't afford and gives some really nice discounts. Also he has a really nice healthy cichlid selection he has F1 fontosas and some other really nice fish and plants, super affordable. I would definitely check this place out if you're in the SF area.
