o also i would NOT recommend ocean aquarium. their tanks are filthy and of stuff . they have a lot of guppies and stuff but i have a feeling they dont do frequent water changes because their tanks look like little bogs just filled with moss and duck weed. its also in a really bad area. tons of homeless people and NOT near Ghirardeli Square at all. last time i went there there was a giant pile of human poop in the middle of the street. if you want to visit sf go to AFA. what are you actually looking to buy?
