Be cautions about buying live goods from 6th Ave, the cheapest prices, but not always the best. I've had several fish die from them. Personally I spend alittle more and get better stock.
Aquatic Central is good, prices are getting high.
Hung Ming good too, also a bit high.
If your open to a drive the Vallejo Aquarium has good stock and prices, not as many odd balls but it's a quality store.
Also Aquarium Concepts has great quality fish, no oddballs and deals with Salt more but good stock, and market value fish.
Kings Aquarium in San Jose may be one of the best Bay Area's stores Fresh wise, good prices, stock and odd ball selections
