PM'd you a good resource.
Reef Hot Spot is your best bet. Large warehouse with varied selection of fish and wild/maricultured coral. Max, the owner, is a good guy and prices are competitive.
Santa Monica Aquarium looked like it had potential the one time I visited.
Medusa LA is expensive and the livestock is hit or miss.
Beyond that, you'll have to travel down to the South Bay/OC or to the Valley for better LFS.
