I have looked around past couple of years and I haven't found any. Mostly "guppy mills." However, there's been some notables. I'm out in Orange County, but I do like "The Reef" on State College blvd (which I think is in Fullerton or Anaheim) but don't be fooled by the name. They have mostly fresh water fish. Also for those looking for the rare small fish, I have found an interesting little hole-in-the-wall that specializes in small fish and nano tanks. It's on Hawthorne BLVD just as it enters Lawndale. The name of that one is "The Lotus". I have seen smaller fish in there that I never new existed. Most all of the others I've not been impressed with--even those that are highly acclaimed by other fish people. They've told me that the best around is "such and such" but when i get there, I'm utterly disappointed because it's just another "guppy mill". Of course, what is good and what is not, is just an opinion and entirely based on personal preferences.
