I'll go first with the ones I know of in Miami, FL
Name - Gables Aquarium
Location - 8295 South Dixie Highway
Store Size - Small Store, but has everything you need
Customer Service - They have great customer service, and the employees have all been working there for a very long time. Unlike other LFSs, I think these guys know more then the others. Best in Miami IMHO.
Pricing - Prices are pretty average. They definately don't have any corals or fish with outrageous prices. They are very reasonable, and you definately find some great deals there from time to time.
Selection - They have alot of saltwater stuff, and a small fresh section. They also carry a decent selection of foods/supps
Services - They offer damn good maintenance programs, and also offer custom tanks/sumps/etc.. Great Glass work.
Great store to for corals and fish, and great for building custom glass, and more advanced stuff.
Name - Exotic Aquariums
Location - 7399 SW 40th St
Store Size - Larger Store, lots of space
Customer Service - Custom Service is great, they always ask if you need help. Unforunately they are not very experienced and sometimes offer bogus advice. I almost cried when one of them instructed me to build a plenum to filter my 5.5 gallon tank. HAHAHAHA!!
Pricing - Their Prices aren't bad for fish. But they're coral prices are absurd most of the time. $30 for tiny frags of Xenia?? Get real. Almost anything that's a decent sized frag will be expensive. Eg - 6 polyps of plain old red blasto is like $150 there.
Selection - Lots of corals, lots of fish, lots of inverts, TONS of drygoods, and a big freshwater section as well. Every Tank size you can think of is there.
Services - Not really too sure about that.
Misc - They also have a pond section, bettas, and 2 nice display tanks, one a stony the other a softie tank.
Decent Store to buy fish
Name - Amazing Aquariums
Location - 8343 Sw 40th St
Store Size - Pretty Big Store
Customer Service - You can tell this is a family run business because of how friendly they all are. They dont really have awesome advice if you were to ask, but they know enough to help beginners.
Pricing - Best Prices I've seen in Miami, large frags at great prices. I picked up a Blasto there with 5 huge polyps for $40, and an outrageous Purple Lobo for $45. Awesome coral prices.
Selection - Lots of corals, lots of fish, decent inverts, decent fresh, lots of drygoods, not too many tanks though.
Services = No Idea
Misc - They have a decent 1000 Gallon Tank, but everytime I go in there it looks worse. I wish they kept it up, last I saw it, it had a bad cyano outbreak. And its not very week stocked.
Great store to buy frags!!! But that's about it!
Name - Strictly Aquariums
Location - 83rd and Bird Road - Right next to Amazing
Store Size - Small Store
Customer Service - They've never been to nice to me there, or overly helpful in any way. Pretty Crappy IMO
Pricing - Prices are pretty average, maybe a tad on the high side.
Selection - Small freshwater section, unimpressive saltwater section. All their live rocks come covered in Massive aiptasia. I bought one coral from there and it came covered in flatworms, thank god I dipped.
Services - No Clue
Misc - Nothing
Not a bad store at all, but it doesn't really have any redeeming qualities. Staff is whatever, selection is ok, etc etc.. They need something.
