I'm blessed to have 3 very cool and very different stores in my area. I've listed them in the order that I discovered them since starting saltwater in January.
The first has both fresh and saltwater stock. It always has a good selection of fish, and cool inverts. There is aptaisa all through their tanks though and recently, bubble algae all over the frag tanks. The store is a bit dirty, but cool. The various staff are helpful and it's usually busy. I've bought 3 coral, a fish (and lots of freshwater fish and plants), and a nem there. I don't think that I'll be buying anymore coral there - there was even bubble algae growing on the underside of a nem that I looked at a couple of weeks ago.
The second store is immaculate, has a lot of high end coral and equipment, but less of a fish selection. There are no bad critters anywhere in the tanks. It's not been busy when I've been there and I've always been able to speak with the owner. I've bought 3 coral, 2 fish, a nem, and some equipment there.
The third store, I just visited last week. It's a bit outrageous - a giant 900 gallon display tank is in the front room. The sale tanks are just loaded with stuff, mostly sps, but some other cool stuff too. Some of their corals have been in the sale tanks for many years and some are not for sale. Very cool staff. I bought a coral there when I visited.
I've acquired most of my stock from local reefers though - 15 corals and 4 fish.
