Definately the best for acros and clams...with a good selection of Montiporas. I'm not real sure about softies, as I tend to not really look.
Nice people, and they said they would be going online fairly soon.
If you're in Marietta, or anywhere close....make it a point to stop by there.
I live about 7 miles from them. Nice place with lotsa pretty things. A bit high priced and the staff can be a bit arrogant, but a nice shop overall. You should try Petland in Alpharetta, Georgia (another 15 miles or so). Frags the size of colonies for under $25! Can't beat 'em.
