Progressive Marine is a pretty high end store. Lots of quality stuff and pretty neat SPS selection. They are located behind Lowes in Tillman's Corner. Also, I believe they open around 2:00.
Fat Fish in Daphne has a 2500 gallon set up...pretty neat. Last time I was there they had some pretty neat zoas and blastos. Also a few acan lords I believe. Their fish didn't look too hot though.
Just in case you want to stop by a few shops on your way...
You might want to stop by Petsville in Prattville just off of I-65 on hwy 14 across from Dairy Queen (2nd Prattville exit if your traveling southbound).
Aquarium Fantasies is in Montgomery just off the Atlanta Hwy. They have a lot of good stuff too.
God Bless,
