As for stores, might want to check out ALL ABOUT FISH in Concord (don't know the address, but it's right off of I-680 just a little south of Hwy 4). Don't know about acrylics, but they have a pretty large selection of tanks. Went there during a sale and almost got an AGA, but passed on it (Glad I did, found the same set-up at a greater savings somewhere else).
Lots of fish there too, but I can't comment on the quality of their livestock, although it all looked fairly healthy last time I was there.
