It makes me sad that this Big Al's doesn't have better ratings. When I was setting up my aquarium I came here almost once a week and had good experiences each time. I loved waiting for their weekly flyer to be released to see if anything caught my eye. The quantities on sale are limited though, so try and come earlier in the week if they're having a good deal.
This store is *huge* with small pets, reptiles, and aquarium supplies upstairs as well as an enormous fish selection downstairs. IMO they have a good system for fish shopping. You grab a clipboard, wander around and write down which fish you want / the tank # / quantity, and then go wait in line by the counter and they'll grab the fish for you. The lineup is first come first served and gets super busy during peak hours.
A lot of the staff here are pretty young but I respect that and it's great to see how passionate they are about aquariums and fish! I've picked up lots of pointers from them along the way.
My only complaint is that the plants I brought home unfortunately infested my tank with snails.
Pro trip: Come Tuesday at 7:00 to watch them feed the shark! Actually, come at 6:50 because they start at 7 sharp and there are lots of families.
