One of the first things you see when you enter this place is a giant shark tank. Pretty cool. But then I start to feel sorry for it and the novelty wears off. Poor shark.....
What I really come here for is to check out the plethora of tanks in the back. Tons and tons of smaller fish, crabs, shrimps, etc. If you see any fish you want, you have to grab a clip board and write your "order" down. Then you have to get the attention of a sales associate or wait for one to be finished with another customer. My tip is to follow the sales associate to each tank you're getting your fish from. If you're not there, they might try to pawn off the not-so-healthy looking fish on you.
They also have a selection of lizards here for sale (anoles, bearded dragons, chameleons), and I believe they sell crickets too.
My boyfriend is the real fish expert and loves Big Al's. He says this is the best place for all things fish/aquarium related including: accessories like gravel, fish pumps, lights, aquatic plants, tanks, filters, and of course, fish!
