This place is all right, but absolutely not worth paying full price for. Wait for a coupon or a deal or something, and then come down and take a look at the fishies.
I couldn't help but compare this aquarium to the one at Wildlife World Zoo in Litchfield Park. I absolutely prefer that aquarium over this one. Pay about $10 more than the admission price to the AZ Sea Life Aquarium and you get admission to both the Wildlife World Zoo and their aquarium, a much more relaxed and entertaining place.
Anyway, back to this aquarium. It is crowded (we had the misfortune of going when 3 charter school groups decided to go). It is hot, when everyone is packed in like sardines. Everything is at kid-level so there's a lot of stooping. The plastic/glass is already covered in fingerprints. No adults watch their kids and for some reason people bring strollers in, which do not have enough room to maneuver.
The animals themselves are cool. There are rays, my absolute favorite, and sharks, and jellyfish. If you get a few moments to yourself without some ten year old shoving his way past you or a stroller taking out your ankle, you can enjoy watching them enjoy themselves.
