We had a little time to kill before a show so we breezed through this aquarium in about 30 minutes. If we had taken our time and used the audio guides provided we could have easily stayed for 2 hours.
This isn't the largest or most extensive collection by any stretch, but it was well laid out, and had a great variety which included: an assortment of rays, sharks, jellyfish, turtles, some odd little duck-faced fish, massive puffer fish.
A relatively inexpensive diversion for the whole family, I would recommend this for the kids.
