**UPDATE: it has been about a month since we have been to the aquarium and I am pleased to report they no longer have jellyfish they couldn't keep alive in the first cylindrical tank. It is now sharks. Although it seems small for the sharks, it was a much needed improvement. I have added those photos below.
We have an annual pass and visit about once a week. They are continually adding fun things like the giant light bright and the color and scan area. They do however have a very small, very sad, enclosure for the sloth and birds. They receive NO natural light and I have seen the sloth hanging from the net looking miserable. Also, every time we go there seems to be jelly fish floating at the bottom of the tank. They are always replacing the dead ones and the tank always looks different every time we go. They should focus on more kids activities and less on the animals if they don't know how to properly care for them.
The complex itself has a TON of fun things for kids to do and plenty of space to run around. Check out the Four Peaks store with the mine experience and the arcade.
We continue to go because it's overall a fun experience. The low review is based on the treatment of some of the animals. We hope they continue to add more kid activities in the aquarium.
