  • Aquarium still under renovation i guess. But my daughter still loves going there. It would be nice if they add more sea creatures!!!
  • Loved all the large specimens with all the special information on all of them. I did not realize some sharks can sit on the bottom and still breath. Learned about the upside down jelly fish. Saw the biggest eels I have ever seen before.
