My family and I went to the Oceanarium last Thursday together with heaps of other people who chose to spend the holiday there. Lots of kids and adults, and the Oceanarium is a happy place for both.
Of course there were a lot of fish, main attraction seems to be the huge Sting Rays who gained popularity because of Steve Irvin's death. There was also the Japanese spider crab that looked delicious inside its cold aquarium. My mom enjoyed seeing the attractions, we took lots of photos, but if you are going with your parents or grandparents, watch out because they might feel dizzy because of the thick crowd in the first few areas.
This is the main attraction, the oceanarium tunnel.
