This is a very small aquarium that is affiliated with the University of Hawaii. They do offer free two hour parking, which is more than enough time to throughly check out this place. The aquarium is partially indoors and partially outdoors. In the indoor exhibit you will find seahorses, blue tang fish (Dory), clown fish (Neo), jelly fish, eels, coral, archerfish, clam, unicorn fish, urchin, butterfly fish, angelfish, Hawaiian yellowfin and octopus. I really liked the upside down jelly fish. They were my favorites. I visited the aquarium during the month of October, so it had Halloween decorations and a Halloween them going on.
A large tank holds the Hunter on the Reef exhibit which is home to sharks, jacks and large groupers. There is a photo backdrop that you can take a picture in front of in the aquarium. The aquarium also has a restroom, water fountain and of course a gift shop. The gift shop is small and carries toys, magnets, figurines, hats, stuffed animals, post cards, and stuffed animals.
Outside is where the aquarium has the seal exhibit. Unfortunately the sea lion exhibit was closed during my visit. There is also a stage out there with a decent patch of green space. It looks like it would make a nice outdoor event venue.
I took me about an hour to go through this museum and I was moving slow because I had time to kill. Admission is reasonable so,I did not care that the place was small and it did not take very long to see. I recommend checking this place out, but just do not come in with high expectations. It should probably be on you to-do list while visiting Waikiki, just probably not at the top of it.
