The aquarium is quite spacious with a good variety of marine life. Some areas are really fun for kids, especially the tunnel and penguin zone. However, a few tanks looked a bit small and crowded. Overall, its an enjoyable experience.

Definitely a fun experience especially if you're coming with kids! Loved watching the sharks and the penguins and the place is beautifully setup

The aquarium was a very standard aquarium. Nothing really interesting stand out. Would recommend to visit around feeding time for the animals as it is more interesting.(around 12-1pm local time). The place is pretty big as well. Overall, was a pleasant experience.

I think it was worth to go once even the price is a bit high. The aquarium is big with many interesting animals and fish. I like the part when people walk inside a big hall and big fish were swimming over their heads. The place is located in a mall which is also convenient to do other activities after our visits.

I enjoyed it a lot. Nice pics there. I could have seen different species of sea life. I recommend if you are visiting around it. It is easy to buy online ticket also and to reach the place.
Indoor exhibits open year-round; visit on weekday mornings to avoid crowds and keep to baby’s routine.
