It was ok, barely 3 stars, maybe good for the Koreans, though subpar for foreign tourists.

Performance in the ocean arena was average, more for the kids and teenagers maybe, it was a success with the visiting locals though.

The aquarium itself has a decent variety of tanks. Definitely nowhere close to the big aquariums in Asia as some reviews try to allude to.

Not all tanks were very well kept and there was misinformation on a few signs on where some of the fish are from, such as some South American fish (Oscar and others) informed as being from the Mekong River in Asia and some North American fish (alligator gar and sturgeon) as being from South American Region.

South American freshwater tank as much as had wrong information was cool, plenty of huge arapaimas. Though tank was very small for the size and quantity of fish.

A few cool little invertebrate tanks was the highlight for me, though they could do better with better research to give correct information to visitors and cleaner and bigger tanks. Some tanks are extremely small for very large species.

Small Freshwater fish were very disappointing, most fish easily obtainable from aquarium shops. I've never thought I'd see goldfish having exhibit In a public aquarium (they had 3 exhibits for types of goldfish and carp).

Had to wait quite a bit to get our tickets from the internet validated at entrance. As signs pointed to wait on specific booth with no staff, other booths had staff which didn't seem to care that there were visitors waiting.

Food amenities were very good for a large public aquarium. Price for the tickets and food was also cheap.

It's definitely not a bad aquarium, and could do much better with a bit more effort, a more modern approach to the ambience and if it did a few things better. There's good infrastructure and great location already.
