Sea Life Coex Aquarium is inside Coex in Gangnam-gu, Seoul, where visitors can see fish, an undersea tunnel and mermaid shows. The space is not large, but it is divided into small themed areas where the growth stages of fish and jellyfish can be observed. Mermaid shows run every two hours, with the last show at 16:30, and there is also a stamp tour featuring Zanmang Loopy. The walkways are narrow, so when it is crowded, one person stopping blocks the flow of movement.
