Initially, two whale sharks and one manta ray were captivity in the main tank. However, it received a lot of criticism from animal rights groups because one whale shark and one manta ray died. An official at Aqua Planet Jeju explained that "the cause of death of fish is chronic renal failure and there is no cure", but public opinion moved to release the remaining whale shark, so it was tagged and released.
