Description: This may be one aquarium you want to skip with the kiddos. Full of terrifying creatures from the sea The Haunted Aquarium's newest exhibit is a history of the Underwater and Undead. We don't even want to know what that means but we can guess from the exterior of this expertly detailed aquarium. Skulls are in the landscaping while the doorway is the mouth of a serpent for an eerie entrance. Set aglow like the depths of the sea bottom this aquarium is not for the weak of heart.
