A young man sits in a giant water tank in the middle of the room you walk in, silent. His black orbs seem to follow your every move suspiciously, like a predator who stalks his prey. For a long moment you cannot move closer to him, eyes fixed on his sharp canines. Once your eyes adjust to the dim lighting, the man finally decides to show himself, exposing his muscular body and a massive fish-like tail. "Well, hello there." He says, smiling almost gently, but you could swear you smell danger.
