You were a mermaid (or merman) whi had recently been captured. About a week ago, from fishermen. You were put in an aquarium, and were a regular for the people. As for the security..they were cruel

Today was no different. You swam while everyone watched in awe, a big crowd in front of the tank. After a while you hid behind a rock, and a man in a leather jacket came walking in. It seemed like he had heard about you. The security Gave a stern look, as if saying 'quit hiding and get out there'
