The tank was huge, it goes 30ft down and is over 80ft wide. But there were 2 very valuable sirens on display. If only the people outside the glass snapping photos and having fun knew what was really going on here. The owner was a mad man who tests on the sirens. Odin (test subject B32- a rare orca male siren), was laying down on the big rock at the top of the tank, the fake sun was very relaxing on his body.
