In the video, two men are seen sitting in front of a fish tank. One of the men is holding a small electronic device, which he is using to control the fish in the tank. The fish are swimming around and responding to the device's signals. The men are focused on the device and the fish, and they seem to be discussing the process. The fish tank is well-lit, and the water is clear, allowing for a good view of the fish. The electronic device appears to be a small black box with wires attached to it. The men are wearing casual clothing, and the setting seems to be a home or office environment.
