In the video, there are two men standing next to a large tank. One man is wearing a white shirt and a black cap, and he is holding a small crab in his hand. He is talking to the other man, who is wearing a blue shirt and glasses. The man in the white shirt is pointing towards the tank and appears to be explaining something about the crab. The tank is green and has a black umbrella over it. There are also some other tanks and equipment visible in the background.
