In the video, we see a person's hand reaching into an aquarium filled with water and coral. The person is touching and moving the coral around, possibly to clean it or rearrange it. The coral is a mix of different colors, including pink, purple, and white. The water in the aquarium is clear, and we can see the light reflecting off the surface. The person's hand is visible, and they seem to be wearing a ring on their finger. The coral appears to be healthy and well-maintained.
