In the video, there is a large shrimp and a small lobster in an aquarium. The shrimp is orange and has long antennae, while the lobster is blue and has a smaller body. They are both swimming around in the tank, which is filled with small rocks and pebbles. The shrimp is moving its antennae around, while the lobster is crawling on the rocks. The aquarium appears to be well-lit, and the water is clear.
