close-up of a marine aquarium

close-up of a marine aquarium. The focus is on several anemones, which have long, slender tentacles that are a pale purple color. The anemones are attached to a sandy substrate at the bottom of the tank. In the background, there is a rocky structure with a dark opening, possibly a cave. The water is clear and lit with a blue tint, which enhances the colors of the marine life. The scene is still with a slight movement of the anemone tentacles from the water current.
