Sturgeon swims upwards, illuminated by light from nearby rock formations.
An upward view of the underside of a sturgeon fish inside a huge aquarium that is swimming towards the lower right. The belly of the sturgeon is white, and the fins along the pectoral and rear are gray with white near the tips. The tail of the fish has large gray scales that have a little bit of white around the border of each one. Beyond the fish, there is a huge rock formation that covers most of the background and casts a dim shadow on everything in front. To the upper right, there is a hole in the rock formation that bright indirect light is pouring through. To the left of the center of the image, another larger hole in the rock formation reveals more well-lit rocky surfaces and a fish that is swimming downward to the bottom.
