This image depicts a vibrant marine reef aquarium, illuminated primarily by blue actinic light, creating a deep blue environmental hue. The scene showcases a diverse collection of tropical fish and stony corals within a structured aquatic environment. In the upper-center, a blue tang (Paracanthurus hepatus) is prominently visible, characterized by its electric blue body and black markings. Below and to the left of the blue tang, a black and white clownfish (Amphiprion ocellaris or percula) is present among purple branching corals. In the mid-left, a black tang with a distinct yellow caudal fin (Zebrasoma xanthurum) is positioned near a large, highly textured, bright green coral colony. To the right, in the mid-right, a Naso tang (Naso lituratus), identifiable by its dark body, white and orange facial markings, and yellow caudal fin, is partially visible. A light blue-grey tang is partially obscured behind the Naso tang in the lower-right. A small, reddish-brown fish rests on the light sandy substrate in the lower-center. The aquarium features extensive live rock formations and numerous branching stony corals (Acropora species) in various shades of blue, green, and light purple, creating a complex habitat with multiple crevices and an arch-like structure in the mid-background. The substrate is a light-colored sand. The specific location within Mexico City, Mexico, cannot be determined from the visual information presented in this image, as it solely captures an internal view of an aquarium.
