Neon Tropical Fish Close-Up in a Dark Aquarium

Ultra-detailed close-up macro shot of a tropical fish swimming in a dark aquarium. The fish features iridescent turquoise and cobalt scales, electric yellow fins, and a vivid orange patch near the head. The water around it is pitch-black with tiny floating particles and a few bubbles. A cool, overhead LED beam provides rim lighting that makes the scales shimmer, while subtle caustics ripple across the body. Shallow depth of field with the eye and scales in razor-sharp focus; background rendered as deep blue-black bokeh. Include realistic aquarium glass reflections near the edges and a cinematic, moody atmosphere. High-resolution, 8K quality with crisp textures on fins and scales, color graded to emphasize neon hues.
