A large cardinalfish, rendered in a hyperrealistic anatomical style with meticulous detail, is adorned in an exaggerated, vibrant costume of meticulously draped navy blue and coral fabric. The fish's scales exhibit a subtle iridescent shimmer, and its fins are intricately patterned to resemble flowing garments. Focus on the precise textures of the fabric folds against the fish's scaled skin, the sharp definition of individual scales, and the bioluminescent spots subtly glowing along its underbelly. Additionally, depict the exaggeratedly elongated pectoral fins reaching beyond the body, and the prominent, realistic depiction of the cardinalfish's large, expressive eyes.
