Fish of the family Clinidae can change color. By manipulating the chromatophores on the body surface, they blend into the background, making it difficult noticed by predators or prey. The weedfish (Springeratus xanthosoma) is a member of the family Clinidae and inhabits the intertidal zone of northeastern Taiwan. It is often concealed amid colorful seaweed, and has been recorded ranging in color from emerald green to light green, light yellow, and deep red. In September 2021, I encountered a weedfish at an abalone culture pond in the Northeastern Coast for the first time, and was stuck on this fish with sparkling rainbow eyes.
