In order to describe the beautiful colors of tropical fish, people have written countless articles. One article recorded the color of grouper and wrote: "The beautiful magenta background color turns yellow when it reaches the abdomen, and there are many bright colors scattered on the sides. cyan spots”. The golden eye bream is described as: "It has the same bright background color, plus the luster of various white gemstones, especially the reflected brilliance of cyan and light purple." "The horsetail has irregular and dark black patterns on the tulip background. The pectoral and caudal fins are beautiful orange, the other fins are yellow, and the filamentous fins in front of the pectoral fins are beautiful vermilion." The double sawfish is a small coral reef fish. Its body surface has a bright orange background, three broad, blue-gray vertical stripes on its head and body, and black or dark blue edges on each stripe. Most of its fins It's lemon color with a black narrow edge." The boxfish's "bright colors and strange patterns may be more beautiful than any other fish."

Common biological color phenomena include covert color (protective color), warning color, eye spots, mimicry, gender color and other biological color phenomena. These are the products of long-term adaptation of fish to the environment. Survival and reproduction are of great significance.
