Most sunfish have outstanding colors, and the most eye-catching species among the beautiful sunfish is this one called Chang 'e, whose dazzling metallic blue color fish is covered with orange stripes, and the dazzling and beautiful eyes have a pair of ear-like patterns at the back end, which is their obvious sign.
There are about 30 species in total, which belong to fish that spawn many times. The staple food is zooplankton and aquatic insects, but also aquatic plants, small miscellaneous fish and small mollusks.
Distribution range:
Sunfish are native to North America, and are distributed in rivers and lakes from Ontario, southern Quebec, Canada to the Great Lakes system of the United States, and in many southern States of the United States and northern Mexico. Individuals are small, usually 50-100g/tail, and large ones are about 2kg/tail.
From the morphological point of view, the blue gill sunfish is somewhat similar to Nile tilapia, and the most striking appearance feature is that there is a black ear-shaped soft membrane on the rear edge of gill cover, which is a common feature of all sunfish, except that the "eardrum" of different species has different colors and shapes.
