Color-bellied fish and zebra fish (red horse and yellow zebra). Color-bellied fish ~ ~, also known as light fish, is an artificial laser variety of black-bellied fish, with a body length of about 6 cm. The first half of the fish is very wide, the second half suddenly narrows, and the body is translucent. The male fish is small in color, the female fish is large in color, and the abdomen is obviously enlarged during the breeding period. Colored-bellied fish are gentle, love to swim in lower waters, and are afraid of being scared. If the environment is noisy for a long time, the body will become pale. When the water temperature is lower than 20 degrees for a long time, the body color will fade and disappear.

Zebrafish ~ ~ ~ is gentle, small and exquisite, and swims around the aquarium almost all day. It is easy to raise and can be mixed with other kinds of fish. The feeding water temperature is 20 ~ 23℃, and it can still survive at water temperature 1 1 ~ 15℃, and the requirements for water quality are not high. During daily feeding, put some pebbles at the bottom of the aquarium to make the water clear.
