1. How old does the map fish start to develop color Map fish is a relatively large type of tropical fish. Under normal circumstances, the longest length of this fish can reach about 30 cm by artificial feeding, so the length of adult map fish can reach 35 cm. This kind of fish has a fast metabolic rate, rapid growth and development, and its life span is relatively long, which can live to about 10 years old. This fish begins to develop color when it is about 20 cm long. Map fish belongs to oviparous fish, which enters sexual maturity about 18 months after birth, and its breeding period is about July-October, and it can lay eggs many times a year.
2. What to eat helps map fish to develop colorShrimp and shrimp are one of the foods to promote map fish to enhance color better. Some synthetic feed can also achieve the purpose of adding color to map fish, such as treasure red, ten-day red and so on. Feeding shrimp or red worms will promote the hair color of this fish, mainly because these foods contain astaxanthin.
Astaxanthin, also known as astaxanthin, is found mainly in the flowers, fruits and leaves of crustaceans, some salmon fishes and green plants. Astaxanthin is a kind of pigment, which can make fish, shrimp and crab appear red. Therefore, you can also feed some small fish, shrimp, loach, bread worms, etc., but these foods are easy to carry some germs and parasites, so they should be sterilized and then fed to map fish.
