newborn small guppy is almost no color. Except for the head, which is a little white, the other parts are transparent. Only when the fish enters the chromogenic stage, its body will gradually appear color. Generally speaking, small fish can not begin to develop color until 1 to 1.5 months after birth. However, under good feeding conditions, they will appear more obvious color in about January. If they are not well kept, they may not begin to develop color until they are 2 months old. It usually takes two months for guppies to get their hair color. When most fish are 3 months old, their body color is basically the same as that of adult fish. A small number of slow-growing fish will stop coloring at 4 months of age.
guppy from birth to adult time required is not fixed, usually related to feeding conditions. And different species of guppies grow at different rates. Generally speaking, the growth and development of peacock fish takes 3 to 6 months. However, most fish are close to adulthood in about four months, while stunted fish need six months to grow up. During their growth, if they are fed high-protein food and keep the environmental conditions suitable, they can speed up the growth rate of small fish. The small guppy that raises well can grow up when 3 months, and can undertake copulatory reproduction.
