The young guppies can be combined when they are about one month old. At the beginning of tank closing, we should observe the state of young fish more. If they are not suitable for living with big fish, they should be maintained separately immediately. If the young guppies are fed with meat feed, their growth rate will be accelerated and their body shape will grow rapidly. In this case, the cylinder can be closed in about half a month. After the cylinder is closed, normal maintenance is ok. First, does the peacock fish cub need to be kept in isolation? The peacock fish cub needs to be kept in isolation just after it is born. Because the female fish consume a lot of physical strength after giving birth, their hunger is obvious. At this point, they may eat small fish. Therefore, when the guppy gives birth to its young, it is necessary to prepare a sterilized fish tank in advance and prepare to put the newly born guppy young.

Second, how old can the guppy be combined? Generally, after growing for one month, the body shape of guppy cubs will change significantly and become bigger. The cylinder can be closed at this time. If the guppies are fed with very nutritious feed, they will grow quickly, which usually takes more than half a month to close the tank. If the growth of guppy cubs is not good and their physique is weak, they can be kept for a long time and then kept in the tank for maintenance. If the young fish keep hitting the fish tank or swimming after the tank is closed, it means that they are not used to it, so they need to be fished out and maintained separately, and then re-closed when they grow up.

Iii. Precautions for guppy after tank closing 1, temperature: guppy cubs are sensitive to water temperature and should be kept at about 25 degrees. Oxygen should be given immediately if the temperature exceeds 27 degrees. Especially in hot summer, it is necessary to observe the state of guppies more. If there is a situation of rising head, it means that hypoxia has begun. At this time, the oxygen pump should be turned on immediately to avoid suffocation.

2, change water: guppy cubs have higher requirements for water quality, generally need to change water three times a week, that is, they need to change water once every other day.
