Yes, it is recommended to separate a female guppy after she has given birth to 2 guppies.
Here are a few reasons why:
* To protect the fry: Guppy fry are very small and vulnerable, and they can easily be eaten by adult guppies, including their own mother. Separating the female from the fry will help to ensure that the fry have a chance to grow and survive.
* To prevent overcrowding: Guppies are prolific breeders, and if you don't separate the female from the fry, your aquarium can quickly become overcrowded. This can lead to competition for food and space, which can stress the fish and make them more susceptible to disease.
* To give the female a break: Giving the female a break from breeding will allow her to rest and recover her strength. This will help her to be healthier and more productive in the future.
How long should you keep the female with the fry?
The length of time that you should keep the female with the fry will depend on the size of the fry and your personal preference. Some people like to keep the female with the fry for a few days, while others prefer to keep them together for a few weeks.
If you are unsure of how long to keep the female with the fry, it is best to err on the side of caution and keep them together for a longer period of time. This will give the fry a better chance of survival.
