How long should I keep male and female bettas separated for breeding?

You can keep a male and a female betta together for a short time for breeding purposesm however if you intend to keep them together for longer they will eventually start to fight. So it is not ga good idea to put them in the same space.

You will need to use a solid or opaque divider to obstruct their view of one another. If they can see each other, it can stress them out. As the male matures, he will want to breed with the female and she will spend time swimming as far from the divider as possible to move away from him.

Beta fish lay eggs and she would need a male to then fertilize those eggs after she lays them. Breeding betas can be very work intensive. Here is a link with great information: fishkeepingworld.com/breeding-betta-fish/ As the babies get bigger, they can graduate to larger food. The babies will mature and need to be separated around 3 months of age. The females can stay together but all the males will need to be separated. Breeding betas requires a lot of tanks/space. I recommend to connect with a local aquarium store and find out if anyone has first hand knowledge. I hope this helps and please feel free to post any additional questions.

Bettas, both male and female, are considered "full grown" at about 7 months of age. There may be some growth until a year of age with most specimens measuring 2-2.5 inches in length. Freddie looks to be in fine form in the images provided. Be sure to maintain water quality and temperature. Bettas do best between 78F and 80F. For water changes, use only aged or conditioned water that is temperature matched to prevent stress or shock.

A male Betta can be kept in a 10 gallon tank with 5-6 neon tetras. You will need to monitor for any aggression initially as well as for any fin nipping. Male Bettas are easy to distinguish from females by their brighter colors and larger fins.

She shouldn't be bred until she is at least 10-12 months of age. If the male is younger than that, then she certainly is not ready to mate and should not be forced. This will result in stress and possibly the loss of eggs or chicks. Separate them to give her a break from his advances until she is old enough to mate.

She appears to have eggs given her girth. There are also some vertical bars on her side that indicate she may be ready to spawn. If possible, check underneath for a pronounced white dot. This is further proof that she is ready to spawn.
