There shouldn't be any problems with that. If you are trying to avoid fry, I wouldn't worry about mixing genders - the fry usually get eaten within 2-3 days of hatching if you leave them in with the parents.
Yes. Don't keep males and females together.
Male koalas can be kept together as long as they are not within a colony of females. If they do not have any females or territory to fight over, they can live peacably together. Native wildlife sanctuaries often keep several males separate from the females quite successfully.
They should live 2 or more. But male mice can't live together always. If you see your male mice fight or beep you should split them. Also i don't recommend to have more then 10 females together.
yes they will because the male will probably have babies with all three
whichever your most comfortable having - But two males are more likely to fight than two females, unless they have been brought up together! :D
Yes. My chain of command is male (my subordinate), female (me), male, female, male, male.
The male and female sperm whales live apart, the females group together with other females and their to make a pod. A pod is about 30 whales. But killer whales stay together with their young and stay together their whole live.
During the mating season, male giraffes slam their necks together in fighting bouts to determine which male is stronger and can therefore mate with females.
It is usually not advised to keep two male rabbits together, especially if there are females nearby. However, if the pair are acquired together as youngsters, like littermates, and neutered before they reach sexual maturity, the chances for successful cohabitation greatly increases.
Um... At least a month and a half. If the male is showing signs of aggression toward the babies you should keep the male in a separate cage.
If you try to keep a male and female (or females) in the same tank permanently, the outcome is always going to be seriously injured or dead females. You cannot keep males with females. Under very carefully controlled circumstances during breeding the male will not kill the female (he will usually nip at her, but not seriously harm her.) But male and female in same tank = dead female.
If two male Betta (Siamese fighting fish) meet, no matter the volume of the tank, they will fight. Some breeders will put opaque sheet partitions in the tank to keep the male fish out of sight from each other. Females will happily keep together in the same tank.
