you can put two girl bettas in one tank but not the males
No the two male bettas will kill each other if they are put in the same tank.
no they are too territorial
If you wish to have two live Bettas you will have to keep them apart. Otherwise they will fight and one will kill the other.
They Can't Be. As If You Put Two Bettas In A Tank No Matter The Sex. They Will Tear Each other Apart
If you mean 2 other female bettas, probably not. Females generally are non aggressive and do fine with other females.
I have heard of people that have had two bettas in the same tank for years and they haven't faught. But make sure that the tank is over 20 gallons so they can have more room to get away from each other. But I recommend NOT to have two bettas in one tank.
Bettas are bubble nest builders so if there are eggs they will be in a mass of bubbles at the surface of the tank. A male Betta will not tolerate another Betta in its tank with him so if you have two Bettas in a tank they are either too young to fight or they are two females that will not normally fight. To clean the tank you should put the fish into a large container containing water of the same temperature as that of the Bettas tank. You clean the tank properly and set it up (not forgetting to add some chlorine remover) and equalise the temperature before returning the fish.
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.
I am assuming you mean Bettas. A male Betta needs to be kept away from all other Bettas. They can not be kept together. The male would kill at least one of the females. Then he would either breed with the living female and then kill her if she is not removed or he will try to spawn her and if she is not ready he will kill her anyway. This is how the Bettas evolved. Although they will mix with most other species OK male Bettas will not tolerate another Betta in their tank.
No. The tank is not large enough to house two female bettas. The basic fish keeping rule is "1 inch of fish needs 1 Gallon of water". A female Betta grows to around 1.5 inches so you would need at least a 3 gallon tank to house the 2 Bettas properly.
With or without a dominant fish in the tank two female bettas shouldn't fight. It's only the male of the species that fights.
This is a BIG NO NO!! Bettas need at least 2.5 gallons of water to themselves, and if you put a male and a female together, it will most likely result with you have two dead bettas. Keep your boy and girl in separate 2.5 gallon heated tanks.
