The first few days or so they can be kept with the male - which is the one that tends to the nest, not the female - but you must remove them afterwards else the betta can mistake them for food. Since females do not tend the nests they are more likely to eat their fry, however on some rare occasions they will tend to the nest too, but it is not common.
You shouldn't leave the female with the fry, the females kill the fry when they are hatched, that's why the male kills the female after the spawn. It would be best if, when spawning, you keep the female in a breeder or a tall glass in a 5 and more gallon tank. When the male is finished with his bubble nest take the female out so they can do there magic, which really means the male squeezes the eggs from the females body. You have to make sure the female isn't too small or he could kill her. And after that you should but the female in a tank so she can recover. Leave the the male with the fry (baby fish) for 2-4 days after that remove him. When the male fries get older they tend to be aggressive and larger, it would be best if you put the fries in a large cup each so you don't risk one fry killing its sibling. BUT if you single out the males only the female fries should live in peace for a while unless they are as aggressive as a male. I hope i helped you =D (please do not delete)
if female beta fish are put together they would start to fight like the males.
No they cannot, also if you put two Betta fish together, they will fight.
No becaUSE THE MALE BETA FISH WILL FIGHT TO DEATH.
Bettas are dumb as rocks. If you put another betta, any other anabantid like a gourami, or any long-finned fish in with a betta, the betta will fight it because he will think it's another betta. If you put a short-finned fish in with your betta, they'll live together peacefully.
no
you can put a male and female betta together but you must watch them closely, if they fight remove one of them right away! remember to remove them after they have mated
Gold fish require water below 70F and Bettas require water above 75F so they should not be kept together.
You put them together when the female is full of eggs, and when the male builds a bubble nest.
Betta fish are best as a solitary fish and are not compatible with goldfish.
Beta fish don't get along with other fishes, they will attack any fish that they see as a threat. If you buy a female and a male beta DO NOT put them together.
THey will most likely have eggs. Be careful. You might want to put a divider in the tank.
Male bettas will fight other males for no reason. you should never put 2 males together.
