first make sure they are FEMALE. then put them in the same tank AFTER THE TANK HAD BEEN CLEANED. Watch them closely for a couple days and if they seem to be alright then just keep an eye on them. If they fight then you MUST SEPARATE THEM.
About two weeks before you intend to spawn the bettas, you should start conditioning them. Feed them on as much high protein food as possible. One or two feeds of a tiny amount of raw meat (liver is best) or cooked fish or shellfish will do them good. Feed live food if at all possible. Keep this up for two weeks. The female should start to look plump (full of eggs). The best thing to do is to set up a breeding tank. I use a five gallon plastic tub. Use a heater set to around 24 C. Add some plastic plants for shelter. I provide a styrofoam cup cut in half for him to build a bubblenest under. Half fill the tank and add the male. Let him settle in for a few days. Add a large glass jar to the tank and fill it with tank water. Put the female in this jar and watch them closely. Both fish should start to appear somewhat excited and the male will blow a bubblenest if he has not done so already. If he has, he will make it larger and thicker, alternating nest building with displaying to the female. If the female is interested, she will spend most of the time watching him and by the second or third day in the tank will develop broad vertical bars on her body. When the nest is completed, the female full of eggs and the fish are interested in each other, release the female. At this point they must be watched closely. You should check on them every hour or so because things could get nasty. DO NOT release the female if she is acting uninterested. In the wild if a female encountered a male's display and did not like what she saw or was not ready to breed, she could choose to leave. When in a tank, she does not have this option. Staying indicates interest in mating, so if she stays close to him but does not accept his advances the confused male could decide she is a threat and attack or even kill him. If all goes well, they will spawn within a day or so. Some flaring or fighting is to be expected, but if either fish acts distressed or is very badly hurt, put the female back in the jar and wait to see what happens. Once they have finished spawning you should remove the female as soon as possible. Otherwise the male will think she still contains eggs - again because in the wild, she would leave. When she rejects his attempts to continue spawning he could kill her. He may also see her as a threat to the eggs and attempt to drive her away.
an white spot will appear on her stomach
Ur betta is ready to breed
No, Betta fish are aggressive toward any other fish they see. They cannot mate.
There is no need to remove them. The fish is building his nest and is ready to breed he will only make more.
The simple answer is no.
Yes! Betta fish males can make bubble nests whether or not a female betta is present! Male bettas make nests when their home are in proper conditions and they are ready to breed.
its a bubblenest .. its where the female bettafish keeps her eggs
If you can get a female of the same type as the male you have, that is best, but any female Betta will spawn with any male Betta provided they have the correct conditions and are both ready to breed.
Yes, Betta fish can jump. You can teach them to jump by placing a small amount of food on your finger and when your betta fish is ready, it will jump and take the food off your finger! :)
He might just not be ready yet. Males either make bubble nests out of happiness, or if they are breeding. If you want him to breed, he might just not be ready yet.
Yes all bettas can mate with other bettas. " regular betta fish" there are different types and they can all breed together.
This is not a Betta question so it belongs elsewhere.
by same i think you mean color, which in case is no, they can be different colors and breed.
