You can add to a males nest or even encourage one to build it bigger by taking some bubbles from another males nest using a spoon and putting it into the first males tank.
they can. but it is VERY rare. usually you would see a bubble nest.
Your betta will only make a bubble nest if there is a female present in the tank typically by placing her in a breeder tank available at most local fish stores. Also I would suggest to have some floating plants, and some sort of plants so that the bubble nest can be anchored.
The male Betta builds a bubble nest at the surface of the water. The ova(eggs) are fertilised under the nest then collected by the male in his mouth as they sink. He then places them in the nest where he tends them.
It can not be mistaken for anything else. It is a tiny bubble at the surface of the water but it will not be a single bubble for more than a minute or two. The male Betta builds his nest quite rapidly.
Yes and No. The betta will make a bubble nest, but it is helpful to the betta to have the bottom half a styrofoam cup in the tank for the betta to build it on, it would most likely build one anyway if there was a place to build one though. Good luck!
As soon as the male has put all the eggs in the bubble nest.

Actually, with bettas it's the male that cared for the bubble nest rather than the female. You should leave the male with the nest and separate the female.
He'll get over it and make another eventually.
Place a female in close proximity where he can see her.
The male will make a bubble nest when the female is about to lay her eggs.
Male Betta's do not have babies. The female lays the eggs, the male fertilizes them and then takes care of them in a "bubble nest" that he builds until they hatch.
