they can. but it is VERY rare. usually you would see a bubble nest.
the male betta fish makes the nest.
There is no need to remove them. The fish is building his nest and is ready to breed he will only make more.
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
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.
Just leave it. If you really want to remove it you can, but it's just a sign of a healthy betta.
Betta fish reproduce through a process known as spawning, where the male builds a bubble nest and entices the female to lay eggs. The female releases eggs, which the male fertilizes and then collects in the nest. After fertilization, the male cares for the eggs until they hatch, providing protection and maintaining the nest. This reproductive strategy allows bettas to successfully raise their young without extensive parental involvement from the female after spawning.
the Betta or Siamese fighting fish
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.

The male will make a bubble nest when the female is about to lay her eggs.
Place a female in close proximity where he can see her.
