Water temp is the key, bettas are a bubble nest builder, that does not mean they will constantly build nests, its important if the fish is alone "to build a nest" that there are no sudden water temp changes, and the fish is living in some what of clean water and is being fed, the short answer to your question is no I would not be worried. the fish is no different than anything else it moves on an then goes back to what it species has done forever. One other thing that has come to my attention or thought, the betta that you have is a mature male betta.
No. Bettas sleep a lot. It's good for them
Female Betta fish do not make bubble nests.
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.
It probly is a female
it looks like they have a big bubble in their side
If you would like to know what gender your betta is, look for the egg spot. (for females) It should be a small white cloud between the head and body. If your betta has one, it's a female. If your betta doesn't have one, it's a male.
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!
check the PH in the water,
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.
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.
Maybe your female betta is a lesbian lol
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.
