Male betta fish may construct bubble nests without the presence of a female. They may make several such nests over the course of a year, depending upon the male. In the wild, the male leads the female under the nest once it was complete. After a successful courtship dance, the female releases the eggs into the water. The male gathers the eggs, fertilizes them and stores them in the safety of the bubble nest.
Betta fish, which originally hail from the stagnant pools of Southeast Asia, are frequently kept as pets in Europe, Asia and the United States. However, the vast majority of the fish that reach pet stores are males, as breeders in Southeast Asia hold back the females so that they can produce eggs. The males also have the bold colors that make the fish such popular pets.
Betta fish can survive dry periods of time by burrowing down into the wet mud at the bottom of their habitats.Learn more about Aquatic Pets
