Construction
Bubble nests are built even when not in presence of female or fry (though often a female swimming past will trigger the frantic construction of the nest). Males will build bubble nests of various sizes and thicknesses, depending on the male's territory and personality. Some males build constantly, some occasionally, some when introduced to a female and some do not even begin until after spawning. Some nests will be large, some small, some thick.
Various things have been shown to stimulate bubble nest construction, such as quick temperature changes, barometric changes, fluctuations in rainfall, materials in the tank, and presence of other males or females.
The nests are built by the male (sometimes females) and their size, position and shape depends on the species. They are often built near an object that breaks the surface of the water, which forms a base for the nest.
Bubble nests created by male betta/Siamese Fighting Fish (Betta splendens) are made from air bubbles coated with saliva to increase durability. This makes a louder noise than regular breathing and is often frantic behavior.

Famous quotes containing the word construction:
“No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.”
—T.S. (Thomas Stearns)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
“No construction stiff working overtime takes more stress and straining than we did just to stay high.”
—Gus Van Sant, U.S. screenwriter and director, and Dan Yost. Bob Hughes (Matt Dillon)
