Depends on the male if it usually goes in the nest then yes
it is the male and female that make the nest. if there is only a male then it may be harder to build a bigger nest.

Parakeets lay fertile eggs when they are with the opposite gender (i.e male with female) and they have a warm, comfortable place to lay it such as a nest box.

It can take years,depending on their age.I'd fix a nest box to put in their cage.Sometimes that will help encourage them.Just be patient.

During the courtship process, the male betta will often follow the female around the tank, flashing his fins as a show of display. It is not uncommon for the male betta to be mildly aggressive to the female. The male will also build a "bubble nest", which is essentially a mass of bubbles that float at the top of the water. When the female has been courted and is ready to lay eggs, she will lay her eggs in or near this nest. The male will then spend most of his time watching the nest and replacing any eggs that fall out. The female at this point has no role in the care for the fry.
