To accommodate the developing eggs, the mother’s body expands, becoming deeper and broader. A few days before delivery, she develops a bulge below the gills, her outline becoming fairly square in this region, while the gravid spot has enlarged its area.
However, the gestation period could vary from one species to another. Even so, the most common time period is about 4 weeks. This is the time that has to pass from the moment of egg fertilization, to the moment when the birth is taking place.
What do I do if my fish is pregnant?
Ideally, pregnant females should be placed on their own in a separate aquarium with lots of feathery plants where they can give birth in a stress-free environment. Then again, once she releases the fry she is returned to the main tank and the fry can be grown on separately.
Some egg-laying fish create nesting areas to keep their eggs safe. These may look like small pits or gravel mounds, but they are not always visible. Some gouramis can create elaborate nests made from a mass of bubbles, usually created by the male along the water surface.
