Pregnant Guppy Fish Care
Temperature and light are important. The optimum temperature for fastest development of the brood inside of a female is between 77 F and 80 F and development will take approximately 4 weeks in the average live-bearer.
At 68 F, the interval lengthens to some 35 days or more. The female has a normal-shaped anal fin. Slightly forward of this, inside her body appears a dark area which is known as the gravid spot.
Each egg contains an embryo and is well furnished with nutritive elements, provided by the mother's system, on which the developing embryo feeds during its development. However, recent studies show that there is a symbiotic relationship between the mother and the developing fry with an exchange of fluids, the total extent if which is still under investigation.
As the eggs incubate, the eyes of the fry are sometimes visible through the thin walls of the gravid spot. 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. When the young are perfectly formed they lie in a semicircular position and are delivered, usually tail first, one at a time, over a period of hours.
On birth, the fry falls a few inches through the water, but quickly straighten out and, if strong enough, make for cover among the plants. If these are not nearby, the fry sink to the bottom and take refuge in the sand, rocks or whatever other covers there may be.
They lie motionless for a short time while gathering strength. It is unnecessary, and in fact, inadvisable to have the male parent in the spawning tank. Once the female is impregnated, she can give birth to as many as five or more broods of young at intervals of four to six weeks.
The number of each brood may vary from 12 to 15 babies from a young Mollie to as many as young from a large swordtail. Most look like a miniature of the adult fish at birth. They are not only much larger than the newly hatched young of egg-layers but are also capable of swimming and looking for food and protection. In a few hours after birth, live-bearer fry can eat baby brine shrimp , daphnia and even finely ground dry food.
Many an aquarist has been surprised by new fish that suddenly appear in their tank this way! The largest single delivery of fry by a Guppy, as far as we know, was recorded by Paul Hahnel, the well-known Guppy breeder. Hahnel reports a brood of young from one female, although only of them lived to maturity. Myron Gordon found embryos in a large wild-caught Platy fish. Swordfish mature at six to eight months of age while Guppies are recorded as delivering their first brood when only 90 days old!

There are two types of viviparity in fish. In histotrophic viviparity , the zygotes develop in the female's oviducts , but she provides no direct nutrition; the embryos survive by eating her eggs or their unborn siblings.
