1, anal fin deformation: guppies in the process of reproduction, anal fin often deformed. The anal fin is round before pregnancy, square after pregnancy, and smoother when waiting for the birth of small fish.
2. Discoloration of fetal spots: When guppies are pregnant, the fetal spots are transparent, but they often turn black before giving birth, which is also a sign of preparing to give birth to small fish.
3. Abnormal behavior: Any fish in the breeding season will have relatively abnormal behavior, and guppies are no exception. It is relatively quiet, but before the birth will be very irritable, usually away from other members of the same kind, hiding in a place to wait for the discharge of eggs.
Under normal circumstances, guppies usually breed once a month, and twice in three months, which is slightly slower. Because of different species, the number of reproductive mantissa is not the same, some can produce about 10, many up to 120. Its sexual maturity period is 3-5 months, long half a year of small fish can reproduce the next generation, and reproduction is not affected by the season, can be carried out throughout the year.
Female guppies with good species are selected as parent fish and put into a fish tank for propagation, and the water temperature is controlled at about 25 deg C. Male fish to the breeding season will chase the female fish to complete the mating, usually four weeks to produce once, because they will not take care of the young fish, but also may appear to swallow the phenomenon, after spawning to fish out in time.
