How do I know if my fish is pregnant?
The area where a pregnant guppy’s abdomen meets the tail is sometimes called the “gravid patch”, or “gravid spot”. When pregnant, there is a slight discoloration that slowly darkens as the guppy progresses through pregnancy.
Do zebra fish lay eggs?
At the onset of the light cycle, zebrafish will generally initiate breeding behavior that results in the laying and fertilization of eggs. In a tank that has been marbled, the eggs collect between the marbles and escape predation. However, when no marbles are in the tank, the fish will rapidly consume the eggs.
Do zebra Danios breed easily?
Zebra danios are a favorite of freshwater fish hobbyists because of their ease of care. They are also prolific breeders and the easiest type of egglayers to breed.
How long does it take zebra fish to breed?
Although zebrafish reach sexual maturity in 10-12 weeks, the breeding fish should be between 7 and 18 months of age for maximum embryo production. Keep males and females in separate tanks with up to 8 females or 16 males per 10 gallon tank.
How do you tell if your fish is pregnant or just fat?
Carrying Eggs – One reason your fish may appear slightly bigger is because it is carrying eggs. If your fish is a female, is not overly fat, and is normal in most other regards, this is a very high possibility. Another indication is if your fish has an enlarged vent; this is where the eggs will come out.
Are zebrafish babies live?

How do zebra fish reproduce?
As the males chase the females around the tank, they stimulate spawning of eggs while releasing sperm into the water for fertilization. Wait approximately 15 – 30 minutes after pulling a divider to give the fish time to mate.
How do you get zebrafish eggs?
Embryos can be collected once a week, with best results from tanks kept on a regular schedule. Collect embryos and fertilized eggs from between the marbles with a siphon and collect with a fine fry net or mesh filter.
How often do zebrafish breed?
It has been reported that an optimal breeding frequency for zebrafish is every 10 days (Niimi and LaHam 1974). If fish are not spawned often, eggs are reabsorbed in the female fish.
