guppies stay pregnant for about a month before giving birth, other fish take longer, and others lay eggs (don't get pregnant). depends on the fish
Parrot fish are a man made cichlid. They did not evolve in nature but were made in a laboratory. They lay eggs so they can not get pregnant.
Most fish do not get pregnant in the same way that mammals do. They lay eggs instead of carrying developing offspring internally. The time it takes for fish eggs to hatch varies depending on the species.
Zebra danios are not live-bearing fish, so they do not get pregnant. Instead, the female will lay eggs, and the male will fertilize them. The eggs will hatch about 2 days after being fertilized.
How can gold fish breed how long does it take what can we do to help them
Grasshoppers lay eggs, they are not pregnant.
Well, despite the name, it is not an eel, but is a fish. Like other fish, they do not get pregnant and do not have a period of gestation. The female lays eggs, which are fertilized outside her body.
Neon Tetras are egg layers/scatterers and do not have babies. They can spawn every two weeks when conditions are right and they are also in breeding condition. They lay hundreds of adhesive eggs when they spawn.
Swans lay eggs, so they do not get pregnant.
The fish don't lay eggs. They give live birth; they are pregnant for about 20-25 minutes. Than after that they start swimming around the tank. They are small and white so for some people they are hard to see. But not for me. So yeah, hope i helped :)
Peahens do not become pregnant, they lay and sit on eggs.
No time at all. Bettas can not get pregnant. They are egg layers and their eggs are kept in a nest of bubbles at the surface of the water and looked after by the male Betta until they hatch and become free swimming fry.
