i have a pregant crayfish and i am wondering how long it will take until she has her babies?
Lobsters are not mammals, so do not become pregnant; they are egg layers.
Crayfish don't "give birth" they lay eggs.
It takes around 3 - 4 weeks for a platy fish to give birth.
It took the ones in our science class about a month or two.
she doesn't give birth - she lays eggs. :o)
Molly fish do not lay eggs. They are livebearers and give birth to fry fish. If there are eggs in an aquarium with Molly fish, then they belong to another fish.
If your talking about how long the gestation period (how long it takes from one birth to the next) then it's about 4-6 weeks.
whale is a mammal so it does not lay egg but give birth.
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.
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
A mickey mouse fish is prego for 4 wekks exactly.
Mickey Mouse Platys don't lay eggs. They give birth to live fish.
a long time
An average of 42 days is the time is takes for a ferret to give birth.
