This depends on the type of fish
New answer
You could isolate the fish by placing it into a nursery tank so that the other fish do not eat her eggs or young fish as they hatch.
A pregnant fish is called a TWIT
Parrot fish do not get pregnant so there is nothing to do.
1 to 2 months
A guppy fish is pregnant for about 4 weeks.
When you hold the fish it will say what kind its status(which will say pregnant) and age
have sex with a fish and get it pregnant
Although there are fish that live birth, goldfish are egg laying fish, and as such, they do not get pregnant.
nothing![although, dont let the other fish eat the pregnant one]
You can do one of three things. 1. Leave the pregnant fish alone in the main tank and just let the pregnancy happen. They baby fish will probably find hiding places themselves. 2. Get a breeding tank. Leave the pregnant fish in the main tank and then when you see a fry, net it, and put it in the breeding tank. 3. Get a breeding tank and put the pregnant fish in it and just leave it. Whenever the pregnancy is over, put the pregnant fish in the main tank but leave the fry in breeding tank.
Fish actually can not get pregnant. The female fish drops her unfertalized eggs in the water and a male fish swims past and fertilizes them.
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
No.
