I am guessing that you are refering to the "Siamese Fighting fish" Better (more acurately) known as a Betta splendens. They do not have live young and so can not get pregnant. The male builds a nest of bubbles and looks after the eggs and fry in there until he decides they are capable of hiding and fending for themselves.
You should name your Chinese fish Martha or in Chinese maratharatia!
A pregnant fish is called a TWIT
Parrot fish do not get pregnant so there is nothing to do.
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
鱼yu
Although there are fish that live birth, goldfish are egg laying fish, and as such, they do not get pregnant.
the Chinese beta fighting fish
a fat orange Chinese fish
nothing![although, dont let the other fish eat the pregnant one]
