Pregnant Fish

[Ukfan]

Hi all, I want to know how you can tell if your female betta or female guppies are pregnant ?
And how all female fish are pregnant.


Cheers

Depends on the fish. some fish are live bearing, meaning the eggs were fertilized within the mother, and the fry are born alive and free swimming. The live bearing fish consist of guppys, platys, swordtails, mollys, endlers, and a variety of uncommon species such as the halfbeaks. Other fish like bettas utilize external fertilization, meaning the female lays the eggs into the water, and the male fertilizes them there after. from this point the eggs will develop and hatch in the water either with or without parental care.

Thats bettas and guppys for ya. There are many species of fish and they all have their own breeding habits. You can find more information on specific fish by going into the archived fish index board at the top of the board list. That should have all of the more common species listed, as well as how they breed.

Female betta's just carry eggs and release them to be fertilised when she encounters a male she likes, however due to the territorial nature of betta's towards each other succesful breeding is unlikely to happen if you are keeping a male betta with females all the time in a tank together. Check out the betta section of the forum- there are like a million threads on how to breed betta's and stuff etc, same goes for livebearer section of the forum with guppys.

Ah-cool guys, so when would you be able to tell if the fish are pregnaut?

I know with some they have a black mark near the anal fin?
