No animal that is female can fertilize a female. Some animals are hermaphrodites, ie, male and female at the same time. Others, such as clownfish, can change sex. However, at the time of fertilization one clownfish would be male and the other female.
Answer
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.
She breeds with a male Betta Fish.
my fish also does that. Is your fish a male or female? If it is a female it is probably pregnant. Hope that helps!
they are spawners. they dont get "pregnant"
All that is needed is a male guppy in with her.
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.
No
It's impossible for a female to be pregnant. They are egg layers. Females can be eggy, though.
With a guppy you need to look at the gravid spot. This is a dark spot in the fish's belly. A large gravid spot indicates the fish is likely to be pregnant. You can tell how pregnant the fish is by how large the spot is. Sorry I have no experience with other species.
Sometimes.
NBo not unless you have two males and one pregnant female
