The feamale became larger but you need to condition her before.Conditioning is made by feeding the fish live or frozen foods about two to three times a day, and making frequent water changes. Conditioning should take about two weeks at least, and can take up to one month, depending on the food quality and water temperature. The breeding set-up, in both ways, should contain lots of hiding places for the female, and some floating plants for the male to build its nest. If floating plants aren't available, you can use a halved Styrofoam-cup. Water temperature at the breeding set-up should be in the range of 28-30oC (82.4-86oF/ 301-303oK), and it is advisable to place a tight fitting glass-cover on top, so that the air above water will be hot and humid.
they are spawners. they dont get "pregnant"
She breeds with a male Betta Fish.
It's impossible for a female to be pregnant. They are egg layers. Females can be eggy, though.
a female Betta is always pregnant!! But u will start to notice vertical lines on its body like this!!!!!!!!!! not like this ---------. if they are horizontal then your fish is stressed out
No.
Np, but they will bite. Yes, they will fight to the death.
yes
it looks like they have a big bubble in their side
No. Betta fish will attack each other no matter the sex.
Yes they will.
Your betta fish is a female if she has smaller fins than an average male.
The Betta fish want to kill eachother. That's what all Betta fish want to do, that's a natural thing.
