Well if u get them from the pet store then they will tell u but if not then u need to get them a blood test
yes they can.
I don't think so.
Fighting Fish do eat each other so, yes
no you can not put a female and male fighting fish in the same tank because they will just kill each other
Some male betta fish are not as aggressive as others.
No. The females will kill each other.
no because they will end up killing each other
The male of the species has brighter colours and is a much larger fish than the female
First of all, male and female fighting fish (bettas) shouldn't be kept together. They are both territorial and agressive. They may be fighting over territory. It may also be that the male is ready to mate and the female isn't.
It all depends on the length of the fins. If its long its a male if its short its usually a females the exotic colors can help you tell as well. This is for any kind of fish, but mostly for Japense fighting fish and Feeder fish. if you have any other qustions you can contact me at, holly.mello@yahoo.com
They do not normally get a chance to pick. The male will kill her if she will not or can not spawn with him.
Yes they will.
