This largely depends on the species. I wouldn't risk it, as males can be aggressive occasionally, and all it takes is once....
"They will mate but if you keep them in there at the birth then the female will kill the male."
its sad but yes...
You can keep a female and male hamster together, but you must consider where you would home the babies if she has them.
You can not keep Betta splendens males together without them trying to kill one another. You can only keep a male and female Betta s. together while they are courting and spawning. Afterwards he will kill her if she is not removed. You can keep male or female Bettas with most other species of fish with no problems.
First you select a male for your female; or female for your male. Put them in a room together, but if the female is aggressive or the male is it's best not to. When they want, they will breed and keep repeating until the female is pregnant.
Yes. Don't keep males and females together.
It is not advised to keep them housed together. It is okay to put them together for a day or two for breeding, but if kept together they may end up fighting. The female will protect her babies after they are born and a male can also harm the babies.
just keep male and female amano shrimps together.
You can, but they will most likely fight, an probebly mate.
Yes
If you do they'll breed. Be ready to deal with that, or keep them separated.
you just keep them away from a male (if their a female) keep them away from a female ( if their a male)
