yes after mating a female will be tired and hungry and if the male does not run her away she may eat the eggs for energy.
It is courtship but be careful during the mating the male will kill the female then the male will make a bubble nest. When the babies hatch be shure to separate the babies or they will eat each other hope this helps
Yes
No, probably not. The males would be more likely to kill the females.
The male will protect, tend, and clean the eggs after they have been laid. It's best to remove the female right after mating and the male after the babies are free swimming (3 or so days). The female will die if she is left in there and you could risk loosing your babies. Also after the baby's have hatched remove them from harm of the female or male. They will both tend to eat the fry's, or baby's.
My sugestion is that you sell them because the female wil try to eat them and the male will kill the female and you will loose you female betta fish so give them to a pet store or sell em
Betta fish do not eat fish.
a male Betta will usually like the company of other fish but will fight or kill others of their kind also they might fight guppies cause they look similar to a female Betta.
If there is a male and female beta fish, the male probably ate them, and those 2 unlucky babies were definitely male. (male beta fish will kill other fish.)
No, they will not fight. Bettas are normally a very slow moving, peacefull fish. A male Betta will only fight with another male Betta. The crayfish (depending upon its species) is likely to rip pieces off the Betta and maybe kill and eat it too.
Most fish get along well. However, do NOT mix betta fish with other fish. Not even another betta. You have to have a permit to have to betta fish in the same tank with eachother. Betta fish are only mixed to mate. Bettas are not born in the egg. They come out as a very small fish. After the betta babies have come out, all of the fish are seperated. Even the parents, if the betta babies are left in the tank with the others the betta parents are very likely to eat the others.
No, probably not. The males would be more likely to kill the females.
You can try to put Guppy fish in with your Betta fish. That would be one of the only fish that i would put in with my Betta fish. I say that because i have a Betta male and he is OKAY with guppies. the first guppy i put in his died to to getting picked on by him but the others did not, so just give him another chance if you decide to get guppies. Hope i helped!
