You can kill a beta fish by shaking it because you an cause physical injuries that can be fatal. The fish can also become stressed which can also cause death.
why would you want to kill a betta D:
yes betta fish have to live alone or one will kill the other.
yes
The Betta fish want to kill eachother. That's what all Betta fish want to do, that's a natural thing.
Betta fish are very aggressive. They pick at their scales and then they're gone!
No.
Yes, Betta Fish are extremely aggressive and they will most likely kill your other fish.
Np, but they will bite. Yes, they will fight to the death.
No...betta fish are usually aggressive and might kill the angelfish.
Well, if you love your Betta fish, then it should live by itself. But if you add another Betta to your current Betta fish's tank, then they will start a fight because Betta Fish are Siamese fighting fish and if one Betta is in contact of another Betta, the possible reason would be a fight between them two.
LOL. To be honest yes. But it will also kill the betta.
Male Betta's are solitary. They cannot be placed with other fish. That's why they are known a Japanese fighting fish. They will kill other fish for territory.
