Some male betta fish are not as aggressive as others.
Yes they will.
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.
No, because they are fighting fish and one of them will kill the other.
The male Betta will only fight another male Betta. They are slow, timid and peacefull fish except when another fish of the same sex and species is in the same vicinity.
The male Siamese fighting fish (or Betta splendens) will only fight with another male of the same species. Under normal circumstances they are a quiet, slow moving and peacefull fish. It is only when another male of the same species is introduced to its tank that the Betta becomes territorial and aggressive.
No fish will really fight a Betta,unless its another Betta(male,not female,males and females get along pretty well),so i would suggest getting a Gold Mystery Snail if you dont want your Betta fighting with your fish.
beta fish are very territorial if there is plenty of room for both of them in a tank they will just leave each other alone and another reason is that they haven't had to compete for food
Male Betta fish make bubble nests when they are happy ^^ I have only had male Betta fish and after a day or two of playing with them and feeding them or even just talking to them they make their nests to show you that you made them happy.
Just watch how they interact and if the betta is being aggressive isolate him. Bettas can be with other fish as long as the betta is a different color and there arent any fish with similar fins.
The axolotl would probably rip bits off the Betta and kill it. Male Bettas are quiet peacefull fish and they will only fight with another male Betta.
Beta fish do NOT like other fish, they may try to kill the other fish or get seriously injured by the other fish.So probably not.
No they can not. Some people call a Betta splendens a Betta or a Siamese fighter or a Japanese Fighting Fish. They are all refering to the same species of fish. They come in both males and females and both are needed to produce any young.
