Betta splendens do not get angry with people. If you think your Betta is angry with you it will be your guilty concience. I advise you to look after your fish well. Give it good food, good conditions and change its water regularly and thereby have no conscience pangs.
NO!!!!! They should not eat betta fish...but if your cat has then call a vet, and don't get anymore betta Fish!
I believe you mean Betta fish. No, it should be fine. You can treat you Betta fish by giving them bloodworms!
it depends on if they have egg's in there but if not they don't get angry.
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.
If you want an active fish that moves around a lot then a Betta is not for you.
Betta fish get in fights with fish with colorful fins and bodies. If your betta gets in a fight while your away,the weaker fish may die. But if you see your betta fight with another fish you should try to split the two fish apart [or all the fish that are fighting].
You should feed your betta 3-4 times a week.
other Betta fish and the bigger fish.
Betta fish do not eat fish.
No betta fish are carnivores.
Female Betta fish can be fairly good community style fish and should be fine. Male Bettas would massacre the community.
That's perfectly normal for a betta.
