Well, darling, a fighting fish, also known as a betta fish, doesn't have an IQ because they're fish, not scholars. So, in short, their IQ is a solid zero. But hey, they may not be the brightest bulbs in the fish tank, but they sure are pretty to look at!
No, fighting fish (Bettas) are only interested in fighting with other fighting fish.
Of course they can. How else would we have fighting fish.
'Japanese fighting fish' 'Chinese fighting fish' 'Siamese fighting fish' and 'Betta' are all names given to the 'Betta splendens'.
Fighting Fish do eat each other so, yes
yes allchinese fighting fish fight
yes if not how its fertilised
they do fight.
Fighting fish is their nic-name so they should be kept separate
I don't think so.
No fighting fish eat when ever they get the chance.
Win what? be more specific. If you mean in a territorial dispute, an adult fighting fish will get eaten (literally) by and adult convict cichlid. but if the cichlid and the fighting fish are of the same size then the fighting fish would be at an advantage.
When your fighting fish is about to give birth, it will have a white extended belly.
