Only if there is one in a tank they get very fisty , they will bite other fish in your aquarum .
Any fish may fight/bite if they are in cramped conditions and/or poorly fed. Guppies are not regarded as fighters but may sometimes do a bit of fin nipping of any fish with long flowing fins including other guppies and Bettas.
That's how guppies usually behave. They may well have a bit of rivalry but they will do no real damage.
Almost any community fish will do fine with guppies. Bettas are not a good idea with guppies because they will fight each other.
They usually don't, but guppies have differing personalities, with some being more aggressive than others.
They won't fight, they will try to avoid the males sometimes because the males constantly follow the female. They will fight if they want to. Males don't constanly follow the females. I have seen my guppies fight, but they wont kill each other. My guppies never fallow each other unless if they want to mate. It takes a couple of seconds to mate then they stop following each other.
Guppies are a community fish and are best kept in odd numbered groups with more females than males; for example, a group of 3 guppies with 2 females and 1 male. The reason for a higher female to male ratio is because males will fight with each other for matting rights to the females.
Fries (the term for baby guppies), are eaten by older guppies, but guppies are eaten by fish like tuna.
Only guppies breed with guppies naturally.
