Are guppies territorial?

From what I have experienced some male guppies do tend to become territorial when younger guppies breach their surrounding area...it's very rare so there's really nothing to worry about.

wow that is a beautiful pic of your guppy, i tried to take some pics of my guppies and post them on my profile but they didnt come out very clear. I have never noticed my guppies to be territorial but i do know that you should have at least 3 females to every male, or the males may fight.

Not that I ever noticed. They all swimmed to swim wherever they wanted with no problem.

No they are not. Be aware though that if you have a male (prettier) and a female, you will end up with LOTS and LOTS of babies very quickly. They live birth so you don't have to have anything special for them to mate and give birth.

Not at all. They're one of the most peaceful fish I've ever owned. Watch a tank of them in a pet store.. very little space for each fish proportionately, and they still thrive and don't quarrel like other fish species do.

Guppies are not territorial but will "fight over the females. That is to say they will try to mate with as many females as possible so as to spread their genes to as many offspring as possible. As you probably know by now that the females will be able to produce up to 50 young per brood (at about a month interval) for up to about 6 months with only have being fertilized by one male.

I think no.
