Start by providing them with plenty of hiding places, and make sure the tank is well-planted.

At first glance, the answer might seem to be a straightforward yes. After all, guppies are known for their spirited and sometimes territorial behavior.

But is this really the case when it comes to female guppies? A recent study seems to suggest that, in fact, the answer may be no.

The study was conducted by researchers at Pennsylvania State University and involved observing groups of both male and female guppies in their natural habitat.

What they found was that, while male guppies tend to be more aggressive than females overall, this aggression is typically directed towards other males rather than females.

In other words, while female guppies can certainly become aggressive when defending their territory or food sources, they are not typically as fierce as their male counterparts.

Do Guppies Bite

This question has puzzled aquarists for years. Some say that guppies will bite when they’re threatened or angry, while others believe that guppies are gentle fish and won’t bite unless they’re provoked. The truth is that guppies do bite, but it’s not very often.

Final Words

In conclusion, guppies are not typically aggressive fish. However, there are some instances in which they can become territorial and aggressive.

If you are thinking about adding guppies to your aquarium, be sure to keep an eye on them and their behavior to ensure that they don’t pose a threat to other fish in the tank.
