They primarily feed on small invertebrates, algae, and plants, so they don’t rely on aggression for survival. However, some guppy owners have reported more violent behavior in their tanks. This may be due to overcrowding or a need for more hiding spots for the fish to reduce stress levels.

Generally, when too many males are kept together, this tends to cause aggression due to competition for mates; females usually retreat when threatened.

Therefore, aquariums must provide sufficient space and hiding spots for their fish if this potential aggression is to be avoided.

No, guppies are not naturally fin nippers. Contrary to popular belief, guppies can become fin-nipping given the right circumstances, such as overcrowding and stress.

Guppies nip each other’s fins because when confined in a small space, they display aggressive behavior, which may result in them biting each other’s tails or fins, leading to injury and infection.

To ensure that your guppies stay healthy and peaceful, it’s best to provide them with plenty of room to swim around in their fish tank – at least 10 gallons per 4-5 fish is recommended – and make sure all parameters like pH, temperature, and nitrogen cycle levels are maintained at optimal levels for the species needs.

Provide Hiding Spots

Another reason male guppies may be chasing each other is to attract females ready to mate.
