How can we stop guppies from chasing each other?
We now know that chasing is normal in guppies as they chase for many purposes.
But, constant chasing can happen for many reasons that we can prevent.
Perform these things to stop your guppies from chasing each other:
- Provide your guppy big size tank
- Maintain a male and female ratio of guppies.
- Avoid overcrowding your guppies aquarium.
- Provide your guppy an adequate water condition.
- Ensure feeding your guppy, high-quality nutritional food regularly.
Big size tank
Guppy fish need ample space to live comfortably.
You should consider keeping guppies in a big size tank.
This way, you can prevent guppy from coming under stress because of lack of space to live comfortably.
Maintain male and female guppy ratio
Maintaining the male and female guppy ratio will prevent chasing in guppies.
We should keep male and female guppies in a ratio of 1:2, which means one male guppy and two female guppies.
You can also keep one male guppy and three female guppies.
Keeping your guppies in this ratio will help your female guppy.
When we keep more female guppies than male guppies, the stress because of being chased by male guppy for mating gets distributed among female guppies, and they get time to calm down.
Avoid overcrowding your guppies aquarium.
An overcrowded tank will make your guppy fish come under stress as they will not get enough space to live comfortably.
Also, an overcrowded tank will get polluted faster than usual.
Oxygen will be deficient in an overcrowded tank.
These will put your guppy fish under stress, and chasing can happen.
So, to make sure that you are not overcrowding your guppies tank, follow the one-inch one-gallon rule.
The one-inch one-gallon rule means one inch of fish per one gallon of water.
