Then again, GloFish Tetras or Danio will live peacefully in the tank without attacking others or their own species. They are peace-loving.
As a result, you need to know about the species and their characteristics first before keeping them in the tank.
Moreover, when they feel suffocated in a small area or sometimes when they feel there are too few or too many of the same kind of species in the tank, they can get all stressed out and attack each other.

So, now let us discover the reasons why GloFish feel aggressive and attack their own kind. My suggestion will be to take the necessary steps to eradicate those problems.
Why Does GloFish Attack Each Other?
In this part of the article, I will be sharing all the reasons that might cause GloFish to attack each other. There is nothing to worry about; I will also share a few tips that can help minimize the problem or completely eradicate it.
1. Congested With Fish
Sometimes the tank can get overpopulated with fish, and tha tank size might not be big enough to hold such a large number of fish. This can make the existing fish all stressed out and end up attacking each other.
Always remember every fish needs to be put in an ideal size tank, and the fish number should be within a range that helps them move freely.
Do adequate research before putting your preferred fish in the same tank.
2. Lack Of Food
The fish should be provided with an adequate amount of food at the proper time. It would help if you also make sure the fish in your tank gets the appropriate amount of food.
For instance, a few fishes eat food from the upper level of the water column. Then again, you cannot keep all the food on the top of the tank, as they might eat it all at once.
You need to make sure you are dropping enough food for the present fishes in the tank and make sure to leave some for the lower region fishes.
Some GloFishes can be pretty aggressive and take in all the food at once without sharing them with the tank mates. Or else they can get aggressive and attack each other.
Ensure the GloFish has enough food by maintaining a proper dietary chart and strictly following them.
3. Not The Right Type Of GloFish
GloFish, like Tetras and Danios, is a gentle fish. They are non-aggressive and tend to live all by themselves without hampering others.
Then comes the GloFish Bettas, who tend to attack other species. Betta Fish even thrive in their own kind.
If you want to check, just add two Betta fish in a tank; they will go after one another. They will hardly avoid attacking each other.
But when you put other types of GloFishes, you need to keep at least 3 to 5 from each species to make a proper balance. It will keep their stress level low and keep them in the friendly environment required.
That is, you need to make sure the tank mates are not harmful to each other, and there remains harmony between themselves.
4. Male And Female Unbalanced
The number of male and female fish should be properly proportioned. If there remains an uneven number of male or female tanks, the male fish will try to attack the other ones.
The male GloFish tends to fight and win over the female one. The male GloFish will also defend the particular territories that the female ones prefer.
The aggressive behavior can worsen if no female fish remains in the tank. As a result, experts suggest keeping more female GloFish than male ones in order to maintain the balance.
5. Water Parameters Not Sustained
Water parameters should be maintained no matter what the situation is. Each type of GloFish might require a different level of water parameters.
When the parameters are not sustained, it can cause stress to the fish, and they might end up hurting each other.
Use the proper kits like an aquarium heater to balance the temperature and an API testing kit to measure the pH level regularly.
