Situations That Make Glofish Tetra Aggressive
If you take good care of Glofish Tetras, then the possibility of aggression in them will be very low. Yet, if you notice some aggressive nature in them despite proper care, it is essential to know the reason behind it.
To help you out, I have summed up some situations that usually make Glofish Tetra aggressive or violent. They are:
Non-schooling Of Glofish Tetras
Glofish Tetras are schooling fishes. Meaning, you should put them in a group for their comfortable stay in a tank. They get support from one another that makes them grow better.
Here, if you put Glofish Tetra solely or in a group of less than 5 of them, there is a possibility of growing aggression in them. They get nervous and awkward quickly in such situations. It will eventually make them dull in the tank and later leads to aggressive nature.
Illness
Like in any creatures, illness is a common situation that builds up stress and anxiety in Glofish Tetras. Such pressure will further lead them to become aggressive and nasty.
Illness in Glofish Tetras may occur due to an unsuitable tank environment, lack of tank mates, lack of adequate diet, etc. However, sometimes, some genetic issues may lead to sickness in Glofish Tetras.
Mating Desire
The mating desire of Glofish Tetras has often led them to become more aggressive. If there are more male Glofish Tetras and fewer female Glofish Tetras in a tank, the male becomes more aggressive and attacks the other, competing for the female one.
The male Glofish Tetras becomes extra aggressive compared to female Glofish Tetras if their mating desire is unfulfilled.
Experiencing Bullying From Other Tank Mates
Glofish Tetras are peaceful schooling fish. They prefer staying active and cheerful in a tank. In between, if any fish species is offensive or dominating in the tank, the Glofish Tetras will certainly experience bullying from them.
Such an experience of bullying from other tank mates will surely trouble Glofish Tetra. It will eventually make the Tetra aggressive and toxic.
Overcrowded Tank
As Glofish Tetras are schooling fish, they prefer to stay in a group of at least 5. However, it doesn’t mean that you should put them in a large number without considering the tank size.
If you place your Glofish Tetras in a small or large-sized tank, but with numerous fishes, your Glofish Tetras tends to be irritated and aggressive slowly due to overcrowding.
Improper Tank Conditions
If the Glofish Tetras tank lacks to manage requisites like: pH level, water temperature, water hardness, clean water, lighting, decorations, fertilizers, etc., it will severely affect them. By the lack of such requisites, Glofish Tetras believes the tank environment is not safe and comfortable.
Thus, such thoughts make them to be self-protective, which later results in showing aggressive nature.
What Happens When A Glofish Tetra Gets Aggressive?
The aggressive behavior of Glofish Tetras is not a good sign. An aggressive Glofish Tetras affects not only itself but also its tank mates and tank environment.
Hence, here are some outcomes caused due to the aggressive nature of Glofish Tetras:
- An aggressive Glofish Tetra will suddenly chase, bully, and attack its tank mates.
