In the wild, their aggression helps them defend territory, but in confined aquariums, this can escalate, especially in male-against-male situations, leading to potentially lethal fights. The intensity of their behavior can vary between individual fish, but it’s instinctual. To prevent conflicts, owners shouldn’t house two males together. They should take effective steps like using dividers or keeping them separate, as even being able to see each other can provoke displays.
Reasons Betta Fish Fight With Other Fish
Betta fish, also known as Siamese fighting fish, are well-known for their aggressive behavior. This aggression isn’t just a random act—it serves multiple functions. Territory, food, and resources are the primary reasons why these fish fight. Betta fish are innately aggressive, particularly the males, who can be competitive due to their history as fighters in Thailand. Fish raised in isolation have more aggressive tendencies. In an aquarium setting, it’s critical to determine the right tank size to avoid severe fighting, which can affect welfare.
Female Betta Fish
Betta fish fights can also be a **consequence of trying to establish a harem or sorority within the tank. Females are generally less aggressive compared to males but still have some competitive tendencies. When housed with other females or even a small male sorority, they may engage in fights to establish a specific function in the tank’s hierarchy.
Kinds of Fish Do Not Fight With Betta Fish
Here are some fish that usually get along with bettas:
Corydoras (Cory Catfish)
- Peaceful bottom-dwellers who mind their own business.
Kuhli Loaches
- Worm-like fish that stay at the bottom, out of the betta’s way.
Ember Tetras
- Small, gentle fish that swim in the middle of the tank.
Snails (like Mystery or Nerite Snails)
- It’s not fish, but it’s a great option to keep the tank clean without causing trouble.
Every betta has its personality, so it’s important to watch how they interact at first
Betta Fish Fight Their Reflection?
Yes, betta fish often fight their reflection! When they see their reflection in a mirror or glass, they think it’s another fish. They flare their fins, puff out their gills, and may even try to attack the “other fish” to defend their space.
This behavior can stress them out, so it’s important not to let them see their reflection for too long. A little exposure can be fine (like a minute or two) to keep them active, but too much can make them tired or stressed.
How Long Does Betta Fish Fight?
Betta fish, especially males, can fight intensely. These fights usually last between 30 seconds to a few minutes. In their natural habitat or in a controlled environment where they are kept separate, they will often fight to establish dominance or defend their territory.
How do Betta Fish Reproduce if They Fight?
Betta fish reproduce through a unique process. The male attracts a female with bright colors and fin displays. He builds a bubble nest at the water’s surface and dances with the female.
FAQs
- Do Betta Fish Always Fight?
No, betta fish don’t always fight, but they are known for being aggressive, especially the males. Male bettas will usually fight other males to protect their space. If two males are kept together, they may injure or even kill each other. This is why people often call them “Siamese fighting fish.”
- What if I don’t see them fighting?
Even if you don’t see any fighting, bettas might still be aggressive. They could be showing signs like flaring their gills or chasing each other. Keep a close watch on their behavior.
- Can female betta fish live together without fighting?
Yes, female bettas can live together if the tank is large enough and has plenty of hiding spots. Some minor fighting might still occur, so it’s important to keep an eye on them.
- Are baby bettas aggressive?
Baby bettas can show aggression as they grow. They might fight with each other over space or food.
- How should I deal with an aggressive betta in a sorority tank?
If you have an aggressive betta in a sorority tank, move the aggressive fish to a separate tank. Ensure the sorority tank has enough space and hiding spots to help reduce conflicts.
Conclusion
Betta fish are naturally aggressive, particularly the males, which can lead to fights in confined spaces such as aquariums. These fights usually occur due to territorial disputes, competition for resources, and hierarchy establishment. To prevent conflicts, it’s important for owners to avoid housing two males together and to use dividers or keep them separate if needed. By creating a suitable environment with enough space and hiding spots, betta fish can coexist more peacefully and live healthy lives.
