1. Breeding separately: The thunderfish is irascible and has a strong sense of territory. If the breeder wants to completely avoid them fighting, it is best to choose to keep them separately.

2. Replace the big fish tank: If the breeder does not want to separate the thonorosaurus, he can prepare a bigger fish tank for them. In this way, they can have enough space to move, and they can also reduce the situation of fighting.

3. Add partitions: If there is enough space and fights will occur, breeders need to add transparent partitions in fish tanks. In this way, even if the arrowana wants to fight, it can't break through the partition. After they are fully familiar with each other's existence, they can try to remove the partition, so that they will also reduce the fight in the later growth process.

If the thunderfish is not seriously injured in a fight, the breeder only needs to add crude salt in the fish tank to ensure that the wound is not infected. Because minor wounds can be recovered by their own resistance, they don't need to be treated with drugs.

However, the attack power of Tronayana is strong, and its personality is very irritable, so it may be seriously hurt when fighting. When they are seriously injured, breeders need to use anti-inflammatory drugs such as potassium permanganate or penicillin to treat them. And during the treatment, breeders should keep the environment stable and avoid them being affected.
