Although Arowana is relatively large in size, it is not very daring and is easily frightened at ordinary times. There are many reasons why Arowana is frightened, such as sudden violent sounds or vibrations around it, sudden appearance of someone in front of the fish tank, hard beating of the fish tank, sudden brightening or dimming of the surrounding lights, etc. If the Arowana's shock is not serious, the breeder only needs to keep the surrounding environment quiet and wait for a few days before they can recover. If the Arowana is seriously frightened, the breeder needs to seal the top of the fish tank to avoid the Arowana jumping into the tank. After the Arowana's shock is relieved, they can try to feed them with their favorite food first. If they still don't eat, they can wait for a few more days.

There are many reasons for Arowana's indigestion, the most common of which is overfeeding. Breeders can stop feeding first, then raise the water temperature to above 26 ℃, and then change a small amount of water to ensure clean water quality. This can accelerate the metabolism of Arowana and relieve indigestion. If the indigestion of Arowana is serious, the breeder needs to stop eating, heat up, change water, and then feed some probiotics or Xiaoshi tablets to promote the digestion of Arowana. In normal feeding, it is best to choose digestible food, which can avoid indigestion.
