How do you know if Arowana is stressed?
The physical signs of a stressed-out Arowana can be challenging to miss. The most common are color changes.

Arowanas are usually live alone, but it is not uncommon to see a couple of Arowanas in the same tank. Some even keep these fish with other species.
While Arowanas are not aggressive, they can get territorial when stressed. When this happens, they may start biting the fins of other fish in the tank.
Sleeping on the bottom
Arowana is a fish that likes to be active and they normally like to swim near the surface.

Ways to calm down a stressed-out Arowana

The most important thing to remember is that they need plenty of space and good water quality. Ensure your tank is big enough and has plenty of hiding places for the fish.
Below are some of the actions you can take to reduce the stress in your Arowana fish.
Adjust the water conditions

Acclimate the fish to new water conditions

Increase the number of hiding places

Transfer the Arowana to a larger tank
