Hi all, wanna ask..if a arowana didn't eat for more than a week n look inactive ( slow moving, less moving) later on dead ? What reason due to this situation ?
There's a lot of reason why your aro acting like that.
One common thing is, migration to a new tank. New tank need time for your aro to adapt BUT If your aro already in the tank for months, it's probably because of the water parameter like Saif said. Check your water PH & chlorine.
Check your aro behaviour, may be of the tank location, lot of people walking across close enough to the tank also can cause trauma to the fish.
For arowana, tank location is totally important because the fish can easily get shock when somebody or something walk too close to the tank. Don't ever place your tank outside your house. What i meant here is don't place your tank in the porch area.
Trauma play a big part to your fish and need months too calm it or to tame the fish. Flash of lights also can cause trauma to the fish.
There's a lot of item to check water PH, chloromine level & chlorine level.
Sometimes we use black water to calm the fish.
Just let the fish for few days more. If nothing wrong, please check what is the last item your add to your aro tank. For example active carbon.
All the best!
