Arowana is not a difficult fish to keep. After all, it has survived throught millions of years until man came into its way. All you need is to spend one to two hours p
pH: Althought arowana can withstand a reasonable range of pH, they should be kept in water that is slightly acidic or neutral. Make sure you check you pH regularly, especially if you have something in your setup that will altered pH, eg peat, CO2 system(in planted aquarium), etc.
Temperature:Water temperature should be maintianed at between 26C-30C(79F-86F). Avoid sudden change of temperature as it may chock the fish can cause problem like tail dropping. Although arowana can withstand higher temperature, this is not recommanded especially if it is for long period of time. High temperature cause wrinkling of the gill cove and destroy the authentic look of the fish.
Arowana is carnivorous fish. they produce large amount of waste. High amonia, nitrite and nitrate are common problem in arowana tank. Regular water change is the easiest way to deal with it. 1/4-1/3 water change per week is recommanded, 20% twice a week is even better if you have the time. Make sure you adjust the temp and pH of the new water similar to the tank's. Sudden drop of temperature or pH is dangerous and could sometime proved to be lethal.
