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. Hardness: Arowana like soft water(not a lot of lime) but can also tolerate water with reasonable hardness.

You may want to check your the levels of lime in your water if you are considering becoming an Arowana owner

Water Change: The Arowana is carnivorous fish therefore it produces a lot of waste. If you do not change the water

regularly the waste will result in high ammonia and nitrate levels in the tank. This can cause death. It is highly recommended

that you change 30% of the water each week. If it is at all possible you should change 20% of the water twice a week.

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.
