Please get a bigger tank for your Arowana fish (they need about 150 gallons of water and 4 ft aquarium to move freely) and manage the temperature of your aquarium by using a proper aquarium heater. They do suffer in short spaces (they barely survives). Please provide him a good aquarium with good space and aquarium heater to regulate the temperature
