Arowanas need large tanks due to their size. They also require powerful filtration to maintain water quality. Water changes will also be critical to water quality since they produce a lot of wastes. Use only conditioned water that is temperature matched to prevent stress or shock. A home test kit should also be used to monitor water chemistry. Minimum tank size should be between 130 and 150 gallons. Adults will need larger tanks. Keep a cover in place as they are accomplished jumpers. They should be kept in "soft" water and, being tropical fish, maintain temps between 75 F and 86 F. Feed a varied and balanced diet including krill, shrimp, mealworms, nightcrawlers and feeder fish. Food can be fresh, frozen (thaw it first) or freeze dried. Lastly, these are aggressive fish, so tank mates must be chosen carefully, if at all.
