Plenty oxygenation, and filtration, keep up the water changes with conditioned water. One thing to be careful of with arowanas is when changing the water try to keep the temperature of change water as close to the tank waters temperature. Arowanas are hardy fish if everything is kept fairly stable. Salt can do wonders for them on short term basis, BUT they do not like stress, leichardti are naturally skittish, and can do damage to themselves when under stress.
