would lowering the water lvl of the tank make aro want to jump more or less. my first aro RIP b/c of jumping. its only 10inch, had 5 inch space between water and the top of the tank and still jumped out.
jumping depends on the individual aro I have one that never has jumped for anythin and I have had two in the past leap tank and found on the floor dead.. but keeping the water level full is optimal
