IMO for an arowana to really be happy it would take more then a 5' diameter tub. More like a 20' diameter pond with an abundance of overhanging tree branches and floating plants. These branches and plants would be stocked with part of it's food source. These fish are naturally jumpers and suppressing that would really keep them from being happy.
Now is this practical, no? So the aro gets the 5' tub. Space wise it is better then the 18" wide tank, but both are definitely lacking in providing anything near a natural environment.
BUT, wouldn't we all agree that it would be a much better situation if all Aro keepers had at least the 300 stock tank at their disposal rather than the "I plan on getting a bigger tank" excuse? Even then, the 20" Aro wouldn't be 20" for long, so your suggestion is much more in line with keeping an Aro for life.
