Although not as striking as its Asian cousins, the South American silver arowana is full of personality and looks stunning when allowed to develop to its full potential.

Here is another good article which among, other things, states:

The drawback in keeping these fish is their size. Even aquarium specimens attain around 90cm/36”, and wild fish can be larger still.

Some sources cite a 240 x 90 x 90cm/95 x 35 x 35” tank as sufficient for a single adult, but not everyone would agree. Based on the ‘six times’ rule a 6m/20’ tank is required, which eliminates nearly every private aquarist, aside those with tropical ponds.

The above is from Practical Fishkeeping magazine from their article,
