what is a good size tank for an silver arowana?
Answers:
u will need a large tank, adult silver arowanas will get huge, in the amazon they will get well over a meter.
The problem is, they need a tank to turn, it must be large/wide enough for them to turn.
Try looking for something about 300 gallons for a adult. It is large enough for the fish to swim and turn.
Remember to keep a hood and a tight one, as they are powerful and skilled jumpers.
You can keep small ones in smaller tanks, but when considering these fishes, you will need a large tank for the adult to turn.
I would say as big as you can possibly afford ... they can get HUGE ... they're rather nasty, aggressive fish and can't be kept safely with other fish ... are you sure you really want one?
Get a tank thats 200g+ don't worry about how tall it is but more of a surface area one, at least 96" length and 36" deep. height doesn't matter.
All I can suggest is a very large tank since a Silver Arowana can reach a maximum size of 48"+.
