Average growth for silver arowana is 1 to 1.5" per month. Growth spurts of upto 3" per month are not that uncommon. This growth rate is seen upto around the 24-25" mark and then their growth slows to a couple inches or less a year. So figure within a year your arowana will be at least 15" and in need of a new tank. Realize though that arowana could reach that size in as little as 8 months from now, or even sooner.
