first year... you should be looking at him growing to about 30cm.... thereafter it should slow down.... my current aro is about 4+yrs old and about 40-45cm...
Yes we can draw generalities but of course growth rates are going to be influenced by things like feeding/diet, how much exercise the fish gets, water parameters/temperature and also tank size -- imo the bigger the tank they're in from early life, the faster they'll grow. My Golden Head (in 325g) is about 1.5 yr. old (I've had him for ~8 months) and is nearly 40 cm now, still growing like a sprout (but I wouldn't be surprised if this slows down in not too distant future).
However my Blue Base (in another 325g), same approx. age, hasn't grown quite so fast, she's currently ~35 cm (but she generally eats less compared to the GH and usually isn't as active, so not surprising).
Kashif, I think Galantspeedz and Islandguy have answered your question. I've no firsthand experience with Asian arowana as they are federally banned in the USA.
If this is supposed to address Tobias' first sentence, I assume you are saying "Arowana is harder to keep in a tank than any other fish".
IMHO, this would not be a correct statement.
And overall, your post is so curt and cryptic that it carries a negative overall value of a filler without substance, bro, especially when one provides an alternative point of view to the one they chose to quote... Albeit I think I know what you mean and I even agree with it that on average an arowana is harder to keep versus many other monster fish because it actively tries to bail the enclosure when it's too small, this is based on my assumptions and experience.
I may be way wrong here too with my assumptions. It'd be much better if I didn't have to ponder that much what you meant.

Haha, thanks guys. I think collectively, we have made up for the curtness and diligently explained Anthonyfish's post. Great MFK spirit here. Thank you.
Thanks you guys. I love how you guys treat a newbie something I didn't have on other forums. There is a banjar red Asian arowana available where I live. I didn't see the fish personally but the store guy told me he can get that one for about 300 dollars for a juvenile. Is this price tag ok? Also I think its me only who like silver arowana more because of their snake like body and they look to me the Chinese dragons from ancient times. The only reason I am not getting one is because of the tank size restrictions. They aren't expensive here. A very good size is about 100 US dollars only. Small ones are even less than 50 dollars. I am very confused between Silver and Asian. Want to own which isn't to aggressive and which I can keep for as long time as I can before re homing.
If you were in my shoes (and have to get an arowana because your heart is set on one) would you buy the silver because you love silver more or would you buy the Asian like banjar red because it grows slowly and doesn't grow so much. Please advise.
