k thanks for helping but pls tell me prevention for eye drops and which food is good for him for growth and colour im giving him arowana pellets is this good or something else
In 6 to 8 months, your aro will reach 2'.
There is no definitive proof as to what causes drop-eye, but silvers almost always get it, especially the farm-bred ones. I did everything I could to keep my aro from getting drop-eye... feeding light meals every other day, no tank mates, no bright light from above, and it still got drop eye. It's just an issue with silvers. Black aros look very similar but almost never get DE, so you could get one of those instead.
I'd feed anything from Hikari for carnivores. Occasionally I'll feed shrimp, worms, crickets, krill, etc.

Nothing you can do to prevent drop eye, unless maybe raising in a natural pond setting.
Properly kept, your arowana will grow 1-1.5" per month on avarage. So you will have about a year, though heavy feeding could result in even quicker growth. Arowana should be kept in a tank that is minimum, at least 3 times their length long and at least equal their length wise. This means the the arowana will have outgrown your 150g tank well before it reaches the 24" length, though I don't know the exact dimensions of your 150g tank.

the experts may be right about DE, but i got an opinion too
in an aquarium they got nothing to look up at!!
if the aquarium is low, even worst, they gotta look down at the other fish and even lower at our feet moving around.
i would have floating plastic or natural plants, other surface tankmates such as gars & archers and keep the aros vision at the same level as yours.
my silvers grew up to 21", they all suffered from it, but not severely...1 of them had it slightly on 1 side only!

But then why is it uncommon in other species of arowana, even if housed in the same tank?
I try to stay away from DE discussions, they always seem to turn bad. 
This is my take, Silver aros are more apt to getting DE due to gentics, whether is be from capative breeding or just naturally in their make up. Do to the environment of an aquarium silver arowana do not exercise their eyes as if in the wild, likely adding to the cause. In many cases that have been experienced by silver arowana owners, DE develops rapidly proceeding trauma to the head, from either jumping out of the tank or ramming into the top or side glass. In the wild it is possible that silver experience the same, though because they don't the lack of use/exercise of the eyes as in an aquarium, they can recover from it.
