As to size, Heterotis niloticus reaches over 3 feet and is a BIG fish, weighing over 20 pounds easy. As far as food goes, they eat little things, like small crustaceans. Something Daphnia magna in size would be about right. They are a riverine species, so you can bet the water they live in is around neutral and fairly soft. Think Kribs as far as water params.
They're only Arowana in common name, as they are another family entirely.
You would need an aquarium of prodigious dimensions to keep one, and be capable of maintaining top water quality, limiting Nitrogenous waste as much as possible. Keeping a large fish like that alive and healthy for is 10 to 20 year life span is truly a challenge.
I DEEPLY encourage you to do serious in-depth research and be able to shoulder the financial commitment keeping such a fish demands. H. niloticus is not for the casual fish keeper by any means.

I currently own one about 15" that i got when it was 2". These have a very high metabolic rate when small and a very small "throat" so if you plan on getting a small one they are very time consuming and have a very high mortality rate in tanks. If you find a larger one 10"+ expect to pay a lot for it because of the time and trouble it takes to keep it in good health as a fingerling. Like Dave said they do require a large tank and are very very active spending most of its day looking for food. They should also have a smooth sand bottom since this fish has a gizzard and will swallow some sand to help it break down its food.

I love mine and its a great fish. If you have the tank requirements and the willingness to take this fish on let me know and I can give you a lot of tips on growing out a small one.

Here are a few pics of mine.

About 8" in the second grow out tank (with white sand)

Less than 24 hours later after being moved to a tank with black sand.

At about 14" a few months ago

you can feed them guppies...rarely do arrowanas eat pellets but if you get one out of the batch that eats pellets, your lucky:]

Mine has been giving the hardest time out of any fish i have ever had. first i couldnt get him to eat, even tho the reason i picked him was cause he was eating at the store i got him from so i thought that was a great one to get. Then he gets a fungus and its starting to clear up very nicely and is get good fin groth. I got him at a very small size as well 2"- 3". couldnt love him more tho even if hes the biggest pain!

I think i like the bright white look better then the black look, dont get me wrong the black is very sharp looking but the white just glows!
Great looking Arowana!
