You'll get a lot more help from CFC when he comes online, but he's probably sleeping so i'll help you as much as i can....

Firstly, i don't believe any arowanas can share the same tank, they are quite territorial and need a lot of room, the reason they were fighting, a full grown silver arowana needs a tank of at least 350 gallons (US), and thats for the one fish! So i would say they are a fish to stick away from full stot, returning them both would be best unless you actually have a tank that size in that case you should return the one....

What else do you have them with? and how big is your tank?

As Doggfather has said silver arowanas are BIG and territorial, a minimum of a 8x3x2' tank is need just to keep one and to keep more than one arowana without them killing each other you will need a huge tank and a minimum of 4 arowanas, 5 seems to be the preffered number for people who keep mulitiple arowanas.
I suggest returning one or both arowanas to the store they were bought from.

Hello,

Doggfather is quite right that Arowana's are territorial fish. But if proper attention is given, they are gentle as a Cat.

the only option you can do are....

#1) either you separate both Silver Arowana...

#2) or you buy 3 more silver arowana...

You cannot keep 2 to 3 to 4 arowana in one tank. But you can keep a minimum of 5 to 9 arowana's in a tank. Depending on your tank size.

if your tank is small, I would suggest you add a few filter, like an internal power filter, an overhead power filter and maybe a sponge filter.

Also you must do a 30% water changed everyday, if you have 5 arowana's in a tank. 15% in the morning and 15% in the evening...before you sleep.

and remember the Ph level...it must be around 6.
