My Arowana is becoming mean. What to do?

[snow]

When my Banjar Red arowana was under 10" he was very nice and got along with everyone...now it a different story. After the 10" mark(he is now between 13-14") he is attacking some fish in my tank. Right now he is turning on my 12" oscar, making his fins ripped and what not. To be honest should I just wait and see? Tomorrow I will be putting three big chunks of driftwood in the tank to provide more cover, would this help?
What if I was to start a comm aro tank? Add another 2 arowanas to the tank to divide the aggression?
Or should I just sell the arowana? This might sound odd but I'd rather keep the oscar, who I have owned for 7 years rather than the arowana, which I owned for 1 year.
Any help on this matter would be good.

if it is agressive to an oscar then it will be agressive tward other aros aswell(in most cases) if it isn't to bad i would wait it out. if the aro dosen't lose intrest in the oscar and you have to choose then you will. i have never owned an asain aro, so i can't give you personal exp on them, but thats been my exp with silvers and jars. with jars expecially if the fish dosen't like a type of fish it will not changce. silvers tend to go through streaks were they don't like some fish and give them all kinds of hell, then only a few days later it is if the target fish didn't exsist.

I'm afraid he's one of the mean ones.

You could try more aros but have you got extra tanks to use as quarantine in case they shred each other? I doubt two more would make much difference, tbh.

Thanks for the input.
Anyone else?

i have got a jardini in a 170 gallon with 2 common plecs and in a 55 gallon 2 baby ocars, so when the oscars are big enough they will go in with the aro. so its fingers crossed, but i think my jar (touching wood) is a nice one cause he's fine with the plecs.

Take it out of the tank and spank it. Then send it to bed with no supper.

Rearranging the tank might help, if not, probably out of luck. Dithers could work too possibly. Anyhow, I had a 90 that was completely overstocked (but had the filtration to match it) and it was odd, if the pot was in a certain spot, no problems, clay pot moved a few inches and it was just a war zone. This wasnt with any arowanas but same idea. Sometimes experimenting works, but I'd almost try to play it safe in this case if you don't have another tank, would rather just keep the oscar around.

Wazup snow! whats the tanks size? is the back painted black? what do you have on the sides of the tank, like on the outside? what are the tankmates? what does the aro eat? answer these questions so i can help...
