If you wanna get this forum's peoples attention,next to anything related to oscars, getting an arowana is a good option!
Quite a lot af Oscarfishlovers are frequently found on Arowanafishlover.com as well.
But not posting pics in a thread like this, is just plain rude and it's considered bad ettiquete to leave us waiting for those pics.
what kind of aro is it?
What's the footprint of your current tank?
i know Paul, Marcus and some other arowana owners will tell you the growtrate of their fish, and i think they can match the oscars growthrate, if i'm correct.
Better look for that big @$$ tank real soon.
i'd say get at least a 180, you'll need it to give the arowana some swimming space.
6Foot is not too much for a long fish like that, allthough they can turn very smoothly.
