Clown Knife and arowana together ?

[Lahan]

Can I keep a silver arowana around 7 inches with a Clown Knife around 12 inches. The aro is well fed and is about 2 inches in height.

Other tankmates includes a 7 inch delhezi bichir , 5 inch rainbow wolf fish and a 7 inch Jade gobby currently living peacefully with the aro for more than 4 months in a 650 gallon tank.

I am mostly concerned about the arowana being tail nipped . Can that happen ?

I wouldn't risk it due to size Clown Knifefish have huge mouths.

They will fight most likely. Had them in a 700g as well.

Had that same pair once but the arro was about twice as long as the knife. They didnt have any trouble but your mileage may vary
