Clown Knife Behaviour

[miss__kp]

I've recently picked up an 8cm silver clown knife that is currently living in a 3 footer with a paroon shark thats slightly smaller.

The knife is getting a bit nippy when its hungry, after they've been fed they stay on opposite sides of the tank. It does chase the paroon a little, but seems to give up on the idea fairly fast.

I'm hoping to put the knife in my 350 gal that has an arowana in it. Just wondering if they are fin nippers by nature and will this be a problem in the future?

Thanks!

Usually they don't mind other fish. When you change the tank and give the CK some more room, it may change it's disposition.
