Knife and Jardini Aro

[95socalstang]

I currently have a GCK with my aro and the CK seems to be attacking the aros fins at night. I don't want to get rid of the CK but he isn't leaving me much choice. I added some tinfoil barbs to hopefully give him another outlet for his aggression. Is there anything else I can do? He currently will only eat live food...

keep an eye on him
my royal ck killed my aro in his sleep
beat the hell out of him
they were both 10" fish

As of right now I have only actually seen the CK go after the aro once. I rearranged the tank due to the CK getting WAY too protective over part of the tank. I took away a bell that basically allowed the CK to strike out and hide without the aro being able to do anything about it. Are different CK's just more aggresive then others? I had a regular CK that and another aro in the past and never had issues. They both grew to around 20 inches.
