I had a Clarkii at one point. Baaad idea. They definitely seem to be very defensive, aggressive, and territorial. I always got nipped at when I was doing anything in the tank. But, the thing I loved about these fish, was how much they loved their anemones. I spent many hours watching her have a blast in her RBTA. Too cool!
But needless to say, after a few months I found her a new home. Way too aggressive for my liking.
I've noticed with my new fish, if I have a turkey baster in the tank, they run and hide. They venture out briefly, but just the slightest movement from the baster and they are gone. You need to find something like that to keep her at bay while your working in the tank.
