I have a 4 month old 48 gallon reef tank. A week ago, I added a yellow striped maroon clown. Right away my flame angel went after it relentlessly. The maroon clown now has torn fins and is relegated to the top of the tank. Anytime it drifts down towards the bottom of the tank, it is attacked. I've added new live rock in an attempt to establish new territories but to no success. I'm worried that my clown will croak if the attacks continue and was thinking of removing the flame for a couple of days before re-introducing it back into the tank. Hopefully by then the clown would have had a chance to settle and establish it's own territory. Will this work or does someone out there have a better idea?
