I just bought a Clarkii and it only been in my reef tank for 1 week. The fish is about 2 inches long and it is acting too aggressive towards other fishes in the tank, especially to the coral beauty. I tried this morning when the lights were off but no luck. Does anyone have any experience with this kind of behaviour with this type of fish? What I am really looking for is a way to get this fish out and put it in the sump.
