So recently I lost my female clown due to my tang flipping out in the night and stabbing her. A little later I purchased a new juvi B/W clown and H. Mag. anemone for the two of them. Ever since the female died, the male has been amazingly aggressive towards anything coming into the tank. I don't think that putting an anemone in the tank helped in the least since they used to just host the PH. Is this common? Will he ever calm down? He is only aggressive towards things coming into and going out of the tank, not other fish or inverts. Mean as a maroon, I'm just lucky he can't make me bleed... yet...
