I introduced a male to my tank last night and after he and the female came face to face a major fight began. My female is bigger than the male and she put it on him to the point that I had to break them up a few times and when it just persisted had to remove him to the refugium. Anyone have any thoughts.. he actually looked like he had two spots on his tail that were missing fin. I am wondering if perhaps the female that I assumed I had may in fact be a male that somehow had a damage dorsil fin... wonder if that is possible that something ate it or somehow it was damaged and that she is actually a male. Does anyone have any pics of a female extended that I can look at to see if there are any other characteristics that I may see. Any advice would be greatly appreciated.
