Interesting... Now I will probably hijack my own thread, but I have to ask. If what you say is true (which I have no reason to contradict you) then why are the males so aggressive? I have just believed what people have said (that they are guarding eggs against gobies and such) and went along with it because it made sense. Now I am going to have to research it. But I'm curious as to what others think or know about why the male are so aggressive in certain areas, if not protecting eggs.
