I have a well established mixed reef going - a 180 bow front. I have several tangs in there, as well as an excellent specimen of the the red sea sailfin, I have a fellow reefer that is breaking down his tank, and has one he would like to go to a good home - mine... the question is; can you tell a male from female? should i put him in and "see what happens" (bad idea, i think). any help would be appreciated.
