My Banggai's that i had did the "dance" for 2 days in a row about a month ago, and since then...nothing. In my 80gal i have 1 really big yellow tang who gives them a scare about once a day or so...nothing too big.. I just recently put in 50pounds of lr so i am not really expecting them to do anything in the next week or so, but is there anything i can do to get them to dance again? is it a possibility that one of them is sterile, or what they just not dance if that was the case? Do you think it could be the yellow tang that is bothering them and keeping them from breeding? ANy thoughts would be much appreciated...Thanks for your time
