your skimmer may go a crazy that is normal, it will take the melifix out of the water as melifix is a plant extract it is a natural product. May not exist in the ocean but there are similar plant extracts taht are out in the ocean. give it a dose every 3 days till they stop fighting. the only othr alternitive is to interduce anouther clown that is much larger than the other 2 then peace should come forth prity quickly. The largest is always the dominate and the other 2 will fall in line they will then both stay smaller. but you would have to do it like right now before one starts growning and becoming dominate. They can be prity mean when I put my hand in my tank to clean the glass my female vites and some times takes a little chunk out of my arm or the back of my hand. I just shoo her away after a while she understands to leave me alone. I think she is getting the idear as she now watches my hand when I feed her Nem and just kind of treads water out of the way.
