My leos (6) have done the deed but as of yet no luck, I just put the males back in the 2k tank for some freeking & we'll see if the job gets done this time. It is a very delicate balance with this many rays, one agro male sturrs all the other males up soo much that i can only have them in the tank for a week or so. I did get my hybrid henlei/motoro to give birth twice & even have a couple batman rays.. believe it or not my smallest motoro had 14 babies last time!!
