Re: sexing. Are you talking about the tail or the ventral fins. A couple of them are getting a nice bluish sheen on these. I've never had fish like these guys before. They remind me of some of the puppets on the Muppet show. Are you really serious about their being so prolific? Oh my God. We already have enough problems with the Kribs. Are they as bad as those? Also, since they are all in one tank, will I have to spread them out when they form pairs? John Wubbolt wrote that they will get pretty feisty once they form pairs. How on earth do you have a hundred of them? How many tanks do you have with these fish in them? Gabriella p.s. all the blood has gone out of my head and into my toes. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
