Good hearing from you, June! You said: "My experience was that pH infulences gender ratio in live bearers. At first I thought it was water temp but changing that made little if any difference but pH did." Now, please tell us, was it high pH or low pH that produced more females? I'm really concerned about my lack of female Endler's. I don't want to lose my entire colony because they're producing only male offspring. Growing old is inevitable; growing up is optional. _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
