Alright guys and gals, I have 2 female P walhbergii and one male. One of the females and the male are about 3 weeks old now and for some odd reason they just aren't mating. I place the male behind here about 4 inches away (I have varied distances) and he does nothing but snap at her. He won't even go towards her. I am positive that it is a male and a female. I just can't figure out what is going on or what I am doing wrong. Any helpful hints on these P walhbergii?
