actually she herself probally smells receptive if she was mating with the tang. He is just trying to mate her. If she is going to be gravid and laying and you have a set-up why not just leave her in there or with the tang.
:I have a female that i had in with my tang for a day then when i went to put her back in with the albino group the male attacked her so i put her back with my tang male after i rubbed her down with luke warm water to get the sceant of anf the tang male bit her still so i tried rubbeing her down with my sceant that didnt work either so i set her up a temp home in a 20H...how long should i leave her in her before putting her back in with the albino group????
