I don't know if I would say that change is necessary, but it sure seems to get more consistent results, both with follicular development in females, as well as males courting and breeding. A 5 degree drop in ambient temps (not basking spot temp) both night and day, along with a shorter light cycle usually does the trick for us quite nicely. Your male sounds like he is doing his job pretty well which is a good sign, but that doesn't mean your females are developing. Have you tried palpating them? If not, I would suggest learning how. Palpating is one of the best tools in determining if a pairing is successful or not, as well as helping you plan for ovulation. I hope to see you post some pastel baby pics in the coming months!!
