Do you have photos of the animals?
Breeding Kenyans is pretty easy, many people do not cool them down and are successful. I personally cool mine a little. From December to February I give them a warm spot of ~85-87F, with a cool spot about 72-75F verses the 95F (cool spot of about 78-83F) in the summer.
I have bred Kenyans by keeping them together year round (both 1.1 and 1.2 combinations), and by introducing them in the spring (March-June).
Your male is definitely ready….175g is a big male; most males breed at 1-1.5 years @ 70g+.
The one female is on the smaller side (280g), but the other female should go. (I have not been keeping track of the starting weight of females but will in the future). I usually do not breed my females until 3 years old. Most my breeder females range from 450g-600g.
Also, during breeding season males tend to go off feed. Has your male done this? This is usually a sign he is interested in breeding. I have had males stop feeding anywhere from 2-7 months, so do not be surprised if he refuses food. I would offer him meals about every 3 weeks just incase, and eventually he will feed again.
Feel free to e-mail me with any questions…
