I bought him as proven fertile. But I have not found a female good enough for him yet. I do have a SB zz female that he is paired up with, and gets along with, but she has not dropped a tube yet. And the last female I tried, beat the crap out of him . So I going to give him and the SB a lil time, then I am going to start looking for a good fertile female for him. I have 2 kamfafemales that I feel are a ll too small for him, one is 4 " not that pretty, but is fertile-laid 2 x already. May try her next.
