I got IMG because that's what they were marketed as. I brought them from Harald (working as your middle man) as "Possible IMGs," and I had the patience to grow them out and prove them out.
I produced two visual females and 2 66% het males. I am still working with them and waiting and documenting any color changes. I will be pairing the two Hets I have again this year to see if I can produce a visual male.
Since you have only the one Het female, according to my information, what are you planning to put your het to?
