I put my Albino male Carpet on my black Irian Jaya this past season. She developed a bad RI while gravid and I had to treat her with Baytril a few times during this and she also did not eat at all during this time.
She eventually dropped her eggs about 2 weeks later than the year before and of the 19 eggs, only 3 were viable. I incubated them and hatched 2 females and 1 male.
Here are a few pics of the Hets, showing the nice red you always see in baby Darwins.
The one female is darker than the other 2 but she has some shedding stuck to her head so skipped taking pics of her.
