I don't think they are related. I bought them at different times from a man with a breeding colony of Pearls. Unfortunately, the colony was sold off and we haven't heard anything about them since...
Wish I knew breeding age for this species of Pearl. Just gonna have to wait and see...on a side note, the Mantilla sp is getting her disk chewed up by my blackie male. Hope to see something there.
Utah is also in the Midwest as well. Heck ill say whatever to have an opportunity at a pearl pair. . They are on my top wanted list. Yours look really good.
