I talked to one farm that actually crossed them. He showed me parent pics from the pond and the fry. He took known breeding male silvers and known breeding female blacks, or flipped I don't recall it was a couple years ago. Only had males of one and females of the other and got fry. He told me everyone said it couldn't be done and wouldn't buy them for what they were. So he called them something different. I don't recall the name he changed it to. He has asked me to keep him anonymous.
I have a black aro it had a lot of blue not in the body but in the top and bottom find. There often called blue aro.I have not seen it yet. I'll get a picture as soon as I get one!
That's what I was referring to, a natural blue tint when smaller. To bad I was hoping to see something new.
You chance of a blue?
