As Pat stated, I would talk to Corey Woods. He is the man when it comes to Het Reds. Keep in mind that Het Reds are just that, Het Red Axanthic. They are a codom and some can be very subtle. If you ask me, I think they are one of the codoms that can be the hardest to pick out sometimes. On the flip side, I'm gonna go out on a limb here and say those look like some Het Reds that I have seen. The whole black back thing going on and the squiggly marks also. Keep us posted. I'm curious to see what the final verdict is.
