Yep! That is what makes me think it is a cross between the 2. However, Amarillo don't always show yellow or orange coloration in their composite either. Some do some don't. Depends on the population at its collection point. At 5 inches whether it is a cross or not, it will probably be more than your Sajica pair can handle aggression wise, as they are not nearly as aggressive as a Con or Amarillo. If it is somehow a cross you may have a real nightmare aggression wise. Who knows it may even be stunted Amarillo. As I said, it will be interesting to see what happens. At 5 inches, it would be a pretty mature Convict and fairly mature Amarillo as well. Good luck vern, I am very curious as to how this will go. Try to keep us updated.
