Someone correct me if I'm wrong here, but I believe Salamander means the fish has distinct white bands at the ends of it's fins, and two colors on the body, usually differentiating the head from the torso.
I took some new pics not sure if this helps. I was asking because I have done a lot of reading especially on betty splendens website and she says that many fish get mistaken as MG but are in reality are not :( I am confused and have not found any clear standard on the MG :(
Not sure what it all means yet but I am working on it. My best guess is that mine is just a bi color and not a MG since I don't have one of the fish from that original line. He is still a cutie regardless
