It could very well be red dragon but its definitely got some fader Gene's in it if it changed colors so drastically. I've got 2 female FH's that are both part fader. One kept almost all it's original color, only has one pink spot on the anal fin. The other ended up almost all pink with lil flecks of black in the edges of her fins.
Fader's can vary extremely from one another. They can also change colors over time as they mature as well, but they do all start with normal breed coloration/pattern when born. I got to say tho yours is coming along nicely so far, already showing a bit of orange and gold. As it gets older the colors will begin to pop out more and more.
