bettalover: "true blue" dragon is only something I used/said because irid colored dragons doesn't conform to the original goal of light colored body. For some reason irid colors would not "give in" to the light color in dragon scales. But
THEY ARE ALL dragon scales. And they will breed true.
IMO the common blue dragons are amazing because sometimes they look blue and sometimes they look turquoise. So you get 2 colors in 1 betta.
As dragons are becoming more common and are being over mixed bred - IMO they look more like regular blue/turquoise. So I'm not sure if the above is a dragon or not. His scales look regular. He is masked, though not full. And as far as I know, masking occurs easier in dragon breeding - though it is said that coppers may cause masking.
Try not to worry about "true blue" dragon - dragons are dragons and will breed true. Sorry I caused all this confusion. I never thought my statement would cause such confusion.
