Dragon scaling is thick and provides a quality of iridescence (refractence, actually) that most Betta do not have, even iridescent ones..
There is also a unique scale distribution as shown in those photos. Thanks, Setsuna.
Purists insist that a true "dragon" has white scales only. Some include light blue. The rest are referred to as "coppers." My opinion is that any thick scale fish that has those characteristics should be called a"dragon."
I'm often wrong. ;-}
The difference between a DeT and a VT are not a matter of votes or opinions, but quantifiable characteristics. Check the IBC website or BettySplendens.
