I don't know if my boy had an official coloring type because he had multiple layers of irridescence and some colors were more visible than others depending on the lighting. That being said, I would say he was tri-colored or multi-colored.
forgive me for bothering you but do you know the colouring type of the betta in your photo? my Myr is a similar type but with the blue and pink switched. I have been trying to figure out the name for his colouring. thanks for your time!
