yes, at 6" it's almost transparent, 12" should start showing the background base.color, 15-16" it really white starts to pop. That's when the red really pops as well. I would be concerned about the head but if you purchased it for the heart on the head in hopes of it staying dark then it may work out for you. Hard to say at this point but it may always stay dark and not whiten up. nice fish, I think you will really enjoy watching this one grow.
