The boy in my avatar started out as a very light pastel that appeared white under regular lighting, but as he got older, he developed the red wash which then started to darken. It's now spread so far that almost the entirety of his fins are maroon, and you'd never know he'd ever been a solid color to look at him. And I don't know why, exactly, but I love love love cambodian females, way more than I love cambodian males. I also had a pretty little cellophane female years back. My mother hates them because she thinks it's gross you can sort of see through them. I'm still a little disappointed I didn't snatch up the cellophane half moon male I had my eye on a couple of weeks ago when I had the chance.
