Overview
A blushing angelfish is largely clear silver white with a pink patch behind each eye where the gill cover lets the gills show through. The pink is strongest in young fish and often fades as the gill plate turns opaque with age, so an adult sold as Blushing may no longer blush. Adults also pick up scattered silvery guanine patches on the body, which is normal for the form rather than a flaw.
In the wild
Blushing is a double dose of the stripeless gene, a hobby mutation with no wild equivalent. Stripeless shares a locus with zebra, so a blushing fish can never also be a zebra. When and where the stripeless mutation first appeared is not recorded in the hobby literature, which makes blushing a line of uncertain origin.
Good to know
Stripeless shows intermediate inheritance: one dose gives the ghost, which keeps incomplete bars, and two doses (S/S) give the blushing fish. The double dose leaves the gill cover translucent, so the red of freshly oxygenated blood in the gills shows through as pink. That same transparency is what lets koi and the other stripeless based forms show the color stored underneath.
Did you know
The blush is not pigment at all. It is blood in the gills seen through a gill cover that stays translucent, which is why the pink retreats as the fish matures and the plate turns opaque.
