Blushing Silver Angelfish
Note photo shows veiltail fish with longer fins than standard.
Blushing Angelfish are homozygous for the stripeless gene. Not only do stripeless fish lack the distinctive vertical bands, their skin is lacking in reflective iridophores. Because of this the red gill colour shows through the translucent oppercula of young fish - hence the name. As they age the gills lose their translucence and random patches of iridophores develop giving the fish a beautiful mother of pearl appearence.
Blushing silvers are not the most popular of angelfish varieties, but combined with gold marble the blushing phenotype has produced one of the most popular of angelfish varieties - the koi angel.
