The Blue Reef Chromis (Chromis cyaneus)) are the coolest fish I’ve seen during spawning. I’m assuming it’s the female that changes color, but I guess it could be the male. (Comments please). She instantly turns bright blue (almost white) on the bottom side of her body and paces the tank feverishly. She combs the sand and coral. Her body color can turn back to dark blue instantly and then back to light blue again.
It’s impressive.
