Damsel
Fiji Blue Devil Damsel
Chrysiptera taupou
A brilliant electric-blue damsel (the male washed with yellow along the belly and tail) that is almost indestructibly hardy and cheap — but genuinely, intensely aggressive. It defends a rock territory with real ferocity and should be kept one per tank unless a proven pair, and only alongside fish that can defend themselves. Reef- and invert-safe, so it will not touch corals or shrimp, but it is a poor citizen in a peaceful community and is best added last.
Keep just one per tank — two will fight.
