Allen’s Damsel is a striking yet often underrated member of the Chrysiptera genus, known for its vibrant coloration and compact, athletic body shape. Adults typically display a rich electric blue to bluish-purple body accented by bright yellow or gold on the face, dorsal area, or tail region, depending on lighting and mood. Like many damsels, their coloration intensifies under good water quality and proper diet. They are relatively small, usually reaching about 2.5–3 inches, making them suitable for a wide range of marine aquariums. Allen’s Damsels are alert, fast swimmers and spend much of their time darting in and out of rockwork, defending a chosen territory.
