Temperament
Description
A stocky Caribbean damsel that starts life as a velvety dark blue juvenile speckled with electric blue 'jewel' spots, maturing into a drab brown-olive fish with a bright yellow tail. It is hardy and easy to feed but becomes genuinely aggressive and territorial as it grows, bullying smaller tankmates and defending a chosen cave or rock pile. Give it a large, rock-heavy tank of 50+ gallons with robust companions added before it, and expect it to nip at some soft corals and gorgonians while grazing algae.
