Small and hard to photograph but I was lucky enough to get a portrait shot of a Chrysiptera parasema, also known as yellowtail damselfish. In the wild, male C. parasema have their own territories, located near a nesting site. Each territory contains eggs from previous females. The females will swim around inspecting each male and its territory before choosing one based on its size and the number of eggs in its territory. As a part of the evaluation, the female will display a light ring around her eyes, and the male will respond with its own displays. The next day, the female will spawn with the chosen male. An individual male can have up to 10,000 eggs from different females. Males often abandon their territories to claim territories with more eggs, as this makes them appear more favorable to the females. The eggs hatch after up to 4 days, depending on temperature, and the male is responsible for guarding and caring for the eggs. The subsequent larval stage can take 10 to 50 days.
