Chrysiptera parasema (Fowler, 1918)
Like all damselflies, this one is quite hardy and not very disease prone or finicky. They show strong territorial behavior, attacking even larger newcomers to the tank. They quickly take up any food. In the wild they live in small groups usually near or in Acropora stony corals where they find shelter from large fish.
Yellowtail demoiselles prefer densely populated coral groups in sheltered lagoons and coastal reefs, and generally prefer depths between 1 and 16 m in the sea.
In the sea, males have their own territories located near a spawning site. Each territory contains eggs from previous females. Females swim around and inspect each male and its territory before selecting one based on its size and the number of eggs in. As part of the evaluation, the female shows a bright ring around her eyes, and the male responds. The next day, the female will spawn with the selected male. A single male can nurse up to 10,000 eggs from different females. Males often leave their territories to claim areas with more eggs, as this makes them appear more favorable to females.
The male is responsible for guarding and caring for the spawn. Hatching occurs in darkness depending on water temperature after up to 4 days, The subsequent larval stage can last from 10 to 50 days.
Yellowtail demoiselles have chromatophores in their tissues, allowing them to change color (become lighter or darker) in response to external stimuli.
Adults are usually found singly, while juvenile su their protection tends to remain in small groups.
Chrysiptera parasema are omnivores. In the wild they feed on plankton, algae and small benthic crustaceans. In the aquarium they are unproblematic food-wise and also eat frozen and dry food.
