Chrysiptera parasema

👉Chrysiptera parasema, also known as yellowtail damselfish, yellowtail blue damsel, goldtail demoiselle, and other variations, is a popular saltwater aquarium fish from the Indo-Pacific.

👉It was described by Fowler in 1918.

C. parasema is blue with a distinctive yellow caudal fin (tail fin).

👉The yellow coloring may extend up to the back of the anal and dorsal fins, especially in species from Papua New Guinea.

👉These fish may also have yellow pelvic or pectoral fins.

👉However, yellow is never found on the backs or bellies of Yellowtail Blue damsels.

👉A yellow belly likely indicates that the fish is actually an Azure demoiselle, whereas yellow areas on the nose or chin may indicate that it is a Blue Devil damsel.

👉Yellowtail Blue damsels prefer densely populated coral groupings in sheltered lagoons and inshore reefs, and generally remain between at a depth of between 3–52 feet (1–16 m).

👉Chrysiptera parasema contain chromatophores and can change color in response to external stimuli.

👉 When stressed, they can turn darker to conserve energy.

👉Adults are usually found alone or in pairs, while juveniles are more likely to remain in small groups.

👉C. parasema are omnivores.

👉In nature, they feed on plankton, algae, and small benthic crustaceans.
