Chrysiptera parasema, commonly known as the Yellow-tailed Damselfish, is a small, vibrant marine fish belonging to the family Pomacentridae. It is highly sought after in the aquarium trade due to its striking coloration and relatively peaceful demeanor compared to many other damselfish species. This species is characterized by its brilliant blue body contrasting sharply with a bright yellow caudal fin and posterior dorsal and anal fins. They are typically found in coral reefs, inhabiting crevices and branching corals for shelter.

Coloration
Look for the unmistakable electric blue body with a sharply contrasting bright yellow caudal fin and posterior dorsal/anal fins. This bicolor pattern is highly characteristic.
Size and Shape
Small, laterally compressed body, typically under 3 inches. This helps distinguish it from larger damselfish species.
Behavior
Often seen darting in and out of coral branches or rockwork, exhibiting territorial behavior towards conspecifics or other small fish.
Habitat
- Tipo di acqua
- saltwater
- Profondità
- Typically found at depths of 1-30 meters (3-100 feet), most commonly in shallower reef areas.
- Ambiente
- Coral reefs, particularly in areas with abundant branching corals (e.g., Acropora) and rocky crevices, which provide shelter and foraging grounds. They are often observed in lagoons and outer reef slopes.
- Areale geografico
- Western Pacific Ocean, including Indonesia, Papua New Guinea, Solomon Islands, Vanuatu, and the Great Barrier Reef (Australia).

Aquarium Popularityinteresting
One of the most popular damselfish species in the marine aquarium hobby due to its vibrant colors and relatively manageable temperament.
Territorial but Tolerantbehavior
While territorial, especially towards conspecifics, Chrysiptera parasema is generally less aggressive than many other damselfish species, making it a better candidate for community tanks.
Reef Dwellerbehavior
Strongly associated with coral reefs, relying on the complex structure of corals for shelter from predators and for foraging opportunities.
Dietary Flexibilitybehavior
As an omnivore, its diet in the wild consists of zooplankton, benthic invertebrates, and various algae, showcasing its adaptability in foraging.

Azure Damselfish
Chrysiptera hemicyanea
The Azure Damselfish has a blue body with a yellow belly and anal fin, but its caudal fin is typically blue, not yellow. The yellow coloration on C. hemicyanea is more ventral, whereas in C. parasema, it is primarily caudal and posterior dorsal/anal.
Springer's Damselfish
Chrysiptera springeri
Springer's Damselfish is entirely blue with no yellow coloration. It is often confused with C. parasema in terms of body shape and size, but the lack of yellow is a clear differentiator.
Talbot's Damselfish
Chrysiptera talboti
Talbot's Damselfish has a purplish-blue body with a yellow tail, but it also features a distinct black spot at the base of the pectoral fin, which is absent in C. parasema. The blue coloration is also often deeper purple.
