The Goldtail Half Blue Damsel, Chrysiptera cf parasema, also known as the GoldTail Blue Damsel, features a bright blue body with striking yellow gold coloring on the bottom fins and rear end of the body. They are very similar looking to the Yellowtail blue damsel but the yellow runs further up their body and along the ventral fins giving them more contrast. They are a prime community reef fish that live best in small groups of at least three or more, or else they can become territorial. The Goldtail Blue Damsel is very hardy and eats almost anything contributing to its lifespan of up to five years. This Damsel is a versatile fish that will thrive in almost any home aquarium.
