Chrysiptera cyanea-The orangetail damselfish or sapphire damselfish are brilliantly blue. They are incredibly hardy addition to any small or medium aquarium. Males develop a distinct vibrant orange tail in small groups and coloration develops further when they are ready for spawning and courting. These damselfish can become a bit aggressive if constrained for space but stay docile if kept singly with a good amount of rock work. Feeding on C1, C2, Hikari Mysis, PE Calanus
