Blueline demoiselle

The Blueline or Yellowfin Demoiselle, scientifically named Chrysiptera caeruleolineata, is a small marine fish characterized by its vibrant blue body with distinct yellow fins. It originates from the Indo-Pacific region, including areas such as Indonesia and the Solomon Islands. This species typically exhibits a sleek, streamlined appearance. Despite its striking appearance, it is not among the most well-known species within the aquarium hobby, partly due to its specific care requirements and relatively less prevalence in comparison to other marine ornamentals.
