Description
The Blueline Demoiselle, a color variant of the Azure Damselfish, is a small and hardy saltwater fish known for its vibrant yellow body and a striking blue stripe running along its back and through its eye. This active species is a popular choice for reef aquariums due to its attractive coloration and resilience. While generally peaceful with larger tankmates, it can exhibit territorial behavior towards conspecifics or similar-sized fish.
