Neon Velvet Damsel (Neoglyphidodon oxyodon)
The Neon Velvet Damsel, Neoglyphidodon oxyodon, is a striking Western Pacific damselfish admired for its electric blue juvenile colouration, dark velvet body tones and bold reef presence. Also known as the Bluestreak Damselfish or Blue Velvet Damsel, this species is hardy and eye-catching, but it should be chosen with care as it becomes increasingly territorial as it matures. In nature, it inhabits very shallow coral reef flats and lagoon areas, often close to branching Acropora coral heads where it can shelter quickly.

The Neon Velvet Damsel is a vibrant addition to my reef tank. The blue coloration is stunning, especially in the juvenile stage. I’ve noticed it becomes more territorial after a few months, so I made sure to provide plenty of coral structures for hiding. It’s active and adds a lot of visual interest.

I bought this damselfish for a new reef setup. It’s very colorful and stays near the Acropora coral, which is perfect. After a few weeks, it started showing signs of aggression toward smaller fish, so I adjusted the tank layout to give it more space.

The fish arrived healthy and quickly adapted to the tank. Its blue streaks are vivid and it’s very active during the day. I keep it in a 120-liter reef tank with plenty of live rock and branching corals. It’s a great visual focal point.
