Bluefin Damselfish: The Transforming & Aggressive Staple
The Bluefin Damselfish (Neoglyphidodon melas), often called the Blue-streak Damselfish, is a well-known and hardy species with a dramatic transformation from its juvenile to its adult form. As a juvenile, this damselfish is highly prized for its striking jet-black body with a vibrant, electric-blue stripe running along its back. It is important to note that as this fish matures, it loses its brilliant blue stripe and becomes a solid black or dark gray, while also becoming highly aggressive and territorial. For this reason, it is best suited for an aquarium with more assertive or larger tank mates. It is completely reef-safe and will not harm corals or invertebrates.
Why the Bluefin Damselfish is a Great Choice:
- Hardy & Durable: This is a very robust species that is easy to care for and a great choice for beginner aquarists.
- Striking Juvenile Coloration: Its iconic blue pattern makes it a popular choice.
- Completely Reef-Safe: It will not harm corals, clams, or most other invertebrates.
- Adds Energy to the Tank: It is a very active swimmer that adds a lot of energy and movement as it explores rockwork and guards its territory.
