The **Blueline Angelfish** (Chaetodontoplus septentrionalis) is a stunning marine fish, appearing in the aquarium trade only during specific seasons, making it a rare find for hobbyists. This species adapts well to reef tanks and becomes quite resilient once accustomed to aquarium life.
As juveniles, the **Blueline Angelfish** features a striking yellow stripe behind its eyes, along with the signature blue lines. As they mature, the yellow stripe fades, but the face develops a yellow tint, and the yellow tail remains.
Reaching a maximum size of approximately 8.5 inches, the **Blueline Angelfish** thrives in aquariums of at least 150 gallons. It prefers peaceful tankmates and quickly establishes its place in the social hierarchy.
This omnivorous fish enjoys a diet of meaty frozen foods and benefits from algae-based foods or Nori to maintain its health.
