Heniochus Bannerfish

Heniochus acuminatus  

Reef Safe with Caution

The Heniochus Bannerfish, also known as the Longfin Bannerfish or Pennant Coralfish, is a visually striking marine fish recognized for its elongated dorsal fin, which resembles a flowing banner. It features a white body with bold black vertical stripes and bright yellow accents on its tail and pectoral fins, giving it a dramatic and elegant appearance. This makes the Heniochus Bannerfish a popular choice for marine aquariums, particularly for those looking to add a touch of elegance to their setup. While generally hardy, Heniochus acuminatus is considered reef safe with caution, as it may occasionally nip at soft corals, anemones, and small invertebrates, especially if not well-fed. To minimize such behavior, it’s important to provide a varied diet and ample live rock for grazing. The Heniochus Bannerfish thrives in well-established tanks with plenty of swimming space and stable water conditions, making it a beautiful and manageable choice for aquarists with some experience. It is also known to be a social species, often seen in pairs or small groups, which can help them feel more secure and display their natural behaviors in an aquarium setting.
