🐠 Black & Gold Chromis (Neoglyphidodon nigroris)
A Bright Yellow Juvenile With Two Black Bars • A Damselfish, Not a True Chromis, Despite the Name • A Bold Adult Temperament Worth Planning For
 
📋 The Black & Gold Chromis, also known as the Gold Nugget Damselfish or Behn's Damselfish, is sold as an attractive juvenile with a bright yellow body crossed by two black bars.
It comes from reef environments across the Indo-Pacific. A naming note worth knowing: this species is technically a damselfish rather than a true member of the Chromis genus, despite the common name. Every Black & Gold Chromis we ship is feeding well.
As this species matures, it undergoes a real transformation, becoming distinctly more assertive and territorial, often losing much of the attractive golden juvenile colouration in the process and developing a duller, darker adult appearance. The charming juvenile you bring home is not a preview of the adult temperament or looks you'll end up with in a year or two, so it's worth planning for the adult from the start. It's best kept singly, in a spacious tank with ample rockwork and hiding places, and thoughtful tankmate selection matters more with this species than with most beginner damsels. It remains a hardy, easy-care fish for keepers who go in with realistic expectations. It reaches up to 13cm, so a 115L tank suits it well.
