South Pacific Green Chromis (Chromis viridis)<\/strong><\/h2>\n

Overview<\/strong><\/h3>\n

The South Pacific Green Chromis, also known simply as the Green Chromis<\/strong>, is one of the most popular and widely kept reef fish. It is admired for its shimmering blue-green body, peaceful nature, and active schooling behaviour. Reaching about 8\u201310 cm (3\u20134 inches)<\/strong>, it adds constant motion and colour to community aquariums. When kept in groups, these fish display their natural shoaling behaviour, darting in and out of corals and rockwork.<\/p>\n

Origin<\/strong><\/h3>\n

Native to the Indo-Pacific<\/strong>, including the Great Barrier Reef, Fiji, Maldives, and Micronesia. They are typically found in large shoals hovering above branching corals on reef flats and lagoons, where they feed on plankton.<\/p>\n

Feeding<\/strong><\/h3>\n

The Green Chromis is an omnivorous planktivore<\/strong> and readily adapts to prepared aquarium diets:<\/p>\n

    \n
  • \n

    High-quality marine flakes and micro-pellets<\/p>\n<\/li>\n

  • \n

    Frozen mysis shrimp, cyclops, and enriched brine shrimp<\/p>\n<\/li>\n

  • \n

    Finely chopped seafood for variety<\/p>\n<\/li>\n

  • \n

    Spirulina or algae-based foods to maintain colour and health<\/p>\n<\/li>\n<\/ul>\n

    Feed 2\u20133 small meals per day<\/strong>.<\/p>\n

    Tank Mates<\/strong><\/h3>\n

    Peaceful and reef-safe, they mix well with a wide variety of tank mates:<\/p>\n

      \n
    • \n

      Clownfish<\/p>\n<\/li>\n

    • \n

      Gobies and blennies<\/p>\n<\/li>\n

    • \n

      Wrasses (reef-safe species)<\/p>\n<\/li>\n

    • \n

      Cardinalfish<\/p>\n<\/li>\n

    • \n

      Other peaceful chromis species<\/p>\n<\/li>\n<\/ul>\n

      Avoid aggressive species (triggers, large wrasses, dottybacks) that may harass them.<\/p>\n

      Aggression<\/strong><\/h3>\n

      Peaceful.<\/strong> Best kept in groups of 5 or more<\/strong>, as they display natural shoaling behaviour and aggression is spread across the group. In smaller numbers, dominant individuals may bully weaker ones.<\/p>\n

      Experience Level<\/strong><\/h3>\n

      Beginner-friendly.<\/strong> Hardy, adaptable, and colourful, they are excellent fish for new and experienced marine aquarists alike.<\/p>\n
