Yellowtail Blue Chromis (Chrysiptera parasema)<\/strong><\/h2>\n

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

The Yellowtail Blue Chromis, sometimes called the Yellowtail Damselfish<\/strong>, is a small but brilliantly coloured marine fish. Its body is an intense electric blue, contrasted by a bright yellow tail fin. Reaching only 6\u20137 cm (2.5\u20133 inches)<\/strong>, this hardy and vibrant fish is a long-standing favourite in the aquarium hobby. Despite being one of the more peaceful damselfish<\/strong>, they can still show territorial behaviour, especially in confined spaces.<\/p>\n

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

Native to the Western Pacific<\/strong>, especially around the Philippines, Indonesia, and the Solomon Islands. Found in lagoons, sheltered reefs, and coral rubble zones, often close to protective crevices.<\/p>\n

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

An omnivore<\/strong> with a big appetite. In aquariums they adapt readily to most foods:<\/p>\n

    \n
  • \n

    High-quality marine flakes and pellets (staple diet)<\/p>\n<\/li>\n

  • \n

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

  • \n

    Finely chopped seafood (shrimp, clam, squid)<\/p>\n<\/li>\n

  • \n

    Spirulina and algae-based foods<\/p>\n<\/li>\n<\/ul>\n

    Feed 2\u20133 small meals per day<\/strong> for best colour and health.<\/p>\n

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

    The Yellowtail Blue Chromis is one of the milder damselfish<\/strong>, but still semi-territorial. Good tank mates include:<\/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

      Dwarf angelfish<\/p>\n<\/li>\n<\/ul>\n

      Avoid housing with very shy fish that may be stressed by their activity, or with very aggressive species that could bully them.<\/p>\n

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

      Semi-aggressive.<\/strong> While considered peaceful by damselfish standards, they will defend a small territory, particularly in smaller aquariums. Best kept singly, in a bonded pair, or in larger groups (6+ in a spacious tank)<\/strong> to disperse aggression.<\/p>\n

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

      Beginner-friendly.<\/strong> Very hardy, colourful, and easy to feed, making them an excellent choice for new marine keepers and reef aquariums.<\/p>\n

      Water Parameters<\/strong><\/h3>\n
        \n
      • \n

        Temperature:<\/strong> 24\u201328\u00b0C (75\u201382\u00b0F)<\/p>\n<\/li>\n

      • \n

        pH:<\/strong> 8.1\u20138.4<\/p>\n<\/li>\n

      • \n

        Salinity:<\/strong> 1.020\u20131.025 SG<\/p>\n<\/li>\n

      • \n

        Hardness (dKH):<\/strong> 8\u201312<\/p>\n<\/li>\n

      • \n

        Tank Size:<\/strong> Minimum 30 gallons (115L)<\/strong> for a single or pair; larger if keeping a group<\/p>\n<\/li>\n<\/ul>\n

        Provide rockwork with caves and crevices so they can establish territories.<\/p>\n

        Reef Compatibility<\/strong><\/h3>\n

        Reef safe.<\/strong> They do not harm corals or invertebrates, and their bright colour contrasts beautifully in reef setups.<\/p>\n","protected":false},"excerpt":{"rendered":"
