Cirrhilabrus aquamarinus, also known as the Koi Dwarf Parrot Wrasse, blue green fairy wrasse, is a beautiful and colourful saltwater fish that is popular among reef keepers. Here are some general guidelines on how to keep Cirrhilabrus aquamarinus:

  1. Aquarium size: Blue green fairy wrasses need a minimum tank size of 50 gallons. They are active swimmers and need plenty of swimming space.
  2. Water conditions: These fish require stable water parameters with a temperature range of 72-78 degrees Fahrenheit, pH of 8.1-8.4, and salinity level of 1.020-1.025.
  3. Filtration: A high-quality filtration system is essential to maintain good water quality. A protein skimmer, power filter, and live rock are recommended for a 50-gallon tank.
  4. Lighting: Blue green fairy wrasses require moderate to high lighting levels to maintain their vibrant colours. LED lighting with a spectrum that mimics natural sunlight is ideal.
  5. Decorations: Provide plenty of hiding spots and caves for your fish to explore. They will also appreciate the presence of live rock and coral, which can provide additional hiding spots and natural grazing areas.
  6. Feeding: Blue green fairy wrasses are omnivores and require a varied diet that includes high-quality dry and frozen foods, as well as live foods such as brine shrimp, Mysis shrimp, and copepods.
  7. Compatibility: These fish are generally peaceful and can be kept with other peaceful fish and invertebrates. However, they should not be kept with aggressive fish or fish that are significantly larger than them. It is best to keep only one male in a tank, with several females to form a harem.
