Your Guide to Buying and Adding a Green Chromis to Your Tank

The Green Chromis, Chromis viridis, is a popular and hardy choice for both beginner and advanced aquarists. Its calming greenish-blue hue and playful, schooling behaviour make it a favourite in many saltwater aquarium setups.

Choosing the Right Green Chromis

Selecting a healthy specimen:

  • Look for lively fish with bright colours and an absence of any physical injuries.
  • Check for any signs of distress or illness like erratic swimming, spots, or faded coloration.

Physical Appearance

Describing the Green Chromis:

  • Has a shimmering green to blue-green colour.
  • Slim, oval-shaped body.
  • Can grow up to 4 inches in length.

Compatibility with Other Fish

Ensuring peaceful coexistence:

  • Green Chromis are generally peaceful, especially when kept in groups.
  • Ideal for community tanks with similarly tempered fish.
  • While they school, avoid overcrowded conditions.

Reef Safe

Considering the coral environment:

  • Fully reef-safe.
  • They won’t harm corals or invertebrates.

Suitable Tank Size

Space considerations:

  • Minimum of 100 litres for a small group.
  • The more space they have, the better they'll display their schooling behaviour.

Water Conditions

Maintaining a healthy environment:

  • Temperature: 22-26°C
  • pH levels: 8.1-8.4.
  • Specific gravity: 1.020-1.025.
  • Regular water checks to maintain zero ammonia and nitrites, and low nitrates.

Preparing Your Tank

Setting up an ideal habitat:

  • Plenty of open space for swimming.
  • Some hiding spots with rock formations or coral structures for shelter.

Monitoring Behaviour

Understanding their behaviour:

  • Naturally schooling fish that swim in the middle to upper areas of the tank.
  • Watch for signs of bullying or stress, especially if one is singled out from the group.

Feeding Schedule

Nourishing the Green Chromis:

  • Omnivorous diet, but primarily feed on plankton in the wild.
  • Offer a variety of foods including marine flakes, micro-pellet food, brine shrimp, and finely chopped seafood.
  • Feed 1-2 times daily in small amounts.

Adding Green Chromis to your aquarium brings a splash of vibrant colour and dynamic movement, especially when they move together as a group. Their peaceful nature makes them an excellent choice for a harmonious marine environment. Proper care and monitoring will ensure they thrive and bring joy to your aquatic display.
