Chromis viridis, commonly known as the Green Chromis, is a small, schooling damselfish renowned for its vibrant iridescent blue-green coloration. It is a highly abundant species found throughout the Indo-Pacific coral reefs. These fish are planktivorous, feeding primarily on zooplankton in the water column. They are a foundational species in many reef ecosystems, serving as both prey for larger predators and as a significant consumer of plankton, thus influencing nutrient cycling. Their peaceful nature and striking appearance make them a popular choice for marine aquarists.

Coloration
The vibrant, uniform iridescent blue-green color is the primary identifier. Note how the color shifts with light.
Body Shape
Its small, compressed body and deeply forked tail are characteristic.
Schooling Behavior
Often seen in large, active schools hovering above coral formations, which is a strong behavioral indicator.
Size
Adults typically reach a maximum size of 8-10 cm (3-4 inches) total length.

- Hloubka
- Typically found at depths of 1 to 12 meters (3 to 40 feet), occasionally deeper to 20 meters.
- Prostředí
- Coral reefs, particularly in sheltered lagoons and outer reef slopes with abundant branching corals (e.g., Acropora, Pocillopora) which provide shelter. They form large, loose schools above the coral branches.
- Geografické rozšíření
- Widespread throughout the Indo-Pacific, from the Red Sea and East Africa across to the Central Pacific, including the Great Barrier Reef, Southeast Asia, and various Pacific island nations.

Planktivorous Lifestylebehavior
Chromis viridis primarily feeds on zooplankton, playing a crucial role in transferring energy from the planktonic food web to the reef ecosystem.
Social Schoolersbehavior
These fish are highly social and form large, dynamic schools that provide safety in numbers against predators.
Color Changebehavior
While generally blue-green, their coloration can subtly change based on their mood, stress levels, or reproductive state, sometimes appearing more yellowish or duller.

Blue Chromis
Chromis cyanea
Chromis cyanea is found in the Atlantic Ocean and Caribbean Sea, not the Indo-Pacific. It typically has a more intense, uniform blue coloration and a slightly different body shape, often appearing more elongated.
Blackbar Chromis
Chromis retrofasciata
Chromis retrofasciata has a distinct black bar at the base of its caudal fin and a more yellowish body, clearly distinguishing it from the uniformly colored C. viridis.
Barrier Reef Chromis
Chromis atripectoralis
C. atripectoralis is very similar in appearance but can be distinguished by a dark spot at the base of its pectoral fin and often a slightly larger adult size. Genetic analysis is sometimes required for definitive identification in the field.
