Green Chromis is a type of damselfish having shiny green and light blue color.
Sometimes, it’s called as Blue-green Chromis, but this might also refer to its close relative, Blue Puller (Chromis caerulea).
Adult Green Chromis live in big groups above branching Acropora corals found in protected areas like underwater reef flats and lagoons.
Young ones stick close to individual coral heads. This fish mainly eats phytoplankton, is active during the day, and safe for coral reefs.
Green Chromis Interesting Facts
- Green Chromis are shiny green and light blue damselfish that can grow up to 3.9 inches (10.0 centimeters) in length.
- These fish live in groups above branching corals found in protected underwater reef flats and lagoons.
- During breeding, males create nests for multiple females to lay eggs, which hatch within 2 to 3 days.
- Green Chromis are found in the Indo-Pacific region, living near reefs at depths of 1 to 20 meters.
Green Chromis Habitat
Green Chromis is found in the Indo-Pacific region.
Its habitat range stretches from Africa’s east coast to the Line Islands and Tuamotus, as well as north to Japan’s Ryukyu Islands and south to Australia’s Great Barrier Reef and New Caledonia.
It lives in marine environments near reefs, doesn’t migrate, and is found at depths of 1 to 20 meters.
This fish thrives in subtropical climates between latitudes 35°N to 35°S.
Green Chromis Physical Characteristics
Size: 3.9 inches (10.0 centimeters)
Green Chromis grows up to 3.9 inches (10.0 centimeters) long and matures once it reaches around 2.3 inches (5.8 centimeters).
This fish has 12 dorsal spines, 9 to 11 dorsal soft rays, 2 anal spines, and 9 to 11 anal soft rays.
Green Chromis is generally pale green to light blue in color. When spawning, its dorsal and anal fins may change to orange or brown color.
Also, nesting males turn yellow, with hues changing during nesting and the back area turning darker.
Green Chromis Reproduction
Green chromis lay eggs (oviparous). During breeding, they form distinct pairs. Males make nests on sand and rubble for multiple females to lay eggs in.
A lot of eggs are laid, and they hatch within 2 to 3 days. Males protect the nest by fanning their tail fins over fertilized eggs and eating any unhatched ones.
