Ambon Chromis, also known by its scientific name Chromis amboinensis, is a type of damselfish found in the Western Pacific Ocean.
Sometimes, people keep these fish in aquariums. Adult Ambon Chromis live in clear lagoons and seaward reefs with lots of coral.
These fish are mostly found on steep outer reef slopes deeper than 24 meters but are not common in lagoons.
Young Ambon Chromis like to live in large branching corals while adults prefer caves.
These fish are active during the day and gather together in groups.
Ambon Chromis are safe for coral reefs and don’t harm them in any way.
