Chromis and Damselfish are small, colorful marine fish commonly found in coral reefs. Belonging to the Pomacentridae family, they exhibit vibrant hues ranging from blue and yellow to orange and green. These fish are popular in home aquariums due to their striking appearance and hardiness. Chromis, known for their schooling behavior, are peaceful, while Damselfish can be more territorial. Both species play a crucial role in reef ecosystems by contributing to the biodiversity and health of coral habitats.
