Description
The Bicolor Damselfish is a hardy and vibrant marine fish known for its striking blue anterior and yellow posterior coloration. It is a popular choice for beginner saltwater aquarists due to its resilience and relatively small size. While generally peaceful, it can become territorial, especially towards similar-looking or smaller fish.
