Description
The Atoll Demoiselle is a hardy and attractive saltwater fish known for its distinctive two dark spots and blue-grey body. While generally peaceful with larger tankmates, it can be territorial and aggressive towards smaller or similar-looking fish. It is a good choice for beginner to intermediate marine aquarists.
