Damselfish

Damselfish are always active, bringing life and enjoyment to any aquarium. They are hardy fish and great for beginners.  Furthermore, damselfish are beneficial to reef tanks because they graze on algae, without notably disturbing corals. While some damsels, such as Sergeant Majors, are agreeable with other marine fish, others, such as the Jewel damsel and Beaugregory damsel are more aggressive.
