Description
The Blue Demoiselle is a vibrant blue damselfish popular in the marine aquarium hobby. Known for its striking coloration, it can be territorial and semi-aggressive, especially towards smaller or more docile tankmates. It thrives in a well-established reef or fish-only aquarium with plenty of rockwork for hiding and grazing.
