Description
The Onespot Demoiselle is a hardy and territorial damselfish characterized by its light grey to yellowish body and a prominent black spot, often outlined in blue, at the base of its dorsal fin. Native to the Indo-Pacific, it is a relatively small species that can be aggressive towards tankmates, especially those of similar size or appearance. It thrives in established marine aquariums with plenty of rockwork for hiding and grazing.
