Phantom Blenny

The Phantom Blenny is prized for its voracious appetite for nuisance microalgae. But the Phantom Blenny is most recognizable for its stark black colouration on both body and fins. Since the Phantom Blenny eagerly perches upon live rock to feed, Atrosalarias fuscus truly creates an eye-catching addition to any saltwater reef system. 

Native to the reefs of Java, the Phantom Blenny requires ample live rock with microalgae growth on which it can forage for food. This member of the Blenniidae family is an obligate microalgae eater, which means it needs microalgae in its diet in order to survive. However, its diet can be supplemented with vegetable matter, including frozen and dried foods containing marine and blue-green algae (spirulina). 

For the best care, house the Phantom Blenny in an aquarium of at least 30 gallons. The Phantom Blenny likes to hide amongst rockwork and inside caves, so offer a variety of locations in which the Phantom Blenny can find solitude. When properly cared for, this species of Atrosalarias will consume mass amounts of hair or string algae. The Phantom Blenny is peaceful towards tankmates of similar size and temperament. It may nip at some small polyp stony corals and clam mantles, however. Also, the Phantom Blenny may be territorial towards its own species; therefore, if incorporating more than one Phantom Blenny into an aquarium, it is best to acclimate them simultaneously.

Males are generally larger than females and experience a succession of color changes when breeding.

Juveniles are a bright Yellow colouartion.
