Randall & Clark, 1993
Very special thanks for the first photo of Helcogramma vulcana to the famous Hawaiiian ichthyologist Dr. John. E. Randall.
Dr. Randall has taken his photo at Manuk, Banda Sea, Indonesia.
Adult Blackfin triplefins are found among exposed boulders of rocky coasts in two volcanic islets in Banda Sea.
Concerning to Andrej Ryanskiy, http://www.diveplanet.ru/, have a look on his wonderful photo of a male triplefin in fishbase, Helcogramma vulcana is also found at the Philippines, but there is no picture on http://www.poppe-images.com, the brothers Poppe live at the Philippines!
Synonym: Helcogramma vulcanum Randall & Clark, 1993
Classification: Biota > Animalia (Kingdom) > Chordata (Phylum) > Vertebrata (Subphylum) > Gnathostomata (Superclass) > Pisces (Superclass) > Actinopteri (Class) > Perciformes (Order) > Blennioidei (Suborder) > Tripterygiidae (Family) > Tripterygiinae (Subfamily) > Helcogramma (Genus) > Helcogramma vulcana (Species)
Jumping guard
A jumping guard prevents (nocturnal) fish from jumping out.
Wrasses, blennies, hawkfishs and gobies jump out of an unprotected tank in fright if their night rest is disturbed, unfortunately these jumpers are found dried up in the morning on carpets, glass edges or later behind the tank.

A small night light also helps, as it provides the fish with a means of orientation in the dark!
