This video is called Saltwater Fish Species – True Percula Clownfish “Amphiprion percula” (Full Bar).
From Practical Fishkeeping:
This monophyletic origin for the subfamily Amphiprioninae is at odds with morphological taxonomy, which splits the subfamily into two genera: Amphiprion and Premnas.
Although most fishkeepers are aware of only a single species, the Maroon clown, Premnas biaculeatus, the Premnas genus actually contains three species: the other two, Premnas trifasciatus and Premnas leucodesmus, are rarely imported.
Morphologically, Premnas are rather different to Amphiprion species and have a prominent spine on their opercula or gill covers, which is absent in Amphiprion.
The molecular evidence for the monophyly of the Amphiprioninae seems to suggest that all members of the subfamily could be members of a single genus.
The study is the largest done on the Amphiprioninae to date and analysed the genetic material of many species never previously studied in this manner.
ScienceDaily (Nov. 7, 2012) — Clownfish produce sounds to establish and defend their breeding status in social groups, but not to attract mates, according to research published November 7 in the open access journal PLOS ONE by Orphal Colleye and colleagues from the University of Liege, Belgium: here.
Clownfish boost oxygen flow around their anemone hosts at night, scientists have found: here.
