As if the list of threats to corals wasn’t long enough: climate change, pollution, parasites, and diseases. Add on the Anthropocene, the human age. It all has taken a serious toll on corals.

Aberrant Tangs have been going through insane hype in recent years. Some particular specimens from Indonesia are reaching just nonsense prices. Recently we were lucky enough to observe a unique individual we named the “Dirty Two-Tone Tang” for quite a while on the southern coast of Bali.
At the extreme eastern tip of its range, Acanthurus leucosternon meets with another closely related species: Acanthurus nigricans, the White Cheek, Whitecheeked, or Goldrim Surgeonfish. In this part of its range, the White Cheek Tang is quite common.

Check out these rare Indonesian Micromussas…
