Kala or Unicornfish

Kala or Bluespine Unicornfish

And as is the case with the Sleek Unicornfish - not visible at all. Kala or Unicorn Fish. Like the Surgeonfish, they have several spikes at the base of their tail used for defense and fending off competitors

They are generally greenish grey in color. The males have streamers running from the back of their tail fins.
