It is indeed one of two species known as the humuhumunukunukuapua'a, the other being the lagoon or Picasso triggerfish (found in grossebertha's Triggerfish Pack 2).

It is given the English common name of reef triggerfish in game as in the mod description, however, to avoid formatting issues.

Isn't this fish also called a Humuhumunukunukuapua`a? It better not be called a Humuhumunukunukuapua`a in game, or I think that amount of text may break something.
