Mine was sold as a Japanese, but is possibly a Hawaiian. In fact there is no real Haw or Jap, just Dragon Morays of varing colors.
Mine is pretty peaceful, I've even kept him with a Flame Angel, Majestic Angel, and even Damsels. Never an issue. Much better than a Tessie (but I love them too, and want one so bad).
Here is mine..30" and growing.
