My experience with this fish is that they are really shy and a great jumper(I lost a huge pair due to jumping ). They are pretty rare in Singapore, usually coming in small no. but very common in HK.
Anyway its a Bodianus Sepiacaudus not a Bodianus Opercularis. B.Opercularis comes from Africa and is very rare while its slightly more common cousin, B. Sepiacaudus comes from the deep water of indo- pacific.
