Blue head wrasse

[kien]

although I have not owned this particular wrasse I have owned pretty much all others of his family that are generally available, that is, the Thalassoma group of wrasses.

In my experience Thalassoma's are generally not invertebrate safe. All the ones I have owned (Banana Wrasse, Pink Face wrasse, Lunare wrasse) have enjoyed meaty foods like shrimp and snails. They don't generally go after corals tho so I think that's where the semi-reef safe or 'reef safe with caution' comes into play.

As far as aggression is concerned they do tend to be more aggressive wrasses. My Pink face and Lunare wrasses were a mean SOBs while my Banana wrasse wasn't as mean.

Having said that, we are talking about fish with personalities so I'm sure there exists Thalassoma's that are well behaved. I just have never owned one myself :-)
