Anyone have experience with them in a reef setting. Would larger ornamental shrimp and feather dusters be safe.
 
What does Christmas wrasse mean to you?

H. ornatissimus, H. biocellatus, or H. claudia?

The answer is dependent.
 
My (well fed) melanurus ate my cleaner shrimp right in front of me. It also killed several hermits and nass snails. Pretty much my entire CUC stayed in hiding until the wrasse buried itself at night.
 
Mine was a perfect citizen. Only till my tank crashed and I looked for another one on line and found it under non- reef safe wrasses did I find out that it was categorized as such. I was very surprised.
 
My melanurus has been fine with a large skunk cleaner shrimp that was in the tank before him; hermit crabs and snails...they have had to get a lot more cautious because he will go after them from time to time.
 
From what little Iven heard and read, Christmas wrasses (which ever species they may be Ornatus or Claudia) tend to be a little more aggressive. My Melanurus has been a perfect citizen since adding him. He gets along with my Radiant, yellow coris, dusky, and gray headed wrasse. Also the key to having cleaner shrimp in with them is to add the wrasse after the shrimp is established in the aquarium. Mine has been housed with a blood shrimp for several years and they leave him alone.
 
Biocellatus stay quite small; are very pretty IMO. I had one for many years.
 
This looks like a decent thread to ask. So what about both wrasses together?
It's quite possible if one is introduced correctly to the other, or if introduced at the same time.

None of the mentioned species are not reef safe; they're all reef safe with caution. They won't harm corals, but they do pose a risk to ornamental invertebrates.

What about H. claudia?
I suppose I was a bit cryptic in my earlier response; I'll elaborate.

H. melanurus, H. ornatissimus, H. biocellatus, and H. claudia all pose a risk to feather dusters. It's variable with any given specimen; some will go after them, others won't give them a second look. It's all a luck of the draw here.

How much of a taste for hermits/crabs or snails H. melanurus has is also quite variable. Some will leave both alone, but most generally find one or the other tasty. And a small percentage will find both tasty, and will regularly go after both. Shrimp are generally safe, but some eat those too.

H. biocellatus is the most mild-mannered of the Halichoeres which might be labeled as a "Christmas wrasse". To me, these are the "Red-lined wrasse", but this is why common names are subjective. Most specimens here will leave your hermits/crabs/snails alone, but there's always exceptions here. Regardless, very rarely will this species decimate your CUC; the safest bet of the bunch. Shrimp are almost always safe with them.

H. claudia only carries a slightly higher risk, and this is the "true" "Christmas wrasse" to me. These get a little larger then H. biocellatus when full grown. Again, they don't generally develop a problematic taste for your CUC, but do expect them to "treat" themselves once in a while. There's a small chance shrimp might be on the menu.

H. ornatissimus, or the "Ornate Wrasse" as far as I'm concerned, gets big, can get mean, and generally gets quite hungry. When these guys get big, any ornamental invertebrate is on the menu. When they're small, they should be somewhat well behaved, but this won't last. With size comes appetite, so don't expect to keep a steady CUC with this guy. And as I said, also with that size usually comes attitude. I'd steer away from this one in a reef tank.
 
Thank you for your response, Hunter. Your knowledge never ceases to amaze me. I think I'm going to give H. claudia and Halichoeres chrysotaenia a shot in my 120 gallon. I'll QT them both together I think and see what happens.
 
I kelp a christmas wrasse and a melanarus together for years in my 285. they got along well maybe only a few squabbles. the melanarus was larger and appears to be on a blue leg hermit crab diet lately. Still have my shrimps and larger crabs. The melanarus has maxed out at 5-6". the christmas was a little under 5" when he exited the canopy a few months back
 
My melanurus has been a model citizen since I added him, never bothered my hermit crabs or coral banded shrimp (although the coral banded is big)
