Rabbitfish -yes or no?

[euromomtx]

I have a 125g reef tank primarly devoted to sun corals, gorgonians and small fish.
Unfortunately I also have caulerpa in the tank. I hate it. I pull a large amount of it out every week.
A long spine urchin does nothing for it (or against).
The only other suggestions I was given was:

• tang
• rabbitfish
• sea hare

I got a tang and it didn't eat the caulerpa. It also was very hyper and scared my clownfish into the overflow several times! It was a total PITA to catch that tang and get it back out of the tank. Took a whole day.
I like the sea hare idea but everything I read seems to imply they eat hair algae. I don't have hair algae. I have bubble and caulerpa
So I am considering the rabbitfish.
Will it be hyper like that tang?
Will it threated the clowns with it's spines like the tang did with its scalpel?
Will it hurt corals, shrimp, clams, etc.?
Will it eat caulerpa?
If they all differ I think the Fiji Bicolor looks nice but I'm open to suggestions.

My rabbittfish is quite docile. I don't know about calupera . Mine has never bothered inverts.

My rabbitfish is pretty much oblivious to its tankmates; it doesn't harass any other fish.

I wouldn't describe it as hyper, but it moves quickly when startled.

It does take an occasional nibble at a softie, but was fine with my clam and shrimp. I can't speak as to whether or not it will eat caulerpa, as I don't have any in my tank.

I have had 3 one spots and all of them loved caulerpa.
I have had them in mixed reefs and I have one now in my 180 sps.
Great fish, never bothers anyone unless bothered and then it just spread its fins and points at the offender and dares it to try it, lol.
They eat like pigs and grow kinda fast though. Mine will eat as much nori as I give it, at least once a day.
