Rabbitfish and their relatives

[melkor]

Does anyone have information concerning what is called the "Brown Spotted Rabbit"?
I threw one in my tank about a month ago and only got him out last night. He was introduced to stop an outbreak of Byropsis that had started since he was observed eating it in a LFS (which I had put in there by permission). Well, he left the B. alone but went after the zoanthids first, selective too. After removing all zoo rocks that could be moved to another tank, it started on green button polyps. That I actually was okay with 100% as they had take over a rock and I didn't want them anymore.
Then he began to nip at a 10" Deresa, eating the cilia surrounding it's intake, and making it close constantly. This is when I pulled him out, sadly breaking many SPS in the process.
Having had the Foxface Rabbitfish in a reef before, why does a Fox leave that stuff alone {zoos, clams}, but a Brown Spotted Rabbit go all out like he was a hungry butterfly or angel?
Any help would be appreciated, as I'm real close to becoming a "reef purist", excluding all fish in the future, with the exception of a tang or two maybe.

Most of the rabbitfish can have a tendacy to nip some corals.....but all are reported to be algae eaters. I've had a foxface for a few years now and it has never shown interest in corals or clams.But from what I understand the potential is there. I try to insure it gets plenty to eat and keep a eye on my corals/clams.....but so far I consider mine a great addition. below is a bit of info I found in regard to the scribbled rabbitfish...which may be what you have:
"Scribbled Rabbitfish
Scribbled Rabbitfish, Siganus doliatus, has all of the popular Rabbitfish traits including exceptional coloration, algae grazing capabilities, general hardiness, and overall good demeanor. Also known as the Barred Spinefoot, its displays the “rabbit”-like snout. The Scribbled Rabbitfish is a mottling of brown and white as a juvenile. In adult coloration, it displays closely-woven striations of blue and yellow running vertically along the body. Using their specially-adapted mouths to graze on naturally-occurring algae, Rabbitfish do best with frequent feedings. Main foods provided should include vegetable matter such as Spirulina and other herbivore preparations such as Formula Two Frozen or Formula Two Pellet. Rabbitfish are typically considered reef-safe as they will ignore invertebrates. If not fed multiple times daily, they may choose to graze on some corals, including Soft Corals and Large Polyped Stony Corals. The spines of the Rabbitfish are venomous. So the Rabbitfish should always be handled with great care. Though a peaceful species, Rabbitfish are often kept quite compatibly with more aggressive species who do not bother it due to the stinging spines." :happyfish
