Peppermint shrimp messing with Acans?

[Oldsalt01]

When i got home from work tonight i realized it was feeding night for the fish. Shut down the return pump, fed the fish some Hakari Bio-Pure mixed with some Calanus, as I do every other night. Just for drill, I spot fed the Acans and they started feeding! Not the damaged heads, but all the others got FAT! So, I've got my fingers crossed that they'll make it through. I just ordered some Reef Roids. I'm afraid I'm hooked now. This could become an obsession!!!. Thanks to everyone for your support and input.

I just ran into the same problem with acropora. Kept trying different things thought it was water chemistry even though I was on top of it and my tests were good. 1 night I finally got to see the peppermint shrimp I added to the tank over a year ago sitting on top my slimer acro. My garf bonsai looking acro was almost fully annihilated lost hist about all color to a pale white except some of the base and a couple branches still had color but it did not rtn or stn. The Walt Disney I did lose and a couple other pricey little frags. Since I caught the shrimp with a Pepsi bottle I had to leave in the tank for 2 days to catch him, everything has been doing better. All corals that were losing colored tissue are all slowly regaining color.
I never had issues with peppermint shrimp before. I just recently came across a thread that mentioned them and read the whole post and determined I would try and catch the shrimp late at night and see and sure enough eating away it was.

The shrimp were returned to my trusty LFS. It was either that or have them for dinner. I got my Reef Roids yesterday, fed the fish, corals and zoas last night. Now it's a matter of waiting to see if the damaged heads heal. The undamaged piece and my zoas pigged out on the Roids and are looking good this morning. While I was feeding, I watched a small bristle worm come out from under the damaged piece and do some housecleaning. I think I'll leave him in there for now. I don't believe he's a threat to the corals.

I can confirm these little s**ts like acans. I had several disappear overnight. Finally I checked just before the lights went out the sure enough there was a peppermint shrimp going to town. Thus far they have only bothered the acans. I moved the carcasses to the sump but I don't see any regrowth. I have zoas, euphyllia, favia, moseleya and goniopora and none of those have been touched, thus far. I did have one ricordia that disappeared while I was on vacation. Who knows if it was also a victim.

Yah. I lost the Acans, gave the shrimp back to my LFS, tore down my tank due to a serious infestation of Bubble Algae because my Phosphates were thru the roof, replaced the rock and was lucky enough to avoid a cycle. The tank's back together with new rock, no BA, and I'm hoping to move all the fish back in by the end of the week. Be sure I'll be closely monitoring my parameters from here on out. Since the shrimp left the people eater zoas have gotten a little bigger, so I'm wondering if the shrimp were irritating them too. From here on out the only shrimp I have will be on the 'barbie.

I've had dozens of peppermint shrimp, and most were great. But I got two recently that developed a taste for lps. They killed a plate and a frogspawn and I left them in as the corals declined because I didn't believe it could be the peppermints. Finally banished them to my sump and had several lps make an immediate recovery.

I have hope for your acans. They can make dramatic comebacks especially when fed.

Peppermint shrimp are the devil!!!! Ate my Walt Disney and almost fully annihilated a few others before I saw this post back in summer. Did the same as everyone waited a couple hours after lights out and caught it eating my slimer. I never saw that shrimp since I added it over a year ago til that night.
