Sudden loss of some candy cane heads

[Shooter7]

What would cause the sudden loss of some heads of my green candy canes? I have a colony of about 20 or so heads and looked fine last night. Today I get home from work and 4 heads are completely brown with what looks like tissue peeling off of them, right in the center of the colony. Rest of the colony looks fine. I'm a bit baffled. thanks

anybody....anybody at all....?

Nobody in here knows what this could be from?

Got pics?

Did you add anything new to the tank recently? Change lighting? What's the temp?

Other parameters? What other corals do you have? Anything in stinging distance? How are the other corals doing?

Enough questions??

I'm contemplating the possibility of another LPS in the general area possibly having some sort of sweeper tentacle that could be getting him, but haven't seen this happen before to corals in the vicinity of this other LPS.

No, nothing new added - well, except for starting to run a canister with carbon and PHOSaR a couple weeks ago. Tank has been up and running for 8 months having used established cured rock from other tanks. Ammo is zero, nitrates and phosphates are undetectable per salifert. Temp is 80 - 81. Magnesium is a little low on last test, in the 1150 range. Need to do a water change, but getting ready to do a sump revision so I've been holding off. Any other ???'s

oh, and no, don't have a pic handy right now...I'm at work.

What's the other LPS? How close is it to the CC?

Actually, it is an LPS I don't have a specific name for other than what Griss told me it was when he gave me the frag of it a year and a half ago, said it was called an "Agu Thingy". Basically, skeleton like a frogspawn with inch to inch and a half long individual polyps.

"Agu thingy" can be deadly. No wonder George gave you a frag! :lol:

Just kidding. I know how sensitive those guys are.
If all of your other inverts appear to be OK I'd strongly suspect that your "Agu thingy" has developed some sweepers...

After some observation, I think the Agu Thingy was the culprit. It's been growing and its polyps were brushing over towards the candy canes in the current. One other thing about it, I went to try and move it to a different location and it has quite thoroughly fused itself with the rock it is up against. So, I had to alter the little moving plans I had.
I cut out the dead heads, the rest of the coral is fine. Will have to remember the permanent positioning of "Agu" for future revisions.
