Aarghh! What Happend To My Duncans?

[Anguilla82]

hi all,

well my duncans look dead!
which is rather strange as last night they looked fine and like this:

heads out and brown colour to stems.

This morning they look like this:

what can happen over night to make them look like this?

all other fish and corals are fine as are my shrimp, though my new mithrax crab is also dead (could this be related?).

all stats as of yesterday are fine though not checked them yet this morning, but don't see how they can be any different over night. Didn't even feed last night.

please help peeps!

Has it been stung by another coral over night?

Mine stayed closed for a couple of days when it split a new head though but I am only a novice

shouldn't have been. there is nothing close enough to have stung it.
it was growing a new head on the side but just seemed to be doing that with no other problems.

That seems very strange Rob

I would check your levels.

If it was something to with the demise of the crab, I would expect more than one coral to be suffering.

The stem on mine is not brown so don't give up on them yet.

I had problems with mine as you correctly recalled in your journal, I am not sure whether it looked like that though.

Give it a chance, once they have settled, they seem bomb proof, but can take a while to settle.

How close to the light is it Rob??

its right at the bottom of the tank on the right hand side.

 

[TigerIssey]

If it right at the bottom, it could not even be down to light bleaching.

Give it a few days and watch it closely. If you see any tentacles emerge, feed them.

Other than that ATM I am stumped.

i lost a head of my torch exactly like this, no explanation what so ever

 

[Anguilla82]

cheers everyone.

its just so weird that its happened over night, but only to one coral.
I can understand it if i had a massive ammonia spike or something but all of my other corals/fish would be sufferring also?

got me stumped too

 

[seffieuk]

Oh heck, I hate these unexplained things...............mind you I also hate the explained deaths, so

but doesn't look dead to me, do duncans sulk?

[ben1987]

they do, thought i had lost mine at one bit. fell into the rock work without me noticing. Then dug them back up. They were no where near as far retracted into the skeleton as that though.



is there any fleshy bit left in there rob? as they are really really hardy

 

[Anguilla82]

there is some right at the bottom of the craters, but they've not come out all day.

am fearing the worst to be honest, but will leave them there till they completely go over just in case they come back.

 

[Anguilla82]

well happy days , i don't think they're dead!!!!!

looked this morning and the heads are at the top of the skeleton, not sunken, and the polyps were just poking out.
skeleton is still white rather than brown.
Not back to normal yet but certainly on the way i hope!!!!

could the loss of colour of the skeleton be down to a massive release of zooxanthellae? and its sulking after this release?

 

[TigerIssey]

Not sure there Rob, I thought the zooxanthellae were found in living tissue such as the polyps or tentacles etc, whereas the skeleton is calcerous dead tissue.

Good news though

Give them a feed later.

Is it posible that your light are far brighter than from whence they came?
