Hi guys

Can anyone help work out what's wrong with my torch coral.  It's been like this for a few days.  I first though it might be sulking if something had bumped into it, but no such luck.  There's an asterias starfish on the side of it, but I don't think it's doing any harm, as I have hundreds of them, so one would have come across this coral a long time ago.  There also seems to be some dark blobs on the tips of a few of the retracted tentacles - could this be brown jelly?

 :cry:

First off i cant see any sign of brown jelly , as a rule it starts to come off in strings as the coralis infected and breaks down and is normaly in response to injury and or infection .


The movement of the Asterina could be annoying it , as far as i know the grey ones are OK ? The green ones are the problem but i may be wrong ,some one will tell us im sure.


I cant see any sign of flat worms tho i once had a Gonipora full of them and it didnt seem to mind .


No changes in water ? not been repositioned near to anything?

It's been in a few weeks, sat next to my Frogspawn - Euphyllia yaeyamaensis .  I believe that Euphyllias dont sting each other, or have I got that wrong?  It's the side closest to the frogspawn that's the problem.  I've moved it to the front on the sand so I can keep a close eye on it for now.

Might give it an iodine dip later to be safe.

I would not stress it i do not know what anyone else thinks?  Just have a good look after lights out to see if there are any sweepers  , and how far they reach, this agression between corals could lead to a dose of brown jelly....


Logically if thier the same family  you would think they might not attack  each other but TBH i dont know, at least you have moved it  now .

another thought , look at it after dark very very carefully for signs of a Tritonia or 2  , in case ive used the wrong word those annoying  white sea slugs that eat corals.

Is it right that you're a long time since last water change?

There could be some minerals depleted they rely on or accumulated something that's bothering it. I don't see any sign of brown jelly either.

It doesn't look like it in the picture, but it's not being battered by flow is it?

Yes this will cause  damage and possibly polyp bail

I think I'll take a look under blues later (although I'll be drunk, as I'm out tonight :cool:).  For now it is in a calmer spot, away from the other corals, so maybe it will recover on it's own.

I did about  20% water change a couple of months ago when I set up the HT.  Other than that, no water changes, ever.  All the other corals are healthy and growing well.  I'll check out a few other options before doing a water change - I really keen to prove their not needed (pretty sure there's a discussion somewhere on here about that).  Happy to be proved wrong, but seems odd that it's just one coral if it's a problem with the water.

Right on the subject of water change im sure you know thier done to reduce nitrate and  bring up levels of certain nutrients cal mag  micro nutrients etc.....


Now if you dont have a nitrate problem  and you have reactors that replace all this or you do balling or similar you dont logicaly need to water change........I dont  :cool:


I ran a Berlin system for many years in excess of 4 or more and it was still healthy when i broke it down and it never had a water change.


If you do have probs with nitrate then little and often is the thing as it is less of a shock to the inhabitants , new salt water is nasty in quantity .

Yep, that pretty much sums it up.  Along with the fact that just by feeding a variety of foods, you add trace elements, as all the algae, plankton, shrimps, etc. are all built of this stuff.

Maybe summat bumped it and damaged it, looks like the head is receeding and about to leave the skeleton.
I'm pretty sure the the frogspawn has sweepers, so it could well be a sting or if another coral is sulking such as a softie it could be releasing "toxins" into the water, all just theory's.
I should really sort this out!!

It seems to have picked up a bit today.  A little more extension.  Not getting too excited yet.

Thanks:
