candycane coral help

[10gnano]

Hey guys
I have noticed lately that my candy cane coral have been retracting. The green part has been getting smaller and smaller as the days go on. I can actually see what I think is the skeleton protruding through the green fleshy parts. notheing else is reacting in my tank. any suggestions. I have 6 heads and they are all doing it

[Vincenzo.]

they might be dying. have they recently been moved?

[10gnano]

no infact they are pretty well established, this sucks

[Vincenzo.]

param's?...

[RoxyDog]

Tap water or RO? 

[Hookup]

They are a very hearty coral and this should be a cause for concern.

As above, Param's are your most likely suspect.

Flow and Lighting are also a factor that can cause this type of reaction, however because it hasn't moved, it's unlikely that these are the issues.

Do you skim?

What is your;
pH
Salinity
Ammonia
Nitrite
Nitrate
Ca
Alk
Mg
Phosphate

A full range of tests would be helpful.

It could also be chemical warfare between other types of LPS corals. Do you have Frogspawn or Torch corals? I recently lost my Candy cane colony after adding a Torch to my tank. The torch apparently lost out to the Frogspawn, and the resulting toxic soup killed off my Candy cane and Hydnophora. I suggest water changes and adding or changing Carbon.

i just changed my carbon, i will do a good couple of changes over the next bit

I had the same problem with my candy cane. All params were fine and all other corals were not affected. I was so confused as to why only my candy cane was dying. Until this day, I was confused. Then after reading this, I figure it was probably due to the addition of the torch. Damm chemical warfare!

may the strongest survive.

See I was waiting to see if he used tap water as you and I do.  I had extremly happy and healthy candycanes living with two kinds of torch corals in a 40gal tank with no problems.  At some points they were even right beside each other.  Now that I use tap water, some kinds of candycanes have withered away while others thrive.

Well, I have both a torch (5" away) and hammer coral in my 90g.. no issues.. all happy, all growing...

[beertech]

Yeah, I think everything will normally be fine until one of the more agressive LPS corals gets stressed or aggravated somehow. Then the battle begins. I think in my case the Torch was weak already, then added to a tank with existing LPS. As it was on it's way out it was releasing toxins into the water.  Also, I missed what size tank 10Gnano has , is it actually a 10 Gal, or have you upsized?  Small water volume plus agressive corals equals a very delicate situation.  Interesting note though, I also use tap water ( I'm in Kanata), have for 8 yrs now, always had mixed reef with multiple LPS, and no issues until adding this one Torch in particular. 
But, hopefully this was a one time issue, and things will be better after water changes and carbon.

i have a 15 gallon nano, i hope thats all it was was the frog geting pissed, I use RO water as well
