what is the reason my touch coral not sticking on the rock

[zebradanio]

May i know the reason why my touch coral not sticking on the rock after few month? because high flow? or not enough mineral/food? The important thing is the coral meat didnot melt, just not sticking on the rock.

Touch coral = torch coral or what? Pls clarify, haven't heard of touch coral before...

Torch coral? Like this one?

If you say the torch coral is not sticking on the rock then I'm confused. Maybe you can clarify what you actually mean.

[zebradanio]

yes, i mean torch coral. As per picture.

I suppose you mean the flesh of the torch corals fell off their skeleton. In this case, most likely due to too high currents blowing at the torch coral.

Check your temperature. These corals don't do well when temperatures go above 28 degrees long term.

wow this is the first time i'm seeing this!! full tissue bail out from euphyllids! did the entire polyps just float out of their skeleton and land elsewhere? i've only heard of this "skeleton bailing" in elegance corals so far. The bailed out polyp can settle and grow a new skeleton. but in the tank it is highly unlikely and the chances are next to zero. in the wild they do this to escape stress. In the tank, you need to identify the stress factor first

something is not right here thus this phenomenon. while there are a thousand and one reasons why it's not right, it's too much to state. so i will just identify the basic requirements of these coral so you can identify what's wrong.

medium flow - the polyps should be waving around, not trashing around.

random flow - no laminar flow to avoid tissue tearing

medium to higher lighting - if using MH, shade it. they prefer med lighting

feeding - they need to be fed lightly, like mysis. once every 2-3 weeks

parameters - ensure proper calcium, magnesium and kh levels. these corals are more sensitive to these parameters

temp - dont go above 28. ideally 27

"Polyp bailout is the process where some stony corals eject themselves from their skeleton and drift to a new location. Once the polyp settles, a new skeleton is formed and a new colony begins. Bailouts are almost always a response to stress and is often a last ditch attempt for survival. If you notice the bailout of a coral in your tank, it may be time to do some additional testing to see if there is a problem in the reef tank."

Thank for information, anywhere i had switch off my wave maker now. by the way, my tank temperature always setting at 26 degree so i dont think is temperature problem. (The problem is recently i had switch off the chiller full day when i am study beside the tank because noisy and feel hot).

what i can do for the flesh fell off the skeleton? one by one fell off the skeleton at the moment, my base of tank got few flesh already!

you first have to fix the root problem so that this will not happen again.

as for the flesh at the bottom, pray that they grow a new calcerous skeleton like they would in the wild. very unlikely because in the wild they do this to find favourable conditions. in your tank, it's same condition everywhere so very unlikely they will survive.

One of the link I posted attributes the causative factor as low pH. You might want to check if your pH is at normal levels.

[DUCADOS]

Agree with with lemon. For coral,lighting n temp very important.

Other than checking what others suggested.

check Ca and Po4.

i experienced LPS deteched when Ca is too low or PO4 too high.

and it might be due to infection as well.

all the best.
