Help with new acanthophyllia

[Jakeem]

Just got this meat coral yesterday and has been in the tank for 24 hours. Today it seems like there is this brownish patch growing in the centre of the coral and white skeleton is protruding.

The coral is placed at the bottom of the tank next near acans not touching whatsoever with low flow. Its currently sitting at the bottom of the tank with full light aswell.

Is this a sign of too much light? My other corals seems to be doing well.

Parameters
Alk 9
Calcium 425
Magnesium 1425
Phosphate 0.08 ppm
Nitrate 0
Salinity 1.025
Temp 24.5 Celsius

The light is currently a radion xr30 pro g4 at 45% intensity, shoyld i lower the intensity and slowly raise it back up?

The coral was drip acclimated for 2 hours and then was dipped and floated to stabilize temp, also dont seem to see any animals picking on it either and dont notice any pest

I'm not really sure about the color, although this could be due to the lighting, but you might want to find the coral some shade for a week or two and see how it responds. Sometimes it can take awhile to find the "sweet spot" so to say. I guess you could lower the intensity, but if everything else is OK then why mess with a good thing? GL.

I agree with finding it some shade. What I do is take several squares of fiberglass window screen and put a few layers of them on top of the screen top to create a shaded area wherever it is I decide to place the coral. That way you can put them in their permanent spot now and allow it to get acclimated to the new flow patterns at the same time it's getting used to the lights.

Ok thank you for your help, would you say the brown spot is something to do with too much light?

 

[ramseynb]

It doesn't look like it from the picture, but is the brown spot slimy looking? If so, you might want to research brown jelly disease. From the pic, it doesn't look like it, but thought it's mention it.

I agree with putting it in the shade somewhere and see how it responds.

 

[Jakeem]

the brown spot seems to be the tissue turning brown, nothing on the tissue. But also very worried on how deflated the coral is currently.

 

[Jakeem]

Update, the coral hasnt been much better and the brown spot seems to be growing, also notice really thin white threads on the center of the coral and doesnt seem to be worms. Tried to blow if off but it seems stuck onto the corals tissue.

Any ideas would help thank you

 

[AlSimmons]

Those white threads your seeing are Mesenterial Filaments. (basically the corals guts) Sometimes these are used as a defense mechanism, other times it could just be an indication that the coral is not happy.

This is likely what has done the damage.

To be honest I never drip acclimate corals. I float the bag for 20 mins, and then goes to the tank. SPS coral mostly get dipped it for 5 -10 mins in between. I generally dont dip LPS corals.

A store should be keeping their corals around ~1.025 anyways and my tank is at 1.026. There is no reason for dripping.

Depending on the bioload of the tank the frag came from, the amount of organics that made it into the bag, and how long it was in the bag before it was opened. A 2 hour drip is a death sentence for anything.

Jakeem,

Anything in your tank that might be repeatedly picking on this little guy?

 

[Jakeem]

As of now, i dont notice anything interested in the coral or going near it either. the coral was bought from my lfs and was only in the bag for around 40 mins

 

[AlSimmons]

Did you move the coral or is it still in the same spot? Has the lighting been changed or subdued at all?

Dripping a coral for 2 hours won't kill it but it's also totally unnecessary. I normally dip all corals but I'll use half tank wAter half bag water. 15 mins dip in clean water into tank. I go a little slower with anemone. Also maybe you over dipped it. Meat corals do like lower light I wouldn't move the coral. Moving a weak coral all around does more harm than good. Radion have a coral accumulation program it's totally safe and ok to use it
