Need some help figuring out what going on with this branching hammer...

[Jeto2004]

Coral is in the tank for 4 month, completely opened up in the beginning but recently doesnt show full polyp extension but doesn’t retract either. Tissue is all around the stem. Polyps seem to be shrinking . Other hammers around it are doing well.

Salinity 1.026
Temp 78-79
NO3 5 ppm
PO4 0.12 ppm
Alk 8.54
Ca 485
Mg 1350

That bubble coral looks really close. It doesn't look like it has been stung but that is something to watch out for.

Is a wall hammer - currently they are not touching but have in the past.

Hi,

Numbers look good. Anything new put in tank? Any new changes in lighting or flow? Last question I promise. Do you feed them or dose anything?

Has the flow changed or have you made any adjustments lately or added anything new. As long as the mouth isn’t gaping and the tenticals going inwards vas shrinking your coral has a good survival chance. I would bring your phosphates down to like .08 and your nitrates to 2ppm your ratio is way past the 1/16 ratio.

Added new corals , but this is going before I added more coral. No change in lighting or flow. Dosing Reefenergy AB+.
Don’t mind the question, I’m asking for help...

one more thing - the mouth is not in the middle anymore and instead there is a smooth dome shaped surface

Does the mouth look like this

No. Lights are out will try to get an image tomorrow.

I would have guessed it's splitting because of the "dome/bubbling mouth". One of my hammers look similar, with parts fully extended mixed with pretty retracted. I will try to get an image but it usually happens later when the lights are dimmer.

every time I ever seen my frammer or torches split it usually started with the mouth extending horizontally a little more than normal and gets wider till it slowly would split without the tenticals seeming to shrink. There’s even time lapses of Euphyllia coral splitting online that show similar results.
