Wall Hammer Coral (Euphyllia ancora) issue...

[Lawrence7]

Hi all, had my tank running for about 6 months now. I bought a hammer coral just before Christmas last year and it was doing well for around 2 months. It's the wall type not the branching.
It's started to come away from the skeleton on the left hand side. It just floats in the flow of the tank and is only attached by the flesh in the middle of the skeleton which seems to be doing fine.

Tank specs:
Red Sea Max Nano - 75l (20 US gal)
AI Prime HD
MP10QD

Water specs:
Alk - 9dkh
pH - 8.15
Calcium - 425
Salinity - 1.026
Phosphates - 0.02ppm

These have been steady for a good time. I also do 10% water changes every week. I also have furry mushrooms and zoas which are thriving.

Please see pics attached

1st picture - This is when I bought it and how it stayed for around 2 months. Opening and closing each night.

2nd picture - This was it at the start of January.

3rd picture - This is it now with the flesh part hanging off from the skeleton (circled).

For whatever reason wall hammers are just not holding up these days, but if you haven't already you might want to research both Polyp Bailout and Brown Jelly Disease/Syndrome just in case.

yea part on the left looks like polyp bailout, and sometimes cleaner shrimp will eat lps

my wall hammers are always a little iffy if their flesh gets damaged.

did you handle them recently? does the flesh rub up against the rockwork as it opens up?

i'd give it an iodine dip and hope it heals before the whole things dies off

good luck!
