Help Hammer Coral???

Hammer on the left, is it dying, dead, just not happy! My salinity spiked this past weekend, I reduced it with water changes, but his guy along with my Duncan’s went it defense mode I guess and hammer hasn’t opened back up yet not 4 days later? I can move to a different tank but the Duncan opened back up and fine . My zoanthidd are still closed as well. Corals confuse me!

Zoas up too. This all in my 14g biocube.

If there is flesh then it's still alive. Be patient and don't make any other big changes and let it adjust.

It’s hard to keep stable salinity in small tanks.
I would leave them a lone and don’t move them.
Some zoas are bullet proof.

How olds the tank? Doesn’t seem to be much coraline in there, also your light recently died and you swapped to a diff light?

I have had this tank for many years but let it go during Covid and started over a year ago. The old hood was a mess ie all stopped working so removed hood and dropped the Coralife led light on it when it was fish only. Added some corals over the time as I had great luck in my larger 32g bio with leds and so the corals have been doing fine in this for ~6mos but last weekend I added a pin cushion and a Pom Pom crab and they didn’t make it the night. Floated the bags, Drip’d, water, etc. then the next am my cleaner shrimp bit the dust. Checked all my levels, realized my salinity had sky rocketed, others were fine. Water changed with fresh water and all well salinity but the hammer and zoas remain closed.

I think if you already fixed the issue you should just wait and see… I know it’s not easy to see a coral you like look bad!! I hope it recovers
