Is this STN on my digitata?

Looks to be.

 

[SomeHappyFish]

What should I do?

 

[PapaFishRocks]

What’s STN?

Asking for a friend, cuz I obviously know….ok it’s for me.

 

[SomeHappyFish]

Slow tissue necrosis, the white part

 

[Mr. Mojo Rising]

What should I do?

Frag off the healthy part before its too late.

Will this make the polyps, come back out?

 

[Mr. Mojo Rising]

No, your just giving it a chance to survive. Its like amputating the unhealthy part in hopes to save the colony, sometimes it will work, sometimes not, but its the best chance for its survival, or else that white will just continue all the way up until its dead.

Okay good but does STN need to have the peeling flesh? Because this only seems to be bleached all round the base, I can still see the polyps.

The white part is dead and with stn it will continue toward the healthy tissue untill the entire coral is dead. Cut above the white / dead part so you have none of that. Glue it to a plug or a rock and hope for the best. I've saved a couple corals this way. It's much better than RTN where I go to bed and wake up in the morning to a bone white skeleton.

Thanks!

Just don't get greedy, cut well above the exposed skeleton and quickly glue it down.

Can I put the sps back at the same spot or I should try another location?

 

[C. Eymann]

Could be tissue recession, but could also be from munching.
'd inspect very carefully when you remove it to frag off the dying base for signs of phestilla nudibranch predation.

That's kinda hard to answer not knowing what caused it to shutdown. Just make sure it has plenty of light and flow. That's about all you can do except cross your fingers.

Will do right away. God I need a microscope soon.

Shouldn't need a microscope for these, although it's a valuable tool for any aquarist to own.
Adults of phestilla are about the size of a grain of rice, with egg bundles being a bit smaller.
Definitely recommend a jewelers loupe in addition to a microscope.
Best of luck!

Did not see any pest, made two frags. The coral felt very brittle compared to my birdnest, but I'm not used to making frags so it could be normal.

Mounted them a little higher and in more direct flow.

May god have mercy on this digitata.
