[andy the beginner]

Hi so i picked this coral up.a few days ago. it went in great and seemed fine for a few days. Yesterday morning it had a completely white arm and now it looks like this. Is it too far gone if not how do i save it.

Its currently in the quarantine tank as i wasn't sure a fish caused it.

Parameters are mostly good.
Salinity 1.025
Tenp 25 c
Alk 9.1
Ph 8.2
Phosphate 0.06
Calcium 439
Ammo 0
Nitrates 4ppm
Cant test Magnesium rn could this be the issue?

Have two xr30 on coral growth setting
Tank is a year old 250l ( moving to a 525 once cycled)

Stocked with
Porcupine puffer (small)
Coral beauty
Emperor angel
Two clowns
Dragon wrasse
Pyjama wrasse

CuC
Lots of BTA doing great.
Devils hand doing well
Pulsing xania (NOT PULSING) RN

Doesn’t look like damage from a fish to me. Looks like RTN. Parameters look okay, but it could be due to the coral having too many parameter swings when moving to a new tank.

If I were you I would frag of the healthy part of the coral and get the dead part out. The damaged part will only grow and maybe you will be able to save the other part

Thanks for that. This was it after 4 days in the tank.

Definitely RTN. Parameters all look good. That's a stylo which looks to be a good size! I would also suspect that the colony was used to slightly different parameters (probably alk) and it was swung when you put it in. Bigger colonies tend to not to adapt well in my experience to a new tank like smaller frags do.

Definitely frag off the top piece and try to superglue around the cut to help prevent more RTN. I had to recently do that with an acro that I suspect started RTN due to a small PO4 spike.

If I see it correctly there was already part of the coral having tissue necrosis. It is an uncertain part in this hobby which hasn’t been fully explained. Some talk about stress, others about bacteria causing this. I think the only thing you can do is frag of the healthy part and hope for the best

Would you frag away tje dead parts or *** off all the healthy parts as it seems its at the base of them all.

Snip all the healthy parts and put on new frag plug. Like said before if it’s rtn or Stn it will only grow worse. To save it frag it as fast as possible
