STN?

[FishRFriendsNotFood]

Hello reefers,

I have a problem with a nice frag I bought a month ago. When I placed it in the tank it looked like this (the one top left):

A week ago it fell of the rock into the sand and it layed there approx. 8-10hours.
Since then tissue started dissapearing:

Today:

Doesn't look like bleaching, the tissue just gets off the skeleton. Haven't seen fish nipping.

I measured the PAR: 150
I use 2 mitras lightbars.

Parameters:
KH 8,9
pH 8,2
NO3 5
PO4 0,03
Ca 430
Mg 1400
Sal 32,8
Temp 25,2°C

All parameters are the same for months now.
Except temperature, I removed my canopy 3 weeks ago and now my temp stays around 25 Tank is running since april.
I use DSR EZ.

Is this STN? Anything to resolve this?

Stn due to irritation likely
Birdsnest is uber sensitive and usually the first to go necro.

Thank you for your answer, I didn't know it's such a delicate coral.
Can you recommend me a few less sensitive SPS corals please?

For the most part, all sps should be considered expert corals due to their need for a highly established ecosystem.
I even have a hard time keeping most sps.
Then again im a shroom and LPS guy :)

So you mean I have an excuse to buy a lot of LPS next week :D I still don't have zoa's,maybe next on my list now...
Maybe I'll wait a few months before I add more SPS.
Luckily my Montipora digitata is still doing fine

Ya monti digi is fairly hardy
:)
Zoas are great.

Staghorns are pretty hardy. Look for a green slimer

I had a local reefer trade me some coral for a yellow tang he needed for his large frag tank. He gave me a mix of corals. Paly, soft, lps, and a few SPS. These were my first SPS corals and they are doing better than the LPS (frogspawn). I don’t test this tank. Just top off with kalk water and do water changes irregularly.
Red planet acro
Pavona
Green playing monti
Green birds nest

all are doing very well. I was sure the acro would be a failure but it has become my favorite in the tank.
From April 2020 until yesterday (5 months)

That looks great! Did it grow like that in a few months?
