need help, possible coral disease

[dimidragos]

Hello , yesterday evening i notice this change on the left side of my coral .Today it's a bit worse. Please look at the pictures:

It's one of my favorite coral because of his bright color and also because growth very nice.
My water parameter: Ph 8, Alk 9.6, Ca 1450, Mg 500, No3 0 (all Salifert), Po4 0(Hanna ulr), Salinity 1,026.
My tank it's 3 months old and i'm beginer.
I feed the corals two time on week with Seachem Zooplankton. It's a mixed reef tank, mostly Lps.
What can be??
What can i do??
Shuld i isolate the coral and remove from DT??
Please advice me

Is there another coral near to this one that might be sending out sweeper tentacles at night?

Looks like brown jelly. I would advise to use a turkey Baster and suck up that brown jelly stuff to prevent it from spreading further into to the coral.

Im guessing the coral to the left is sending out sweeper tentacles at night.

That will be the easy way to solve the problem but the coral on the left have small tentacles. I will take a closer look, it's midnight here now. I will se tomorow how looks
Any other opinion or ideea wil be helpfull
Thanks to everyone!!

Look now, at night is when the feeding (sweeper) tentacles come out.

I would monitor closely for now. The coral still looks very healthy. Perhaps, like others have said there’s some coral wars going on, that has injured your coral in question. The small injured area then turned into brown jelly. So best to suck all that up so the brown jelly won’t spread to surrounding areas.

If you have already identified the cause for coral injury. Try to separate them the sooner the better. I don’t know how many times I’ve lost a coral overnight due to them stinging each other.

Move now. They look little most the time. I’ve realized that some of the smallest LPS put out the biggest sweepers. It should heal up just fine once it stops being stung.
