Coral tissue bleaching

[Jwheld]

What is happening to my trumpet coral??? It's been in the tank for 2.5 weeks. For the first two weeks it fully extended its tentacles at night and not as much for the past few days. I just noticed the tissue recessing or bleaching this morning. Will it make it?

Am=0
Nitrite=0
Nitrate<2 (dose sodium nitrate as needed)
Alk=9.3
Cal=425
Mag=1300
SG=1.025

I don't see the bleaching in the picture. Are you talking about the base or stem or the actual green flesh is bleaching? I can usually get mine to extend by basting some Mysis or reef roids near them.

The white between the skeleton and green. It used to be green there, now white.

Seems fine to me

We are in the same boat. Mine followed the same course and looked much worst than yours. Even the tissue from polyps was stripped.
I was not feeding anything and then tentacles stopped appearing at night.
I discussed it with a fellow reefer and started feeding at nights. It took few days and then tentacles started reappearing. It now seem little better everyday.
Once my tank lights go off and it's completely dark. I give it one hour or so. Then turn on the room light and not the tank itself.
Turn off the flow. Mix some small food and just a small squirt on them. Wait 5 minutes and then turn the pump and flow back on.
I fed reef chilli. But i guess any small food will work. Mysis shrimp should work as well.
Dont touch them!
Dont move them from sand for now.
You should definitely see some response in a week or so.

Mine are looking little better than before. But still long way to go.
Lets keep each other posted!

More fluffed up and starting to divide.
Good polyp extension at night.
Whats the update at your end.

the white is skeletal growth, right?

Or tissue recession. You have to watch the coral over days to figure out what is going on.

Tissue got a little worse but has been stable for the last few days. Looks like good tentacle extension at night. I'm still trying to feed every other night.

There must have been something going on in the tank because right after the last post my frogspawn didn't extend for three days. Now that is looking normal.

The coral doesn't seem to be dying. Has it gotten stressed out recently? (i.e. a small spike in salinity or nitrate levels).

I didn't measure a spike in any parameters. I put new carbon in a media bag and a water change and the frogspawn looked better over night. Must have been some dissolved organic soft some type, I'm guessing. Waiting for the trumpet to bounce back and start growing.

Corals can do strange stuff few days without any reason. As long as Frogspawn doing okay now, nothing different needs to be done. Frogspawns are known to be finniky!
For trumpet, it looks ok. I would say just sit tight for another week or so. It will turn around.

Sounds good! I'll let you know.
