Requesting Torch coral help

[tuajia]

Hi all, been trying to find a solution myself but so far no improvement, need expert advice on torch coral. Long story short, I bought 2 healthy torch corals from a friendly bro. It has been about 3 weeks now, and this is the result

Roaring with life!

Shriveled like yesterday's vegetables...

2 different reactions to my tank conditions. My tank has 2 problems, which are high nitrates and low magnesium levels, but that doesn't explain why the other is unaffected. I tried moving the green around to high flow area, same thing, moved to high light, same. Finally put it in a different tank so I can isolate it (cleaner shrimp keeps dancing on top of it during feeding time). So far still the same. It's in medium flow, tentacles will sway gently and light is moderate. Even when I tried to feed mysis, it didn't even exhibit a feeding response. Luckily it doesn't seem to be getting worse...

I'm running out of ideas, do you bros have any advice for me? Thanks !

Mine doesn't eat mysis. I don't think they eat at all. Maybe phytoplankton but never seen one eat mysis.

I had mine stayed like that for few weeks. Give it time for it to settle and don't touch it or move it around or try to feed it because the cleaner shrimp is annoying it.

Low to Med flow and just don't touch it.

high nitrate is the reason why my polyps are same like yours. So i suggest make a water change or you can test it by putting into a new nsw in another tank

Different pieces of corals (even if same species) can react differently even in the same tank conditions.  Some are just more sensitive than others and react more negatively to the shock of changing tank.  If you know you have high nitrates and low magnesium, try to bring it under control, and see if the coral react to it after a while.  As long as the tissue is not receding inside its head, you are still generally safe.  Just give it time.

Thanks for the advice, people. Guess I also need to dose myself with patience supplement

How high is high nitrates?

[tuajia]

Around 15-20ppm, weekly 10% water change

Update. So far my torch hasn't recovered, in fact the tentacles have become short and stubby. Flesh isn't receding into the skeleton though, so it still seems ok. However the shape seems to be changing. Does this mean anything? It now looks like a bit like a clover shape that the initial oval shape...

can you show us a pic of your whole tank ? maybe guru here can advise you where to place your torch

I moved the torch into a 30 liter nano... You can see the torch is at the bottom right next to the sun corals. The outlet is on the left so the flow bounced off the glass and hits the bottom, moderate flow.

But I suspect something funny is happening at night. Notice that a xenia is in between the torch and the suns. My naughty damsel knocked it down. Since the torch is so reduced... I left it alone. That was a big mistake... The next morning, I saw a pale white xenia with almost all the heads burned off... Quickly moved it to a far corner. Seems to have recovered but so little heads now

Is this a classic torch attack? If that's the case, doesn't that mean my torch is actually opening up at night and whacked my xenia with its tentacles??

Could be. Torch have tentacles and definitely attacked your xenia.

Update: Torch coral started receding into the skeleton a few days ago, which is bad news. Then suddenly, i spotted this small white pearly smooth thing. Is this some kind of parasite? It looks like a smooth white pebble. Thanks guys, am gonna attempt to rip it off. Its stuck on quite hard.

Lol latest update. The torch is totally dead now. But that strange thing is new one solid strip around the rim. Looks like a piece of blue tack stuck on it. I just left the skeleton in the tank
