Euphyllia eating fungus?

You also can see microholes where they are cause part of them get deep Inside skeleton

It was in indirect light, low flow, away from other corals, received Lugol's dips and I even fed it LRS to try and perk it up- nada. I've since removed it from the tank, it's in a cup with an airstone for now (was not willing to risk the rest of the tank any longer). How should I try the Methylene Blue test? Dilute it in water or scrape some of the fuzzy stuff off into straight MB?

Lugol its useless
You can diluite in water use ro water and some drop of bm

Dissolved nutrients might be the only way to go if the polyp is too irritated from this. I wouldn't try to feed him chunky stuff until after he's recovered more. I would make sure there were PO4 and NO3 in the water in some degree.

Looks like it was too late to tell. I checked on the coral this morning and the water looked clear and it seemed okay. Just went to get it to do the MB test and it smelled foul, it was a goner. I had no other tank to put it in and couldn't risk my tank any more than I had so that was the best I could do given the circumstances.

I put the Torch on a paper plate and applied a drop but it didn't change color from what I could see. It wasn't in water so it wasn't its usual shape either, it was more like snot instead of fuzzy. Not sure if that rules out the zoo/fungus post or not.

 

[mcarroll]

Interesting....and too bad....but at least it was isolated!

 

[StrangeDejavu]

Indeed, I just hope this is the last I see of it. Very weird how the other LPS in the tank are thriving but this guy just went downhill quick. Here are the other Euphyllia in the tank and they're loving life, look at the Octo's extension.

U speaking of boring algae?

I haven't read up on them specifically, but from how they get mentioned in the stuff I've read, they seem like they're ubiquitous....part of the usual cadre of coral symbionts and commensals.

So you're theorizing this might have been an explosive growth of boring algae?

(I have seen this on Euphillias before too, not that it helps anything.)

This stuff attached to this torch doesnt look like this boring algae in the links.

[bios]

@mcarroll dont know exactly english name
Those are present on large number of LPS as commensale
Theyr explosion on a coral must be from High light exposition
And presence of phospates

 

[bios]

No stev different they dont attack SPS only lps

 

[mcarroll]

Are you saying it's a different type of algae, or are you saying it's a type of boring age but you just don't know the name?

 

[stevo01]

I read the green Siphonous species of the ostrobium genus is most common. Think this might be the one on acros. Im looking into species of the genus now.

 

[bios]

Are algae that i call endolitiche
Those live normally as commensals on coral scheleton and have a low grow so coral deposit more calcium they adsorb
Theyr explosion cause cpral distruction

 

[mcarroll]

I think that's equivalent to "endolith" – meaning to live within rock. It's a generic term though – can refer to bacteria, fungi and viruses. (From reading...just saying to confirm we're talking the same term.)

From...

Maoz Fine, George Roff, Tracy Ainsworth, Ove Hoegh-Guldberg (2006)
Phototrophic microendoliths bloom during coral “white syndrome” Coral Reefs 25:577-581
(pdf)

This is the one that appears to affect Acros, but assuming for the moment the mechanisms aren't unique, it's still an interesting read.

Sounds like the growth would have been more likely to be light-fueled and a response to the skeleton being exposed, vs being the cause per se.

Still looking for a more direct reference that's less specific to another coral...

 

[bios]

Exactly 100%
Endolithic algae

 

[bios]

Sorry but i'm only an italian PhD in byological sciences......eheh

 

[adestafi]

how does it get into ones tank or is it always present and lying dormant?

 

[bios]

Always Present, they have an important role in coral life .
They become dangerous when coral place under too much light and presence of phospates make cycle of the algae more fast then coral growth

I have a thread on this torch, but I came across this older thread after a lot of searching, and I wondered if any of the posters here could speak to my problem. I injured this torch accidentally with a gyre, that’s where the tentacle damage is from. I moved it to the sandbed and low flow. The damaged polyp actually seems to be expanding better today, after about a week, but I noted the stalk is getting clear and fuzzy. I attached photos, I don’t know if it’s a fungus, or the algae mentioned in this thread, or just a result of the trauma.



Any thoughts on it would be appreciated. Specifically, can I leave it to heal, or do I need to frag it and pull it so I do lose more corals? I’d love to be able to stop the decline. Like OP from a couple years back, the rest of my corals are doing well, including the other head of this torch.

Thanks!
