    Hi

    Have had this coral for about 1 month, expanded well and used to feed at night. It always used to shrink at times and then expand after a few hours. Now does not expand at all and have brown marks on its side.

    Other stuff around it.

    • My Clown Goby often "hosts" in it.
    • It fell about 2 cm onto the sand three weeks ago when I added a new coral. Expanded and feed fine after this incident.
    • Thought it looked like an alkalinity burn, but alkalinity has been stable forever.
    • All the other corals are healthy and expanding well.
    • It is downstream from a (Anthelia sp.?) softy, not touching. My Blasto is downstreem as well, but not effected. Blue waving hand (Anthelia sp.) ? - Marine Aquariums of South Africa
    • I have read that they can be sensitive to aluminium based phosphate media, have not used it for 10 days now.

    Is there anything I can do for it?

    Can not seam to upload photos at the moment, will try tomorrow again.

    is the coral recieving direct flow perhaps that its not enjoying? it would be advisable to check the phosphate as it is possible it could be part of the problem.

    with photos

    No direct flow, it is on a sheltered nook and used to expand about 2 to 3 times it current diameter in there.

    Will get the phosphate test, but got none of the normal phosphate present signs.

    Managed to upload photos

    Thanks

    Am worried about that, but the "injury" does not seam to relate to where the goby sits. He (how do you know?) is also gentle with the corals and only sit on top, does not do the clown fish thing of wiggling.

    Also taken up residence in the fox and cat's eye, they seam fine. I got a small birds nest for it, but way to small, may have to take the plunge and put a stag-horn in for it?

    Wondering if it is not related to the fall as it fell on the brown side, perhaps something got damaged inside?

    Hi

    Thought I would post an update.

    The coral looks much better, the brown bits has nearly "grown out" of the body, and it is inflating again and feeding. :)

    However is has gone from orange and green to pink and white, (one for @belindamotion) I am sure it has bleached? Is there anything I can do for it? Does corals mange to get their algae back inside an aquarium?

    Think I have narrowed it issue dow to the aluminium based phosphate media I am using. Have not used it for 10 days now, and the coral has not only stop deteriorating but also started recovering. Nothing else has changed in the tank.

    Now got to get a new phosphate media. :(

    Interesting Len, What brand of Po4 remover where you using?

    Have you checked your iodine levels?

    Hi

    I use Kent Phosphate Sponge, never had an issue with it, but a few sites warns of Scolymia Australis (assume it is) sensitivity towards aluminium phosphate removers. Kept them before and never had an issue, luck of the draw?

    Will switch to a resin based one and see.

    In terms of iodine level, no, I don't test for it, trying not to run the tank on such a detail level. I do 15% water changes a week with a good reef grade salt (Red Sea Pro), should take care of everything? I still however dose calcium and alkalinity.

    Will a coral recover it's symbiotic algae in an aquarium and is there anything to help/speed this up?

    I'm absolutely no expert authority at this kind of thing but here is my 2c:

    have you looked at RTN (rapid tissue necrosis) or brown jelly disease???

    here is a link to an article about it http://www.eurospirit.co.za/articles.asp?content=displayArt&art_id=65&mainCatID=2&subCatID=28&subCatDesc=Diseases

    This is one of the fastest spreading coral diseases in your tank. When you first spot it in your tank it normally is a little brown blotch of brown jelly like substance on the head of the Coral.
    Normally ignored by most people, until you start noticing that the flesh of the Coral has started disappearing around the jelly.
    At this stage if not caught you end up losing the coral within days of first seeing the Brown Jelly.
    It is most commonly seen in your LPS corals although it is also seen in SPS corals.
    If not treated promptly you can end up losing your entire tank of corals.


    although i'm pretty sure if it was then that coral would be dead already...

    Hu?


    Quite sure it is not. No jelly, the marks looks like burn/skid marks, nearly gone now, migrated to the end of the tissue, nearly like a blood pocket under a finger nail.

    The coral looks healthy now, not shrunken anymore, although it is not as much expanded as I have seen it before.

    My immediate impression was also brown jelly disease, but if the coral has lightened up and is still healthy, then i would say its expelling some of its zooanthelia while adjusting to conditions in the system.

    Did it come right on it's own again..? Or did you change that Phosphate Sponge you mentioned earlier...for a Newbie like me I'll like to know that.. if that happened to me, then I don't need to panic as it's propably expelling zooanthelia..

    I stopped using the Kent Phosphate Sponge, so not sure if it is related to that, or if it just adjusted to the MH light.

    Will not take a change for now and leave the aluminium base media out and switch to a synthetic resin. If it recover fully will put old type of media in and monitor closely to see if there is any effect. Probable safer to just not use it going forward.

    Think @Alan is right that the new system (probable the light levels) pushed it into an adjustment.

    Still not sure if a coral can get its zooanthelia back in a aquarium?

    Like the new colour scheme, but not sure if it will have enough zooanthelia to make food, think it will have to get some of the old green and orange colour back?

    They do, plenty corals/ nennies bleach and have a full recovery again.

    Thanks, will take a photo series of it, will be good to follow it and see how it happens and the speed of change.

    That coral is definitely bleaching(bleaching can be caused by numerous factors not limited too and including temp, light,water chemistry) something has stressed it, it is recommended that you try feed it directly to keep it strong while it trys to get it's zooxanthellae back.
