Any chance you can post pics of the affected area? I don't think this is bacterial.

Cheers
Steve

Hi Steve,
Not at the moment no because I pulled the affected bit off. The area around it is covered by extended tentacles so i can't see the affected area properly - even at night because its not been receeding as it should since I pulled that bit off.
I'll post a pic if I get a chance.

Do you know of anything you can add to promote regrowth of a receeded area on euphillia corals?
Any help is greatly appreciated.
Thanks
Liz

You can very gentley "fan" the crown with your hand. It should retract enough to get a photo.

Depends on if it's a typical specimen or "parancora" (branching). Branching species of Euphyllia do not typically "rebound" well. If the flesh is only slight detached, it should recover though. Liquid marine vitamin C will help immensely as will feedings. Just be wary of dosage as it can affect pH. If the crown has done a complete polyp bailout, then it won't regrow.

Also be sure if it is just receded some that it's in a subdued light setting and med-low water flow where it can recover with less stress. Excessive amounts of either will cause further receding

Cheers
Steve

Hello again,

It has taken me until now to get a decent photo of the affected area. The first photo is from today and the second is from yesterday.

It just looks though parts have died (nothing else visibly wrong with it). All fish, inverts and other corals are fine.

Hope you can help.

Thanks

If you mean the area I've circled below, it's receded. Either it had been infected or irritated causing the flesh to necros. Judging by the surrounding rock, placement could be the biggest issue. You need to be quite careful that nothing of the corals fleshy crown is against a hard surface. It tends to irritate the coral and cause this kind of recesion as will heavy water flow or coral warfare.

Place the coral somewhere it can stand straight up so only the base is supported and the upper areas are free of anything touching it. Also keep an eye on the cleaner shrimp. Although only doing it's job, they can quickly make a small problem much worse as they clean away the decaying or damaged flesh.

Cheers
Steve

Hi Steve,
The bit I have the problem with is the pale almost white part between the bare receeded part and the still healthy part. The very bottom of the bit you have circled.
The fleshy part of the coral isn't touching anything but I will reconsider it's position if this may be irritating it.

The cleaner shrimp hate it and won't go near it but I have a tiny bristle worm living in the receeded bare area which I have been trying to get rid of for over a week. Little ******* knows I'm after him.

Thanks for your help. I am considering taking it back for the LFS where I bought it as it's definanttely not a happy coral.
best wishes
Liz

Thanks the bit. It doesn't appear to have any other symptoms - just seems to be dying. I've had it for a month (the bare bit was bare all along - it hasn't receeded much more than a few polyps (maybe 5 - inc the ones you can see here)

Thanks
Liz

The only thing I can suggest is possible repositioning and being sure the water specs are all good including the chemistry. Although it does not seem to be necrosing (which suggests predation), some liquid vitamin added directly to the tank might help. Just be sure to remove any carbon/resin products for a few hours.

It could be a predator other than the worm you saw but the easiest means of removing that guy is placing a small piece of food in a little square of nylon stalking and tieing it. Then just place it near the coral but away from the "sick" spot. The worm will get ensnarled in the nylon and can then be removed. As always checking after lights out for nocturnal pests is advisable. Be especially watchful for nudibrancs, odd worms and snails.

Cheers
Steve

Thank you Steve for all your help you have been brillinat (and patient).
I'll follow your advice - it makes a lot of sense.

(My Dad is busy laughing at the nylon stalking - he already thinks I'm turning into a Gnome what with the little stall I sit on to watch the tank. One day I'll persuade him to move the sofa!)

Thanks again. I'll let you know what happens.
Best wishes
Liz
