What is this?      6/3/16
I purchased this from my LPS about 6 months ago. I though it was a sponge, but it isn't. It seems to be growing rapidly and if I put it somewhere it doesn't like to be it can expand to move itself from the crevice. Any idea what it is....does it pose any threat to my saltwater tank (given off toxins, etc.). Your expertise is appreciated.
<?! This is a soft coral... a Nephtheid.... See WWM re... your system must be optimized and stable... for it to be doing this well. Bob Fenner>

Dendronephthya or Stereonephthya?
Dear Crew,
I've had a few of these corals for a while and have been having a very hard
time distinguishing between (at this size at least) Dendronephthya and Stereonephthya. I turned the lights on three hours after lights off to take this picture and they seem to be quite expanded. Are you aware of how to differentiate between the two genii and under which genus these fall under?
<My guess is the latter... from gross appearance>
Thankful as always for you help,
Sam Sutton
PS: Sorry if the file is a bit large, I am unsure of how to compress it
<Easy enough to search, use software that's likely on your computer already, or available free on/via the Net. Bob Fenner>

Neph ID 8/18/10
What type of coral is this peach colored stuff in the center? Looked to me like Scleronephthya only closed up. What do you think?
<You are probably right. Cheers, Marco.>

Re: Sea Slug ID: Likely Tritoniid Nudibranch, now Nephtheid - 5/24/10
Hi Lynn,
<Hi Nick!>
Thank you so much (I must also say WWM is brilliant)
<You're very welcome and thank you!>
It is indeed a soft coral, and the only coral I currently have - I can't remember its name now, could it be a Nephthea?
<Well, coral ID's aren't exactly my forte, but that does indeed look like something in the family Nephtheidae (order: Alcyonacea). Unfortunately, Tritoniids love to eat Alcyonaceans.>
There are some photos attached if that helps.
<It certainly does, thank you.>
I wasn't sure I was able to keep corals alive in my tank, now it looks like they might have just been eating them.
<Likely so>
I think you are right, it may have been the white vs. orange that made me miss the pictures.
<I can certainly understand. That particular species varies from white, to orange to a reddish orange but if you don't know that, you can easily dismiss it as a candidate. I've done the same thing myself a time or twenty!>
On closer inspection, it indeed looks like they have laid eggs all over the base of the coral,
<Yikes! I'd hoped that wasn't what I was seeing in one of the previous photos.>
I thought about using a freshwater dip, but I believe I read on your site that the freshwater dip could kill the coral,
<Yep, corals do not like freshwater dips.>
..so will probably go with gently scrubbing them off in a bucket of tank water.
<Sounds good. Definitely get rid of those eggs and keep an eye out for more Nudi's.>
<Take care>

Help with proper coral name please 2/2/2010
Hi, I was wondering if you could help me find the proper name for this poor unhappy coral? My LFS told me it was a flower tree coral. I would like to find out more about it since it is now very unhappy.
Thank you
Tina & Nigel
<Umm, you're not going to be any happier... Please see here re this Nephtheid: http://wetwebmedia.com/nephtheids.htm
Not easily kept. I'd return this specimen pronto. Bob Fenner>

Coral ID Please 10/10/09
Hi crew!

<You're welcome.>
Without further ado, onto my questions:
I recently received this frag and have been having trouble with the ID .(pic attached)
The two possibilities that I think it could be are either Lemnalia or Dendronephthya.
Please could you provide me with a positive ID on it?
What are the chances of this surviving in my tank if it is Dendronephthya

Tree Coral identification 9/10/09
Hello again WWM crew.
I have another coral I need identified.
<See here: http://wetwebmedia.com/nephtheids.htm>
I`m finding this one deceptively hard to identify.
I've tried having forums identify this before and everyone says its simply a Kenya tree and that
"everything" tends to look like a Kenya tree.
I am Reasonably Certain this is not what they are saying it is.
At best it is some other type of Capnella.
<Is this genus>
As you can see from the image its coloration is quite different, having a Whitish pink coloration with
a strong green hue Present in the stolon.
The polyps are much smaller and much more densely arranged then my two regular Kenyas.
The polyps also seem restricted exclusively to branches where as the Kenya trees seem to have random polyps everywhere except at the base.
This corals polyps also don`t extend as far out, forming a cup shape with the tentacles.
The polyp coloration has darkened considerably since I acquired it "it was originally entirely white"
The tentacles now have a strong brown coloration while the bodies of the polyps remain the same color as the stolon.
I am uncertain how useful this information will be in identifying this coral but I thought I had better write down as much as I can about it.
<Color means little here. Bob Fenner>

Hopefully Simple Soft Coral ID 6/11/09
Good Afternoon Crew;
<Hello Hans>
Thank you again for answering my lighting question a couple of days ago regarding my PC lights, I feel much better about my tank setup as a result.
<You're welcome.>
I was hoping you could help me nail down the ID of a soft coral I recently picked up, with photo attached. I believe it is a form of Neospongodes, which I feel comfortable in keeping right now. However, I just really want to make sure it's not Dendronephthya or some other near-impossible to keep species which would necessitate returning it to the store. It is currently mounted on a smallish conch shell of some sort, so I do plan on cutting up the shell to separate it from the polyps that came along for the ride. I can't imagine both species doing well long term in such close quarters.
<It appears to be a Kenya Tree Coral, family Nephtheidae, genus Dendronephthya, and likely a Roxasia. Unfortunately, this is a most difficult coral to care for and most will wither away in a matter of weeks.
This coral does not derive its energy from the byproducts of photosynthesis but feeds almost exclusively on phytoplankton, and requires both a steady supply of phytoplankton and sufficient flow to carry the food to its polyps. Do look/read here.
Most Appreciative;
<You're welcome. James (Salty Dog)>

Capnella. RMF

Re Hopefully Simple Soft Coral ID 6/13/09
Well, that's a bummer of a piece of news. I really had hoped I picked something different and within my means to care for.
<Is why it's best to research before buying.>
Is there anything more specific that I can look at to confirm that it is a Roxasia, before I haul it back to the store?
Would there be anything in the behavior to look for? Perhaps a closer photo of the polyps could help?
<Have you looked here? http://www.wetwebmedia.com/nephtheids.htm
Googling will lead you to photos, etc. James (Salty Dog)>
