Tyree Neon Green Leather. I have attached photos, do you believe it is

I have looked at others online and notice slight variations in the polyps.
<Oh! There's all sorts of dissimilarity here to be expected; due to
recent experiences, conditions in locus>

<Doubtless; consciously and not>
Or was mine mis classified. I only have one not great picture of it when
it was open.

|Re: re: Tyree Leather Question
Ah my mistake. I know Steve Tyree has his name attached to many things in
this industry, but I thought Tyree green toadstool was a specific name for a
specific type of toadstool.
<Likely is; I don't know what is meant by "specific type"... Have seen
something similar listed as "ORA" "type">
In my reading over the past few days I have seen that leathers are usually
the aggressor, or at least the victor in chemical battles.
<Indeed they are; though all such life wars in various ways, degrees>
I thought this could be the issue so I did a water change yesterday and
I run activated carbon, but I can change it out just incase.
I have also read that toadstools will cover themselves with a mucus or waxy
like substance from time to time.
<Kind of a continuous behavior... build-up, and shedding>
There seems to be some debate as to what exactly this is a response to. I
didn't have much time to get my baseline observation of how mucus covered or
wax covered it appeared while it was open, so I don't know if this is one of
those cases. I had hoped it would come through in the pictures I sent, all I
have is my camera phone and it always wants to focus on the glass specks and
not the corals.
I introduced the toadstool by float method over approximately 25 minutes.
<... please read where you were referred to... this SOP is NOT useful for
I also introduced an Australian hammer coral over the same period. Both
corals are approximately 1 inch diameter. The toadstool being 1.5 to 2
inches tall. The hammer is doing great.

Tang ID / Coral ID & Advice 5/29/13
Hi Bob, Crew:
It's been a while since I've written, the last time you may recall a few
years back resulted in a Chloroquine Phosphate experiment in a 300
gallon display. I am hoping you can help me identify two species in a
tank I have recently adopted.
The first, the Tang appears to me to be a Zebrasoma species, I am
leaning toward veliferum; however, the tail markings are not consistent
with what I read on your site. Can you ID the species and tell if it is
a juvenile or adult?
<It is as you state; not quite an adult... grows to more than plate size
in the wild; turns dark>
Secondly, we have a problematic / unhealthy handful of what appear to be
I moved them toward the top of the tank nearer to the MH lighting and in
an area of increased flow about a week ago. Most were near the bottom
with weak flow prior. Can you help me ID the species or at least confirm
I am headed in the right direction?
<Don't need much flow; but do have other specific needs... is there
measurable NO3, HPO4 here?>
As you can see from the image,
the animal is not happy. The 125 gallon tank has been in place about 60
days with good, stable water parameters being 0 Ammonia, 0 Nitrite, No
traceable nitrates and S.G. of 1.025-26. 3-150 Watt MH (10,000k), 8
actinic florescent, with 12 hour photo period. I have targeted with
iodine, strontium, and calcium alternate with carbon in the sump /
refugium overflow chambers.
<... [Ca], [Mg], alkalinity? Other Cnidarian life present?>
I have included an overall view of the reef so you have a point of
reference. The (Sinularia) species in question is right of the Kenya
Tree near the top right of the image. It was moved from the far left,
bottom where the red mushrooms are now.
<These are likely winning out over the Alcyonaceans... see WWM re them
(compatibility FAQs) and allelopathy>
I do not believe the tank is overcrowded; although, there is a wide range
of SPS, LPS, and soft coral. Everything else appears happy, healthy.
Thank you for your input!
<Read on! Bob Fenner>
I bought this as a frag and was hoping you could help me identify it is it a
<Is an Alcyoniid>
surely it is not an sps as my nitrates are not always undetectable and I
don't think I could support sps? Thanks for the help.

Coral ID and attachment
Hi crew! A neighbor was getting rid of his tank and was going to
throw out this coral so I rescued it. It is in my QT and I am
wondering if you can ID it?

Also it was not attached to anything (no rock, shells, plugs) and
I am trying to get it to attach to this piece of live rock I
have. It has a nice crater like hole and the base of the coral
fit nicely into it. Assuming all goes well with the coral and it
lives how long will it take to attach to the rock?
<Several days to a few weeks>
<Welcome! Bob Fenner>
|Re: Coral ID and attachment 3/29/12
Hello Mr. Fenner! Thank you for the quick response. After
looking on WWM it appears to be a Sinularia. Thank you for the
ID...you guys are the best!
It would have taken me days of scouring the website to ID it. I
will now determine if it is something I can keep. Thanks

New Coral, ID 4/28/11
Hi WWM crew:
I am hoping you might be able to help me ID the coral in the

Alternate ID? for "UNKNOWN Hitchhiker Shroom
I saw this message from the dailies, "UNKNOWN Hitchhiker
Shroom 9/26/10" and would like to offer the guess of a small
Sinularia dura instead of an Actinodiscus/Discosoma. The oblong
white spots could be sclerites seen through the tissue, with the
prominences around the outer margin and on the surface being
polyps. Obviously a less blurry picture would help.

Coral I.D. (an Alcyoniid, me thinks) --
We are wondering if you could help us with a coral
<<I shall try>>
This was sold to us as broccoli coral -very easy care, filter
feeding and needing no light.
<<Mmm, I want to make clear here--'very easy care'
most always NEVER applies to marine organisms described as
'filter feeding and needing no light.' With very few
exceptions most all these type critters, and especially the
azooxanthellate corals, are very difficult to maintain for any
length of time--even by 'experienced' hobbyists. Most
starve, wither and die in weeks to months. But the good news is,
I don't think that is what you have here. I think what you
have is an Alcyoniid--perhaps a Sinularia or even a Cladiella
species (and looking 'unhappy' when this pic was taken).
Though it is hard to be certain from the pic and the physical
state of the specimen. Have a look around here and the associated
links and see what you think:
What little information we can find on these is very conflicting
and we can't seem to find a similar picture (especially in

We also read they may be toxic, is this the case?
<<Everything on the reef fights for survival/real
estate--these organisms have developed a very effective means of
'chemical warfare' to this end. But to be more direct,
yes, these organisms are toxic--and this 'toxicity' is

Thanks for all your help. You guys saved my Fungia (on hard substrate
until I read your site). It's doing great now, tentacles expand
quite fully almost 24/7.
Anyway, I have what appears to be a blue-gray Lobophytum. This guy is
one of those low, stalkless colonies with ridges/rumples, similar to
the large pic of the blue Lobophytum on your Alcyoniids page. Polyps
are white, small
(maybe 3 mm long? 1 mm diameter? I'm really bad at judging these
things), and retractile. However, the only problem is... it's not
soft! Is it just encrusting a lump of rock, or what? There's not
much thickness showing at
the edge of the colony, though. This is a frag, I believe, of one of
the rumples on a larger colony. From my reading on your site and
Borneman's book, I've figured out they're supposed to be
pretty stiff for soft corals, but this feels just like a stony coral!
There aren't any calyces, just little tiny pits that the polyps
retract into. What is this thing? I would kind of like to know before I
put it in my reef tank so I can know where to affix it. I can attach a
pic if necessary.

Green Sinularia? 10/28/09
< Hello >
About 8 months ago I purchased a "Green Sinularia" from
an online company.
Thing is, I'm not so sure it is what they said it was.
< It does appear to be a type a Sinularia or possibly
Paralemnalia sp.? >
Here are some pictures of it and was wondering if you could tell
me what it is and how to care for it.
< Standard reef conditions apply here. With lighting moderate
to high, and water flow moderate to strong. >
I have metal halide lighting
< 75W? 150? 250? >
and 2 x 600 gph power heads pointed forward from opposite corners
to create random current.
< Water flow could be part of your problem as well as
lighting. 2 x 600 gph in a 90 works out to roughly 13 X turnover
which I consider to be a little on the low side. Aim for closer
to 20X's turnover. >
From what I have read, Green Sinularia like to have good water
movement but not directly, however if I do not keep the power
head pointed at it, it kind of closes up. Since I have had it, it
has never really sat up right
like I have seen in pictures, but rather slumps downward. I have
a 90 gallon tank, with two hang-on Aqua-C Remora protein
skimmers, the power heads and a heater for equipment. While this
coral has grown since I've had it, it doesn't appear to
be in the most optimal conditions. Thank you so much for your

flow and slowly move it closer to your lighting. It could be as
simple as repositioning it.

Critter Identification -- 08/26/09
I have recently acquired a candy cane and have found what appears
to be a soft coral amongst the heads.
Can you have a look to see if you can ID it please as I have
looked through the site and a couple of books I managed to get my
hands on but cant find anything similar.
It measures approximately 10mm across and the polyps protrude
about 2-6mm (tips are feathery), the top is dome shaped and the
stalk looks like that of an aiptasia.
<It is hard to discern from the photo, but I would guess
family Alcyoniidae, and Genus Sarcophyton.>
Apologies for the quality of the photo but its the best i could

Coral ID 10/8/08 Hi all, <Hi Bryant, Mich
here.> This is my first post to the people at WWM, so in
advanced I give my thanks and say great job on the site. I enjoy
your site very much and it has helped me many times in the past
since I am rather new to being an aquarist :) <Glad you found
us!> I have had this coral for a couple months already.
<Best to know what you're getting for before assuming
care!> When I purchased it, the coral was tiny and about the
size of a golf ball. I bought it being told it was a toadstool
leather. <Is a Sarcophyton.> After a while of looking
around online I saw that some toadstool leathers have longer
tentacles than others. I just figured that mine had shorter ones
than the others and I did not pay it any mind. Recently, about a
week ago, the leather started sprouting little flowers, or
polyps. Hopefully you can make them out in the photo that is
attached. In the end I am curious to see what type of coral I
have and if it is looking healthy where it is. <It is looking
healthy.> After looking around I noticed that it needs
moderate light (at the moment it is at the bottom of my 55g reef
tank with 4, 54w T5's) I also read somewhere today that
leathers should not be placed near Zoanthids. If this is true
then I have to move it. <Sarcophytons exude many chemicals
that can inhibit the growth of many other corals.> Either way
I look forward to what you have to say, and once again I thank
you guys for the awesome job you are doing. <Welcome>

images let me know, I took this one with my phone and it is a
little blurry. <Is fine.>

|Leather Coral ID, Lobophytum -- 4/24/08 Hi,
<Hello Dave, Brenda here!> Could you please help identify a
coral I received yesterday? I bought a coral on a internet auction
and it arrived with an extra coral that I know nothing about, I
have attached a picture and I would be really grateful if you could
help me identify it and give me some advice as to where to place it
in my tank as I have quite a bit of live rock, t5 lighting and 3
powerheads. Also what food would I need to feed and does it need
target feeding. It appears to be a Lobophytum to me. This is
commonly called a devil's hand and/or finger leather coral. I
have not target fed this coral, I let it eat through the water

a little larger and turgid. Basically, I don't know how it
looks when the polyps are fully extended. So, knowing the species

the image what do you feel about its health and condition, how
large does it extend it polyps? Also, how much time does and
