Bubbles at base of mushroom coral
What an awesome amount of information you have here! I tried
searching and found only one response from a number of years ago
but it didn't seem to really tell what/why. This isn't so
much a problem, but more of a query. I received this mushroom
nearly a month ago and after taking a while to 'grab' on
the frag plug I put it on my mushroom wall. At some point I
noticed that at night the foot would swell out with these bubbles
around the base. It seems to get happier by the day opening up
bigger and bigger, but at night it recedes and the bubbles get
Any explanation of what this is or why it happens?
<Usually something in the way of incompatibility... another
Cnidarian species... or summat w/ water quality...>
Tank has been up for 4 months, parameters:
System volume: 150g across a 75g DT, 2 refugiums, and a sump,
system has about 200lbs of live rock and lots of macro algae
Temps: 71-73F (will be a seahorse devoted system)
<Mmm, a bit low>
<Uh, need some NO3... whatever means you're employing to
keep this at 0.0 ppm may be at root here>
(those are both a little low, but stable)

Shrooms. They are just not growing - 10/06/2009
<Hey Thomas! JustinN here!>
I have read and read over the site... over and over again. I love it! I
looked through all your articles and FAQ on Mushrooms, Corallimorphs
and Cnidarians. Good info...
BUT! I can't figure out what's going on with my Shrooms. They
are just not growing.
I have had them in the tank for almost 2 years. I currently have them
placed up high, down low, in shade, in full light trying to figure out
what they like best. None of them seem to be responding super well.
<Are you/have you tried target feeding them? All the Corallimorphs
I've had in my care over the years liked something nice and meaty
fed to them periodically -- one of my mushrooms has even decided it
likes New Life Spectrum pellets!>
My question is could there possibly be a nitrogen
<Deficiency? Your goal is to eliminate the components of the
Nitrogen cycle, so not likely.>
My nitrates always test undetectable.
<This is a good thing>
I can't seem to figure out why the "easiest" inverts are
giving me the most trouble. Here's the scoop on my set-up:
The tank has been running over five years, and has been a "reef
tank" for over two. I have always used RO/DI water and Seachem
<A quality product>
Pulsing xenia - doing so well that I almost regret adding it
<They are a bit like a mesmerizing weed, aren't they! :)>
Green star polyps - doing super well
Halimeda - just popped up one day, now it's growing everywhere
<And this is why I love live rock ;)>
Assorted Zoas - doing okay for being under PC's
Red, green striped, green spotted and blue mushrooms
Hammer coral - not growing much, but looks good
One Royal Gramma
Two Ocellaris clowns
Two Yellowtail damsels
One hermit crab
<Sustainability of the Mandarin is questionable -- these consummate
'pod consumers will clean your tank out in no time.>
70 gallon show tank, 60"x22"x12"
100 lbs Fiji and Caribbean live rock
80 lbs live sand
322 watt PC's with half actinic (420nm) and half daylight
replace bulbs annually
<Sounds good to here>

Three 150 GPH powerheads
Prizm pro Delux skimmer
<Your BioWheels may be creating/generating more nitrates/nitrites
than you know, as this is part of their design -- they're not
typically optimal in a reef setup. The skimmer is definitely undersized
-- Prizm's are really only 'effective' for about a 40
gallon or so total volume -- and even then, their efficacy is
Alk 8-9 dKH

<Sounds like it should be -- are you certain of these
nitrate/nitrite readings? What brand test kits are you using?>
12 gallon (18%) water change every 2 weeks
Top off with RO/DI water, with Seachem reef builder/calcium (on
separate days) as needed.
<Is the Reef Builder/calc just added arbitrarily, or based off of a
system that involves measurements?>
Is something standing out to you here? It seems normal to me... but
then again I'm not the pro...
Thanks for your help!
<For the most part, I would agree, this sounds very normal
configuration-wise -- my main thoughts are your bio-media filtration
(BioWheel, filter floss in your Proquatics HOT), and a lack of direct
feeding. Try giving the mushrooms a nice blast of Mysis shrimp with a
small pipette, this may be the missing key here. Good luck!
Re: Corallimorph Growth - 10/06/2009 <I remembered, Bob!
<Hey again Thomas! JustinN again! I cleaned up your responses a bit
here, to conform to the standards.. I hope you don't mind!>
I use Phytoplex, coral excel, and Zooplex, each individually about
twice a week
<All decent products, but not what your Corallimorphs are after.
Move to some mysis and/or a copepod-based food, such as Cyclop-Eeze.
These are going to benefit your mushrooms greatly, you should notice a
He's (the mandarin) been in there almost two years, he's always
nice 'n fat too...
<Well, this is excellent -- definitely not the typical end result.
Good hands on your part :)>
Should I upgrade to a Remora w/ a MJ1200?
<Would be a worthy upgrade -- definitely far more effective than the
Prism.. Do keep in mind, I wouldn't call this essential, since your
tank is clearly quite stable -- a 2 year run for a Mandarin is not
I'm using Aquarium Pharmaceuticals test kits
<I would recommend trying some of the higher quality brands, such as
Salifert -- might get differing results from current.>
I measure to maintain calc @450ppm, KH @8-9dKH which typically
maintains my pH @8.3
<Sounds good here -- I've just known too many people who come up
with some arbitrary number, and add this arbitrary number blindly on a
not always a good plan :)>
I'll try feeding mysis... (keeping the fish from getting them will
be the trick!)
<The fish will definitely be getting some -- my usual technique is
to feed the fish sporadically while I feed the corals. A small pipette
helps immensely with this, allows you to slowly provide the meaty food
mushroom. After a few feedings, they'll get more used to it, and
will typically start wrapping up a bit as soon as you bring the pipette
near -- it gets easier with time. Good luck! -JustinN>
Giant Cup Mushroom Losing Flesh 2/27/08 Hi Crew,
<Hi Mohamed> I am asking this question for a friend. She has a
giant cup for 4 years with on <going> problems. The water quality
is within range, no high levels of nitrate, nitrite, etc. but she
unsure of iodine levels and water changes are done regularly.
<Wouldn't worry too much about iodine levels, regular water
changes with a good reef salt should provide all that is necessary.
I've supplemented with iodine (Lugo's solution) in the past and
have not seen any benefit in it's use.> The giant cup does not
open up completely and if you wave your hand next to the GC its flesh
is peeling. Could a low level of iodine cause this or what could cause
this, a disease? <The Giant Cup Mushroom is a meat eater and I'm
wondering if it has been fed small pieces of shrimp etc. A healthy
specimen should close/wrap completely around the food. As far as
lighting, they do require medium intensity light to survive. You did
not mention lighting being used.> Thanks, <You're welcome.

- Mushrooms Fed and then Died
6/15/06 - Sorry, I have never posted before and I REALLY hope I am
doing this correctly. <No worries.> I bought a BEAUTIFUL rock of
chromes some months ago. It was healthy and happy, very open and
thriving. It is in the tank next to a rock heavy with green hairy
mushrooms. They have both been doing fine, actually the green ones are
about a year old and have done really well. A few days ago my husband
felt the need to target feed them because he was CONVINCED it was the
right thing to do for them since I have NEVER EVER fed them. I run a
fuge and feed the fish everyday and they always seem to catch a little
of their food every once and a while. They always looked happy so I
figured, if it isn't broke DON'T fix it. He is an engineer so
he ALWAYS knows a better way... Anyway, he fed them Cyclop-eeze mixed
with tank water through a tube feeder direct in the middle of each
mushroom. They immediately closed up like they were eating so he
thought it was what they needed and did it again the following day.
They reacted the same way as the day before. Then when wok up on
morning three, both rocks inhabitants seemed to start just melting
away. Now one rock is completely empty and the green ones are not far
behind... Is this happening because he OVERFED them? <It certainly
sounds that way but it's difficult to know with absolute certainty.
That being said, it would be unusual for food alone to kill a mushroom.
Perhaps cross contamination from the feeder device.> If they were
doing fine with what I was doing, should I just continue to care for
mushrooms in this fashion??? <Mushrooms need little direct attention
and often do better with none at all... so, stick with your methodology
and tell your husband to keep his feeder to himself.> Thanks
Danielle <Cheers, J -- >
My mushroom shriveled up Hello, 2 weeks ago I purchased a
what the LFS store calls a super mushroom. <"What's in a
name?"> In the store it was nice and big and all opened up.
After several days in my tank, I noticed that it has all shriveled up
and white stringy tentacle are oozing out of its stomach. <Ooops>
I have never seen this shroom bloom like I have seen it in the LFS. One
night I noticed my camel back shrimp picking on it so I went ahead and
removed all of my camel back shrimp and return them to my LFS. I hoped
that now that my shrimps are gone my shroom will not be stressed as
much and will start to open up. I also have my shroom on the top level
on my rocks. I also have a small mushroom that shriveled up and turned
purple on me. What could be wrong? My ammonia, nitrite and nitrate are
what they are supposed to be. Here are my params: 46G Bowfront 2
- 97 W. PC lighting Rena XP 2 Filter Fluval 404 Filter Remora Skimmer
Temp - 79 -- 80 I read that Iodine is essential for shroom.. I used the
Reef Solution once a week and feed my corals Marine Snow once a week.
<The last is worthless> Should I be adding more Iodine?
<How much do your tests show is present?> Please help <Please

Shroom Health Thanks for the recommendation on lowering
salinity, it seems to be deterring the ick that wrought this tank weeks
ago. I do have a question though, IYO, I have a 55 that was reef until
I had to stick a huge queen in it (i.e. ick in other tank, Maroxy for
sec. infect, killed bacteria), anyway water quality seems fine (trates
about 20ppm), but I put a compact lighting system on at the same time.
I have two corals (they are protected from the queen by crating,
mushrooms, and polyps), the polyps are bountiful, but the Shrooms seem
pissed about something, they are all shriveled up, but not detached. Is
it the lighting? They are no on the bottom of the tank. Other than
RedOx (I don't currently test for) there are no other causes. I add
a supplement 2 a week, from what I understand, they don't require
any outside feeding. Thanks tom >> Something is awry with the
mushrooms... maybe an interaction (chemical or physical) with other
stinging-celled life in the tank... maybe the lighting, perhaps the
supplements... but about all you can do is move the colonies from other
life forms, and hope for the best... You are correct in that they
don't require specific feeding in an otherwise "fed"
system... Bob Fenner
