Reef tank - White, waxy, reticular "growth"
between rocks - what is it? 04/17/2006 You are a
gold mine of information for which I am most grateful so I
apologize in advance if you've already answered this question
and I failed to find your answer. <We'll see...> I have a
year-old, well lit, 75 gal reef tank with a few generally hardy and
reef-safe fish, corals, and inverts. My problems have been limited
to a few fish disappearing completely within a couple of days of
introduction, early demise of two open brain corals (several months
apart), and majano anemones that double in number about every 2-3
months <Don't we wish we could clip those genes onto the
cash in our accounts!> which has now become a problem.
Temperature is 80 and chemistry is within acceptable limits accept
the salinity has crept up but which should be easier to control now
that I've bought and calibrated a refractometer. <A nice
tool> My question is, what is the white, waxy material (center
of the attached photo) that forms something of a web between and on
my live rock. It's been there for weeks and seems to be growing
slowly. <Nice pic, apparently tank en toto... This
is a type of sponge, no worries> I'm also curious about the
patch of tiny brown polyps(?) with green tips near the center of
the left edge of the photo. I saw what seems to be a larger version
of the same thing in the Georgia Aquarium's reef tank but there
was no label. (Sorry about the fuzzy photo but the stuff IS fuzzy.)
<Mmm... look like some sort of small zoanthid sp.> And, as
long as you are looking at the photo, those ARE majano anemones in
the upper left corner, aren't they? <Yes... I think so as
well. Bob Thanks,

| Unidentified tagalong to LR...
- 04/05/2006 Howdy
from Texas! <Backatcha from Southern Cal.> I'm in the
process of curing 15lbs of LR purchased from a LFS in a new 29gal
tank (my first foray into the marine art). Everything seems to be
going as planned, but in the process of my cleaning routine of
removing dead algae, this 'egg' fell off. I'm leaving
it be for now, as there's nothing in the tank BUT the curing
live rock, however I'm very curious as to what to expect. I
couldn't seem to get a very good picture, so to supplement the
image, its kind of an off-red translucent with darker red stripes,
shaped similarly to the body of an emerald crab. There is an air
bubble of some sort inside of it, leading me to believe some sort
of embryo. However, I am of course no expert, so I turn to those
who are. Regardless of identification, is this something I should
allow to remain? Can I assume it will be something beneficial, or
might that be a mistake? Thanks in advance! Justin Norman <Looks
like a bit of shell (Mollusk) to me. I'd also leave it be...
Enjoy! Bob Fenner> |

Critter ID...Limpets - 04/01/06 Hello!
<<Howdy>> I need help ID'ing these
critters. There has been an 'outbreak' of these
critters. I say that because there are quite a few of
them. I've look through WWM but am unable to ID
them. My guess is a sort of snail. <<Looks to be a
Limpet (a mollusk)...possibly P. vulgata>> Some are on the
glass, but most are on the live rock. Should I worry
that they'll be to many? <<Probably not, these are
considered to be primarily algae grazers. Just keep an
eye on them but they'll likely be fine.>> If they are
snails I hope not. I wouldn't mind having a big
janitorial crew. I did have a pair of Turbo snails. Key
word 'have'. Thanks,
Stan
<<Regards, EricR>> |

| Live Rock/Hitchhiker 3/30/06 Do you know by any
chance what can it be - white, slightly translucent, cotton ball
size, web-looking interweaved filaments with several extended tubes
(image attached). Something like tunicate or sponge; should I leave
it or remove it? <Neat looking. I'd
leave it. Appears to be some type of sponge.> Thank
you! <You're welcome. James (Salty
Dog)> Elena. |

Crustacean Conundrum - 03/22/2006 Hello Wet Web,
<Hi Mike.> I've got another question for ya! I
just purchased about 30lbs of live rock from an established aquarium. I
transported it under water over to my house in about 7hrs. I put the
rock (Fiji, Marshall, Tonga) in my tank and was wondering about a
couple of little critters running around. I used a flash light at night
to see what nocturnal animals would come out and I saw really really
small critters (less than a cm, maybe the size of a pen head) running
around all over the place. When I flashed the light on them, they seem
to glow a little. Do you have any idea what these are? They seem to run
around really fast and there are a ton of them. Could they be copepods?
<Could be, most likely seeing a mix of copepods and amphipods.>
Could this be mantis shrimp offspring? <I don't believe so.>
I also saw a couple of other critters that looked like they might be
mantis but I'm not sure. I've looked at a couple photos but
can't really tell if it's the same thing in my tank. They look
like shrimp, they are about a cm long and they are kind of clear or
white. I saw maybe 4 of them in my tank. About how big do they get?
<These would be the amphipods. Not much larger than you are
seeing.> Will they reproduce in my tank? <Yes.> Is this
something to really worry about? <Nope.> Will a Green or Spotted
Mandarin Dragonet eat these? <Like you wouldn't believe!> Any
help is greatly appreciated. Thanks for all the great info on this
website. <Start here http://www.wetwebmedia.com/pericaridanfaqs.htm
and explore the related links/articles for more on
microcrustaceans.> Mike <Welcome to crazy critter country! -

Live Rock/Hitchhiker 3/20/06 Hi
Bob, <James today> Thanks again for the
wonderful site! <You're welcome.> I
currently have a 75 gallon tank with Live Rock, Live Sand, 4
Snails, 1 Emerald Crab and 2 Hermit Crabs. I have a
slight problem with Aiptasia, and my local dealers haven't
had Peppermints in stock yet, and I want to eradicate that before
I add corals. So I'm just basically growing
coralline algae right now on my rock, and watching the little tag
along critters. Anyways, I snapped a photo of a critter I have in
the tank. I have dozens of these in the tank and I
can't find similar photos on your site (might just be looking
in the wrong place), so I figured I'd snag a picture for
you. I just want to make sure they're not harmful
before I add fish. The don't have heads protruding
like the Isopod Images you have on your site. If you
could help me identify this, and let me know if I should worry,
let me know. The largest of these is about
¼ inch long right now. <A Chiton of some
type, will cause no harm. James (Salty Dog)>

Crazy Live Rock Critter - 03/17/2006 First off, I cannot
begin to stress how helpful the site has been to me. <Very glad to
hear it.> I have a 200 gallon system setup. It has between
150-175lbs of live rock. The other night I turned on the light and saw
something odd. <Happened to me once and though I can't get him
to admit it, I'm sure my dog knows I saw him ;)> It looked like
a long piece of string roughly 10-12 inches long. It was a red/pinkish
color. First thought was that it was an extra long piece of bi-product.
A minute later it retracted back into a small crevice in a piece of
rock. <Some sort of worm no doubt.> I caught a quick glimpse of
the end of it and it seemed to have a fork shape end to it, similar to
what a starfish moves with. Sorry I can't think of what that is
called. <The tube feet?> So have you ever seen/heard
of this? <Yes. I've seen many similar things in my tank.> I
have had this setup for over a year and have never seen it until now.
<A good indication that things are coming along nicely. -
Josh>
