At the risk of sounding like a complete ninny, I’ve made up a page of
pics (dialup friendly) to see if any of you have the time and patience
to identify some things that are growing on my live rock. I just can’t
seem to get my brain round all the stuff to learn with a saltwater setup
and so many pictures of things look like they could be this or could be
that but I’m never certain.
I should just accept what is in the tank and enjoy it I suppose but when
visitors come along and ask “what is that?” I’d really like to pretend
I’m knowledgable 🙂
Thanks in advance for any info,
Here’s the link

Sheesh – I am not 100% sure on any of them but would agree with most of your
assumptions – just ittle pieces of coral in the main. I also thought that
the shrimp was indeed a shrimp – maybe a banded one? But it doesnt move –
at all? So then it cant be…
Where did you get your rock?
Miskairal 2012-06-12 00:20:58
Ahh – you have made me feel a whole lot better, thankyou!!! I felt a
real dill asking this.
When we spotted that “shrimp” thing we both thought it was a baby coral
banded shrimp as I had only bought one a couple of weeks before we
noticed this thing. But no, it is always there and never seems to
mobilize. My shrimp is female (see I do know something) but I have only one.
The rock came from Cairns I was told so assume it came from the Great
Barrier Reef. I don’t know what normally comes in with live rock but I’m
very happy with this (certainly has got my husband interested). There’s
a crab as well that hides all day and so far doesn’t seem to be a
meanie. It’s missing a main front claw but otherwise gets around well at
night. It’s dark like the rock and looks as though it has fine sand
spilt on it. There is so much more I could ask about, so much stuff
growing but I chose the ones that are the most visible.

I think that #2 might be a Tunicate (Solitary Ascidian) but it could
also be a sponge. If you can touch it a sponge will usually feel gritty
while a tunicate will either feel slimy or leathery.
#3 looks a bit like a Colonial Ascidian (another type of tunicate) but
the picture needs better resolution.
#6 might be a shrimp molt. Do you have any shrimp in your tank? When
they molt the cast off shell looks almost exactly like the original
animal (but may be somewhat more transparent).
When I first looked at #7 I thought it was some sort of Tube Worm but
the transition from gray to green doesn’t seem right for that. Does it
retract when disturbed?
#8 could be a Hydroid or Gorgonian (Cnidarians, related to coral) but a
clearer picture is needed.

wow – where u get ur rocks ???

Just a tid bit about shrimp in general. They can be both sexes. As we
all know (at least I hope so) usually it takes two to tango……and a
shrimp will become what it has to be to procreate. I just buy any
shrimp, it matters not if they are readily visible with eggs or not.
In no time each and every shrimp in my tanks have carried eggs and
spawned……My oriignal shrimps, when I had only one in each tank,
never had any egg masses under them, and all it took was the
introduction of just one of the same species and next thing, both were
carrying eggs……Pretty neat watching them at night (only time I
have ever seen em release their babies) under a lunar light, more or
less setting there with their tails up, flicking off those babies…It
looks like a snow storm in the tank, then its like someone rang the
dinner bell as all the fish and other critters come out for a late
night snack of fresh shrimp. I have collected a few of them already
and put them in a mature tank without any predator critters, and they
did grow somewhat but they are just too touchy and time consuming to
rasie up to any size……makes you wonder how they manage in the wild
under the adverse conditions they encounter……

6) Shrimp Shed
7) Macro Algae (will sring up fast, and then usualy
disapears, gets eaten very fast by tangs)
8) A type of branching coraline algae. The blue tips are
the new growth, and the red is another algae growing on it.

Darn it – I can’t reach that far into my tank that is too deep for me 🙁
Googling while I write for these two – thanks for giving me something to google for.
This thing’s “feelers” move with what appears to be purpose although it
doesn’t actually move around. I’ve seen the moulted shell from my coral
banded shrimp and it’s a shell, this is less rigid and has been there
for weeks whereas the shrimp shell falls apart within 2 days. I will try
to get video that shows movement.
No it doesn’t retract and I’ve never seen anything coming from the top.
Wayne says it’s a macroalgae but the white doesn’t seem right for that either???
I only have an old fashioned camera that requires film 🙂
Photos taken on it have turned out crappy hence the video camera’s use.
Cameras are so hard to focus through water especially if you have to
take the pic on an angle.

Hmm, well I read that if the coral banded shrimp has blue/purple spots
it is a female and that is her ovaries. The female is also said to be
larger. Well mine has the spots and is huge. I’ve not seen eggs.

would love to know what it is myself, I’ve got a bunch of it on my rocks as

The white is where the green frons died back.
Steven 2012-06-12 08:27:28
how long did it take before your live rock became alive? I just bought some
last weekend and curious how many weeks it takes for it to come alive. I
bought Fuji if that makes any difference.
George patters 2012-06-12 08:27:35
Whatever #2 is, I’ve got one in my tank. It won’t stay that size for long,
though it does grow slowly.
Coffee is only a way of stealing time that should by rights belong to
your slightly older self.
Mark henry 2012-06-12 08:27:39
It’s not so much the origin of the rock as it is how it was handled
(collected, shipped, etc) and how you cure it.
I got 45# from my LFS that’s got nothing growing on it that I can see
(other than algae). On the other hand, I bought 45# from Drs Foster &
Smith recently that’s got loads of stuff growing and it’s only been in
the tank for about a week and a half.
Miskairal 2012-06-12 08:27:47
I guess where it comes from would make a difference to what grows on it
but not how much. My rock was about 2 months old when the photos were
taken but some of that stuff was there from the beginning, the corals,
just getting better looking and spreading. Fiji is not far from Oz on
the world scale of things so I’d assume it might end up with similar things.
It had been in the shop for about 5 days when I got it as I was unable
to get it as soon as it arrived. I dont’ know if there are direct
flights or truck routes from Cairns to Maroochydore where the shop is.
It was then packaged up at the shop in a styrene box with an inch or two
of water and lots of wet newspaper on it ready for the 3 hour trip home.
I handled it very gently and something stung me when I was putting it in
the tank. I tried to place it with the most colourful/lively looking
side up and I have not moved it or adjusted it since.
Good luck. I hope yours gets lots of interesting things like mine has as
it gives endless hours of interest.

The most popular rock comes from Fiji / Tonga / Indo PAcific
area…….Its not so much the stuff that is growoing externally on
the rock, that makes it live rock. A lot of stuff externally and
internally is going to die or get damaged during harvest, storage
prior to shipping, shipping, and storage by LFS, and the ride home
after buying it…..What may appear as barren rock can come alive
months and months later with things not seen at first. A lot of things
on the rock can come alive fairly early only to die off as the
parameters its in is not suitable for its needs, even though a tank
may be within accepted parameters……I had some live rock that wa
pretty plain, just had nice coloration of a deep maroonish red
coraline algae growing on it, and in a month it was literally covered
in some neat ricordea yuma shrooms………
Sponges etc do poorly even though rock may have been handled properly,
as spponges do not like being exposed to air for any amount of time
and are often quick to die off. I look at live rock as something that
is akin to a pig in a poke, as you never ever know what it may contain
or turn out to be like other than its shape……Anything else that
may or may not be on it is a bonus and a surprise in the making.

Thank you all for your answers. I have never had live rock before and the
LFS said it was a “must have” item for any saltwater aquarium.
Do I need to add anything special to the water? I bought a bottle of
essential elements for the tank and have just added it tonight.
