Unidentified something? 10/20/19
Attached is a better picture that you asked for to see if you can identify
what is circled. These are all through my 20 gal. marine tank.
<Likely a red algae species; see here:
and the linked files above. Bob Fenner>
White growths on LR
Hey Bob, I just finished cycling my 55g QT with LR. After almost 2 weeks all
readings are at 0. My wife noticed these little white fuzzy things
growing all over the rock. It kind of resembles lymph in some spots. What do
you think, worms? sponges? Is this normal?
<Small tubiculous worms; likely Serpulids>
Strange egg, SW, LR ID
I've recently set up a new marine tank and there are strange and wondrous things
coming out of the live rock still to this moment. It's been set up now for
around 2-3 months, was just wondering if you recognised this as it just appeared
recently, leading me to believe it's an egg or similar. Do I need concern as it
is next to a hole in which I saw a strange caterpillar
like worm emerging earlier?
By the way it's the small banana like thing in the middle
<Can't quite make this out.... need a better, cropped pic; but my guess is on
some sort/species of tubiculous (Sedentariate Polychaete) worm>
<And you, Bob Fenner>
Can you help me to identify this little tubular thing growing in my marine tank
please? It seems to have lots of teeth inside and has 2 openings.
<Mmm; yes; thanks to your sending a few pix. Am pretty sure these are Ascidians;
Sea Squirts. Not harmful; in fact indicative of good conditions and care on your
part. Bob Fenner>
Re: Tank thing
Oh, thanks Bob. I love my fishie family so that gives me peace of mind now.
Ta ta for now.
OK I've looked and looked
<Stop; can't tell what you're actually referring to in this pic... is it
the sort of white/grey spec.s in the approximate center? Re-shoot this,
crop it and send just a well-resolved image of what you're looking at>
and I can't I'd this. Its been there a few months and hasn't grown a
whole lot. But its one or more clear elongated bubbles.
The surface is very pearlescent. It doesn't seem to be an algae to me.
<Could be a poorly pigmented algae... like Dictyosphaeria:
Perhaps a couple of Ascidians, Poriferans... Need a better image. Bob

Its the bubbles coming out of the hole in the rock in the middle of the

OK I'll see what I can get.

Here are a few new pictures. I hope this helps. By the way, this is all the
re: Unknown bubble. 2/26/15
Sorry. That's the best I can do. All I have is my 8mp phone camera.
<.... ONE well-resolved image, please. BORROW a camera. B>
I found something at the LFS in which they don't know what it is. They
believe it is some type of algae and it seems to grow fast.. Here is the
best picture i can give you.. Under the actinic lights its bright red.
Thank you again
<Mmm; appears to be a Rhodophyte... maybe a Halymenia species. I'd
search through Algaebase.org re.
Coral id help <...?>
Hey iam jus wondering if u would be able to see if u know what these 2
corals are thks
<... the first is a Porites... the second... Neomeris, a green algae.

Identification; harm? 12/15/14
What in the world is this stuff!? I think it has a pulse! Looks like a
whole bunch of tiny little eggs strewn together? Is it safe??
<Mmm; do you have a microscope handy? One w/ a USB hook up so you can
make some pix? My first and best guess is that this is some type of
Sponge (Poriferan); see WWM re the many similar IDs there. My second et
al. guesses are on mixes of algae and other Moneran, Protistans. To your
last question; likely so; though I'd likely vacuum most out during water
changes/regular maintenance; on general principles (not wanting
metabolites from the mass to mal-affect the biol-utility of the system).
Merry Christmas! - at the end of Nov I sent you some microscope pictures
of what you thought was sponge period but the resolution/quality was not
good enough. I have managed to get a higher spec USB microscope and
attach a picture - are you able to advise from this?
<... this pic; looks like a non-magnified image of mostly
BGA/Cyanobacteria... does it "feel slimy" to the touch?>
Growing rapidly in my tank and has become the new "Pest" having
controlled previous algae issues - how can I remove/reduce? Many thanks
<See WWM re BGA... do you need help using the search tool or indices?
