Please?... Bryozoan 10/27/07
Hi crew,
<Hi Deryck, Mich here.>
Love your hard work.
<On behalf of Bob and the crew, we thank you.>
Wondering if you might be able to identify the white bits growing
under some of my live rock?
<ScottF and I think it's a Bryozoan... though a sponge may also be a
possibility, but leaning more towards a Bryozoan.>
You guys/girls do a great job, thanks for any help you can provide!
<Thank you for your compliments they are indeed appreciated.
Sincerely Mich.>

Ye Ole
Trees... Bryozoans 7/10/07
Hello Crew,
<Hello Chris, Mich here.>
Just wanted to make sure none of the attached are a problem.
<Mmm, nope. No problems that I see.>
My feather duster has been emitting some stuff and I believe his
sons are the ones with a circle around them.
<Mmm, hard to tell/see, is possible, but perhaps a different
species...>
The other one that looks somewhat like a white tree has been up for
much debate on the forums. People
have told me they are Hydroids,
<No.>
algae,
<No.>
tree sponges,
<No.>
and my favorite, roots from the live rock.
<Heehee! No. It is my understanding that these are bryozoans. More

Thanks for the help and the job you do.

Bryozoans? - 09/06/06
Hi Folks,
<<Jan>>
As usual, thanks so much for the great service that you provide!!
You & your website have become an indispensable component in my
efforts to create a happy & balanced tank.
<<We're pleased you find the site useful>>
This stuff (see attached photo) has started growing in my tank,
which is a new tank (since May 2006). I have no idea what it is.
<<Mmm, the picture could be a bit closer...is difficult to
discern...>>
Can you help?
<<I have three guesses here Jan...this looks to be either a species
of hydroid, in which case you may want to take action to
remove...or, more likely I suspect, a species of Bryozoan, in which
case you can sit back and enjoy while they last...and my last guess
would be a species of sponge, also no reason for concern>>
Thanks,
Jan
<<Quite welcome. EricR>> <My guess is with Eric's. Likely Bryozoan
colonies. RMF> |

Cleaning Bryozoan skeletons 9/1/06
Hello WetWebMedia Crew,
<Adam>
Firstly, I've read through your articles on cleaning coral skeletons and have a
good idea of what to do but I still have a few questions. I recently collected
some dead calcareous Bryozoan skeletons from the beach which had been washed up
after a storm and I would like to clean them and use them as decoration in my
seahorse tank. They were definitely dead but there was still some organic
material from where they had been attached to seagrass rhizomes as well as dead
sponges, ascidians etc attached to them which I picked out with a pair of
tweezers.
<Good>
I soaked them for two days in clean fresh water, then boiled them and they are
now sitting on a wire rack in the sun. I was a worried about using bleach
because of their very porous nature and thought that it might be difficult to
ensure that all the bleach was completely washed away.
<Not so much an issue as the conjugate acid nature of bleaches... dissolving
these calcium carbonate based skeletons...>
They still smell very strongly of rotten sea life, will this go away after they
have been left to bleach in the sun?
<Possibly not for quite a long time...>
Also, some of the pieces are a very attractively coloured in a deep purple
colour, will the sun destroy this and if so would placing them under shade to
dry out be ok?
<Mmm, won't likely result in their being "cleaned">
Is there anything else I should do to make sure that it is safe to place in the
aquarium?
<I would "experiment" with dilute bleach (sodium hypochlorite) solution (either
that used for clothing/washing or the pool/spa industry), with different
dilutions... and rinse/soak for a day after exposure, change the water out (for
all new/fresh) and dose with a "dechlorinator" (or make your own...) a few
concentrations more than directions... let soak another day... This should do
it... though you can/could test for free chlorine still present...>
Here is a link to a photo of the type of thing am dealing with.

Photo use
Mr. Fenner,
<Judy (yes am that old to repeat your name a few more times, sigh>
The Shawnee County Conservation District respectfully requests permission to use
the Bryozoan, Iodictyum sp. photo from the Wet Web Media web site. We are
making a display of fossils with pictures of the actual animal when it was alive
(or something close with what they look like now.) May we please use the
attached photo?
<You may indeed. Please make it known if you folks want a different format,
resolution, re-scan. Thank you for your efforts. Bob Fenner>
Thank you,
Judy Boltman

Bryozoa Down the Drain
Hello,
I have a question I hope you can help me with. Bryozoa is fast becoming a
problem at water and wastewater treatment facilities across the USA. I know
there are some species that are freshwater only, but are you aware of any
studies or projects on the effects of the saltwater hobby and byproducts of us
cleaning our aquariums and flushing it down the drain?
<Mmm, interesting. Bryozoans, aschelminths period are a rarity in our
interest. Most all perish in the rigors of collection of the hard substrates
they colonize>
I work for a municipality in the metro Phoenix area and have witnessed an
outbreak of Bryozoa in the last 5 to 10 years that was not present before that.
Are there any species which might live in both fresh and salt water? I cannot
help but believe we may be a part of the problem.
Thank you,
A.J.
<Not as far as I'm aware. Wouldn't take much to find out. Here's my pitch on
doing literature searches: http://www.wetwebmedia.com/litsrchart.htm
Get thee to a large (college) library!
Bob Fenner>
Re: Bryozoa
Thanks for the response Bob. A group of wastewater professionals are meeting in
the Phoenix area next month to discuss Bryozoa and other treatment challenges
and we are hoping some of the legwork may already be done and available to us.
<Me too. Ah, reminds me of happy meetings with friends in organizations like
the "Aquatic Plant Management Society"... a great mix of
"old-timer" scientists, technicians, folks who "did" the
work... very enjoyable and great learning, sharing experiences>
Love your new book and really enjoyed meeting you and Anthony at our Desert
Marine Society meeting.
<Ahh! Now I remember!>
Can't wait until the others in the series come out. Any idea on the release
dates?
<Perhaps a year in-between each... Poor Anthony going over my poor initial
drafts, my poring through his verbose re-writes (he actually has an advanced
degree in literature!?)... then poor Christine doing the layouts!!! Sheesh,
amazing they get done at all. Thank you for asking. Bob Fenner>
Thanks,
A.J.
Bryozoan Algae?
Hi guys-
I have an opportunity to obtain a red Bryozoan. I have seen a photo of it
and it kind of looks like a Fauchea Sp. (Dark red macro algae). How would
you tell them apart?
<Upon close examination (just with your eyes, no scope) you will notice
that bryozoans are much more "stiff" than what you have shown
here... which looks like a red algae>
I was on your Bryozoan page but the photos don't show
up. It said I need a username and password from Tuskfish. wetwebfotos.com.
Attached are photos of it. I am buying it from someone from another state
and will not be able to actually see it in person. What should I ask in
order to confirm its identity? If it is a Bryozoan, what would you
recommend
regarding care - feeding, placement, water flow, etc.?
Thanx,
Tim

Bryozoan care
Also, what about the bryozoans? Do they need any special care? Are they
photosynthetic? Thanks!
