Re: ID Help: Foraminiferan, Likely Marginopora sp. - 4/21/08
<Hi Paul>
Yep, that's a positive ID, "Marginopora vertebralis"
<Yay!>
..and the smallest I've seen was approximately 1/8". The one in the picture measures 5/16" diameter.
Thank you very much for your help.
<It was a pleasure. Take care, -Lynn>

Re: Polyps of some sort in my sump?
Wonderful! Thanks for the ID. Looks like my nutrient levels have risen to support these. I'll check to see if my skimmer pump filter is clogged since I have noticed reduced skimmate the past week - just before these little guys arrived.
<Well, in many ways, they are little filters themselves. ;-) They usually come in boom and bust cycles. People seem to get them in droves all of a sudden, but then they don't last.>

<Best,

Hello wonderful people! Lotsa pix, disparate organisms, reading to do  03/11/2008
HI! I want to start by saying that I have read a large amount of your site content - about worms & feather dusters & live rock & coral & algae - I'm sure the questions I am asking are somewhere on your site, but I cant find the answers.. (and I have been saving my questions for about 3 weeks - to ask them all at once!) I put the pictures on a webpage - thinking perhaps it would be easier to see them in a separate browser, instead of downloading an email attachment? IF BY SOME CHANCE there are any pictures that you want to keep or use, feel free.. and if you would rather me send the pictures in email, i will..

<Ahh, very nice!>
OK, picture #1 shows 2 things i am concerned about. On the left is a rock with what looks like a rust spot?
<I agree... this does look ferrous... I would not be overly concerned if this is the only such rusty area... not likely very toxic here>
This along with a couple of other things has me concerned that some of the rock (bought at LFS) is straight out of the ocean..
<?>
On the right is something that resembles (to me) things i read about worms - or maybe coral? The pink growths on the rock..
<Sponge material... no worries...>
#2 shows this odd crevice in a rock - it looks very flat & smooth - and has white spots/deposits on it.. my overactive imagination feels like maybe divers salvaged "something" out of the rock.. or that maybe there still is metal in there?
<Looks like a bivalve to me... see the Net, pix with the name "Arca">
#3 this is from a small(10g) tank that i originally set up for a refugium, but there is no shared water source between them, so for now it is just a separate tank, that i put water from the bigger one into when i do water changes. All that is in it are 3 snails, 1 crab, and some small pieces of macro algae & live rock... up until a week ago I had a powerhead with sponge filter in there - and have taken that out and put just bubbles in.. trying to raise copepods and amphipods in there.. It is being overrun with this stuff that starts as 3a, and then ends up like 3b.. is this OK stuff? I cant even tell if it is algae or another type of aiptasia??(and my big tank is getting infested already with this pest)???
<Mmm, maybe a Hydroid, perhaps algal...>
#4 shows something - perhaps a barnacle? there are some others i see in a hole on just this one rock, but i never see them stick out?
<I see some algae...>
#5 I'm concerned with my feather duster, his "feathers" have gotten thin as they are sticking out further than ever from the tube. I think it looks like he has a double head. Purchased him 6 weeks ago & for the first week he only stuck out of the tube about 1/2 -3/4 inch. THEN for the next 5 weeks he was normal - beautiful, and the heads were alternating this green color from one head to another. Kinda looked like pulsing-one head would be green - ten 2 seconds later the other one was green.. Now - for the last 2 days he has been stuck out a lot (still retracts though) - and I am hoping you tell me this is normal - or that maybe he is getting ready to lose a head?
<Looks starved to me>
The only 2 possible problems i need to mention are a) Seahorses have moved in and like to wrap their tails around the feather dusters base, but it doesn't look like they are squeezing..
<Still likely bothering it excessively... I'd move it>
b) my water parameters are good -except for one thing the LFS told me i didn't need to worry about - the calcium is high, according to the testing kit - 600-700 ppm,
<Way too high>
could this affect the feather duster?
<Yes>
I have been mixing phytoplankton with brine shrimp and target feeding him, the coral, and the xenia..
Thank you for any info you can provide. and sorry for too many questions...
for now i am leaving a link to the website, if that's OK, and then going to put a link on the main page - under my "donate" section.. and HOPEFULLY - if i ever get done dumping $$ into the tank, i will be sending a donation myself!

Have a GREAT day!
