Help with Hitchhiker ID  12/30/08
Hi, thank you for your time and help.
<Hello Andrew, Minh at your service.>
I brought home a Bubble Coral about two weeks ago which is doing extremely well. Several days ago I noticed two little unknown hitchhikers of sorts, growing on both sides of the lower part of the Bubble Coral. I have attached two pictures that show both the top and side's of these little things, it looks to me like maybe some type of anemone.. It has sort of a light green base and disc with light brown tentacles, it looks as though it might have a mouth or something circular in the center and is about a 1/4in long, if it is an anemone should I remove it?
<Based on the photos and your description of the animal in question, they appear to be Anemonia majano. Many consider this species along with Aiptasia sp. to be pest anemones. You can arm yourself with more information and ultimately decide the best course of action by reviewing this link: http://www.wetwebmedia.com/anemoniafaqs.htm.>
I searched around on the site and some things looked similar but I just couldn't seem to convince myself, I apologize for another routine question.
<No worries at all, nothing is routine in this hobby.>
Thank you, I appreciate any help you can give me.
<You're welcome. Cheers, Minh Huynh>

Anemone ID, Friend Or Foe 12/18/08
Hello Crew,
<Hi Sandra.>
Thanks for taking the time to give your input.
<You're welcome.>
Can you please tell me if the attached picture is a Majano or a Tulip Anemone? I have no real knowledge of anemones and need to know if this hitchhiker
should stay or go. If it is neither, a heads up as to what it is would be appreciated.
<Sure looks like a Tulip Anemone to me, nice looking also.>
Thanks again,
<You're welcome. James (Salty Dog)>

Hitch Hiking Disc ID 12/14/08
Hello WWM Crew,
I have about 10 of these discs on my live rock.. all appear to be thriving.
They move around until they find a spot they like. If you touch them they pull right into a hole/ base and shrivel up. They have a base like a mushroom/ anemone. I believe it may be a variety of Epicystis sp. from other posts on your site. Here are some pics..
<Hmm, could be Epicystis sp. (a little bleached)...>

<It's hard to tell from the photos, but they might also be some type of Corallimorph (i.e. mushrooms, etc.).>
Thanks for all your help,
Nick

Can you help me id this?  Thalassianthus   12/16/08
Thanks for such an informative site. Many of us really trust you experience.
<Thank you for your kind words.>
Attached are two pictures I took of something growing in my reef tank � I was hoping you might tell me what it is - and what I should do � if anything. They are beginning to populate and are very difficult (impossible) to remove from the rock. Is it some form of anemone?
<Yes. I am sure this is a Thalassianthus species or at least closely related. Do a WWM search for this genus to find further posts. The picture nicely shows small grape-like balls, these are nematospheres, quite typical for this genus and only found in one anemone family. Can become a pest. I have them in a fish/soft coral tank without any problems and think they are beautiful. But in SPS tanks or tanks with sensitive animals like clams they may be problematic, especially when propagating like crazy.>
If so, if I try to remove them and do a partial job - will I create a pollution problem?
<As I wrote to another poster, I'd try: Careful (!) injection of boiling water, muriatic acid or sodium hydroxide solution as described at http://www.wetwebmedia.com/ca/cav1i3/aiptasia_impressions/aiptaisia_impressions.htm under �other chemicals�. Don't kill too many at the same time and always filter with carbon and also watch the pH when using pH changing substances. You can also try to remove them with an old, but clean tooth brush, just brush the foot for a few minutes and the animal may eventually decide to loosen its grip. Then, they can be removed with fingernails or an old knife or piece of plastic. This method needs some practice, be aware that they are able to burn at least the underside of your arms, possibly even your fingers. Carbon should also be applied when going this route. Removing them in one piece is more difficult, but might be worth it (you'll avoid most of the pollution) and some fellow hobbyists with less sensitive animals or fish tanks might actually be happy about them.>
One is actually growing on the shell of my clam!!
<Needs to go.>
My tank: 125 gallons with about 130 pounds of life rock taken directly from a friend's 400g tank. 30 gallon sump/refugium Skimmer. Change water every other week (15g). 3 x 150 MH lights. 4 x 96 actinic lights. 8 moon lights.
Thank you for any help you can provide.

Anemone ID 12/2/08
Hi.
<Hi Jessy here>
I have been pointed to this site for identification of a hitchhiker on some new living rock.
Need to know what it is as maybe its a baddy. But if not I need to know how to care for it.
Thanks in advance.
<Yep you've got yourself a majano anemone. They will rapidly reproduce and therein lies the "pest" problem. They are one of the prettier pests in my opinion, but you'll want to remove it nonetheless. Read more FAQ's here
http://www.wetwebmedia.com/anemoniafaqs.htm for removal ideas.>
