Coral Polyp Extrusion site

[davejnz]

Eric,I forgot to mention,both corals were undergoing the extrusions at the same time.With the Caulastrea,the colony actually had multiple extrusions.These occured shortly after a period of rapid growth where the polyps split,some split into 3 and the colony became very crowded.The extrusions took place on these areas where the corallum didn't grow fast enough to support the extra polyps.
BTW,i found one of the extrusions alive and growing under the colony between some LR.The Euphyllia extrusion got lost in the aquascape.

Is that what this Ric is doing, or is something else entirely going on?

 

[EricHugo]

Yes, I was going to comment on that in the other thread. I'm not sure. The smaller vesicles developing on the other tentacles are common on coralimorphs. and the larger ones seem like extreme examples, and I am not sure if this is a related behavior or not but it certainly bears a similar appearance. I have never seen or heard of corallimorphs losing these vesicles or forming daughter colonies, though. Maybe its a relic behavior from long ago when they used to have skeletons?

Now that would be fascinating!Interesting thought.

My pocillopora is doing a very similar thing to that ricordia picture.Is this more than likely what is referred to as "polyp bailout"?Noticed it start to happen as it "colored up" from being brown when I got it.

Eric,

I just acquired the Ricordea last week. I acclimated it to my tank, and everything looked normal. Then a couple of days ago it looked like this. All of my tank parameters are w/in normal limits.

hi eric everyone else has lps they are showing pictures of is that all you want or would soft corals be of intrest? i have a sarcopyton that is dripping like a melting candle. it is collecting on a rock beneath it and looks as if it may form a new coral. wife has the camera right now but i can get you a pic later if you like.

 

[EricHugo]

absolutely...bring it on. I have a couple of gorgonians doing what appears to be a similar behavior. Would love a soft coral confirmation

 

[jakano]

hi eric here is the leather coral i was talking about. as you can see it is oozing down onto the rock below. you can also see part of my pagoda coral that has some dead spots. i went away on vacation and the girl watching my tank didnt know sand should not have been blown onto it and allowed to stay there.so parts died. anyway i hope this is what you are looking for.

 

[EricHugo]

can you get a closer shot of that area and send it to me by email to eborneman@uh.edu? Thanks!

Posted a concern about what was happening to my favia in another thread, Eric chimmed in and said it was "multiple coral polyp extrusions" and directed me to this pinned thread.

Thanks Eric (ah a personel message from the great Mr. Hugo )

Anyway, Eric what can I expect to happen to the brain, time frame, should I do anything, etc.

Here are the pics.

If you would be so kind as to keep track of the extrusions and make notes if any form daugher colonies I would be much obliged!

Thanks

E

 

[rioreef]

Will do.

Goniopora stokesii

Goniopora stokesii

Eric,
2 days ago my G. stokesii, which I have had since last January produced about 50 "stalkless poyps". Many were lost in the rockwork but I managed to catch 20 or so which I have placed in a perforated container.
They have not shown much change since, only a couple have expanded. Iam putting DT's oyster eggs & cyclopeeze in.
The parent colony, which had produced 3 satellite colonies, does not look any different since.
Lighting is 10000K MH + actinic 03. Substrate is soft, fine sand. Other parameters are as normally kept in reef tanks.

I have a friend who has a Caulastrea with a very severe case of this condition. Last time I seen this colony it was one big cluster, I could not understand why there were no 'heads' I will go visit him tomorrow and get some pictures.
I also have a hammer and a frogspawn (Euphyllias?) that have both done this and I have seen the daughters form once the 'bubble' retracts or deflates.
All 3 of these corals are under PC lighting in systems running less than a year.
Ill get some pictures to you.

 

[EricHugo]

Thnaks, Glove.

Chris - thanks, also, for the email and photos...very interesting, even if not an extrusion - have never heard of or seen this before.

 

[rockdr]

I have been wondering if this is what my brain has been doing as well.

 

[EricHugo]

yup - that's it! Can you please repost if you get a duaghter colony, separation with no daughter colony, or resorption? Thanks!!

 

[rockdr]

no prob! It has been really small for months and I wasnt sure what was happening but in the last few weeks it has really taken off. will keep you posted
thanks
Kelsey
PS. From what I heard, you made quite an impression on the guys from LARC at your talk in Mandeville, I was a member there and now am in MARSH after our move.

 

[cmhollis]

Eric,

You remember the Ricordea I posted earlier?

Before:

After:

I think it is clear that the thing has experienced explosive growth since my earlier photo. The first photo was taken on 10/25, the 2nd photo was today, about 7 weeks later.

 

[poopsko24]

mabey this is the place for these.....

I also have an elegance and a hammer doing the same thing....I'll get better pics of those and post.
