What is this ??

[Martin H. Lawton]

I was feeding my tank tonight and when I looked at one of my pieces I see this strange thing growing in between my palythoa's do not mind the Aiptasia I am in the middle of removing it.
Sorry about the picture...

 

[Reefing Madness]

Bad shot, to hard to identify

Looks like a Hydroid to me. Exact species I've no idea sorry.

 

[Martin H. Lawton]

Sorry for the late responce here is a closer picture... it looks like to be a part of the colony ...the skin looks to attached with the other polyps

here is a better picture ... I hope ..

Could it be a polyp that didn't forum right?... I don't think so because it doesn't have the same colors as the other polyps.

 

[Martin H. Lawton]

Forgot to add its the same size of the other polyps.

I have several like this too, open only at night. Looks like some filter feeders.

 

[DanConnor]

Are the tentacles branched? If so it might be a small filter feeding cucumber.

 

[Martin H. Lawton]

sorry again for the late response but no... and it doesn't move it just retracts when the lights turn on...

 

[Brian Kim]

Do you have something like this on your glass by any chance?

 

[Martin H. Lawton]

It's not on the glass it's on the rock with the polyps. It is the same size of the other polyps it just looks different it doesn't move it just retracts.

Here are some pictures I found to be similar to the one on your picture. Hope this helps
it will be in the following order: Aiptasia anemone, Majano Anemone and Pseudocorynactis. All of them are know to be a plague and will sting your corals btw.

 

[Martin H. Lawton]

Looking at other pictures it looks to be some type of majano... but I'm only 75% sure.. either way it's got to go ... whats confusing me is the fact it's seems to be connected with the foot or body of the host coral .. it's like it's one with it..

I got some new live rock a few weeks ago and notice this growing. It looked like tubeworms when closed but now it seems like it could be aiptasia?

[Sabellafella]

1st picture theres an aptasia what you have circle are pseudocorynactis

 

[AllSignsPointToFish]

Does anyone have any more information on the majano zapper laser? I've been looking for some sort of specifications (i.e., wattage, wavelength, etc.), but information seems kinda sketchy.

I've noticed I have a few aiptasia or majano anemones growing on my live rock, so I'd like to try out the laser zapper before they get out of control :)
