new critter...no pic

[Haloway]

Hey everyone!

I just discovered new life in my aquarium when shining my flashlight into the tank tonight. But, I'm not sure if its good life or bad life. The subjects in question has an anenome type structure. The tentacles and body are transparent, and the tips of the tentacles are white.

Something else that interested me...when the light from the flashlight was put on the new critter it retracted its tentacles and closed up. That might be why i can't see them during they day.

They seem to be showing up in areas of little current.

Can anyone tell me what these things are? Hopefully they aren't a species like aptasia :?

Thanks for the help,

Kevin

Without pix you will not get a positive ID..and honestly even an educated guess given just from your description will probably be inaccurate as well...

Here is my guess though..one of two
1) your fear aiptasia (pest)
2) hydroids (tolerable)

Haloway,

Let me ditto LordNikon:

Alright...i found a picture. This pic is a little deceiving b/c the body and tentacles are clear, but for some reason this one showed up better than the other pics i took of them.

Thanks for the help,

heres another picture of them...harder to see, but it's almost impossible to get a picture of them b/c they are so transparent.

Thanks for the help,

aptasia or majano. Not sure which. Either is bad....

I don't think it is a majano anemone, I unfortunatly have experience with vast numbers of them in various environments, and it doesn't look like any I have seen.

From your descriptions it sounds like it may be an aptaisia.

I'm going to disagree with both of the above guesses, as the picture is pretty fuzzy, and it's hard to tell.

The "transparent" tentacles are very reminescent of the hidden cup coral "Phyllangia", but the photophobic behavior is not.

Where is your LR from?

I'm going to disagree with both of the above guesses

I see your bet and I raise you..... :wink:

I bet its aptasia. Either way though we would definately a better picture if possible......

sorry about the picture quality...its hard getting close enough for the lense to focus.

its Figi live rock

Another question...I'm kinda glad that I got him out and about. About 2/3 of the way down the picture on the right side there is a black tubeworm type thing that comes out every so often. It is able to extend and retract the tube, and on the end there is white "feathers" like in a feather duster. I'm wondering if that is precicely what it is, a feather duster?

Thanks,

Kevin

I decided to try a new way of getting a close up of the thing. I used a magnifying glass in front of the lense.

Hopefully these will be of better help.

Thanks for your help,

Its a tough call for an ID..photophobic behavior. It could be a small tube worm aka feather duster...small tube worms sometimes with their "feathers" can look like transparent tentacles...

I've actually seen these guys here and there in our lab. Definitely an anemone. The last and second-last photos are actually fairly good representations.

They don't appear to be any of the "pest" species ofAiptasia. They reproduce in the tank, but not rapidly, and they have a DEFINITE preference for dark places. They are clear, and the tentacle tips are are expanded and white. They tend not to extend much, either, preferring to keep a mostly flat profile.

Not Aiptasia. They are big and open in the light. You can relax .

Those are Pseudocorynactis(or Corynactis). They are from the Corallimorphidae Family. They retract during the day and expand at night. They pose no threat to you aquarium inhabitants.

Woot Woot. Glad to hear they aren't aiptasia.

Thanks for the help everyone.
