Got any ID for this thing I found.....

[Aliie]

I'm trying to determine if it is fish safe.

Bottom left hand corner on the tank.

I have had one a long time ago with fish: no problem that I recall, but wait for an id and life requirements. it may be too fragile to keep: I can say it was, back 20 years ago.

 

[Aliie]

It's been hiding in my 12 gal nano and went from 1 to 5 in just a year. Not thinking it's hard to keep. It never ate a fish but I only had a goby in there.

I put it in the new tank and was thinking about putting a small clown in there and don't want it to be lunch for the thing. I'll wait for sure on an id Sk8r.

Is that not a tube anemone

 

[Reefing102]

i believe it is a tube anemone

 

[Aliie]

Tube anemone was a thought of some others but it doesn't look loke the few tubes I've seen. It looks like it's actually growing out of the rock. It totally withdraws when I reach into the tank. But as long as it's fish safe I guess it doesn't matter.

You wouldn't go from 1 to 5 tube anemones.

I looks like a really big aptasia to me. I might also be a curlycue anemone (Bartholomea annulata), but I can't see the tentacles well enough to know.

Where did that piece of rock come from. Pacific, Atlantic, Caribbean?

Its not a tube anemone. There is one big anemone and 4 little ones attached to a rock. There is no tube.

Tube anemones don't reproduce like that and unless I'm mistaken, there actually needs to be a tube for it to be a tube anemone.

I think it is just a really big aptasia and its babies.

Ya know... I have something that looks a lot like that. I sure would like to know myself. mine has been in the tank since i started it so about six to seven months and haven't seen any reproductions of it yet. When I saw it I moved the rock work around and put another rock on top of it that made like a small cave. It hasn't moved or gotten any smaller. And it gets no light at all. I have to use a flashlight to see it. I will be watching this thread.

 

[Aliie]

I still haven't been able to find a pic of this kind of aptasia. i searched thru a few hundred and not found any that are clear/white. These have no tube like parts at all. Let me see if I can get a better pic of them.

I stink at pics. This is what it looks loke when it retracts it's tentecals.

 

[phender]

It is not unusual for aptasia to be clear white. Especially if the tank is not well lit or the rock has been in the shade.

Not to mention Aiptasia is a genus containing multiple species. Some are quite a bit larger then the common invaders to our coral gardens.

fwiw: If I remember correctly, one of the traits of the genus is a retracting column, like your latest picture appears to show.

I have brown and white ones in my 10g that I just let them grow. That looks like aiptasia to me, you don't have to get rid of them. People just do because they can sting your corals and they spread fast. Plus they take the neutrients in your water that you want your corals to get.

I do however get rid of them in my main tank.
