Please help, what is this?

[Finding_Nemo]

Hi i bought it today. I first thought it is dying. Was about the size of a dollar coin but now I can see has expanded 3 times.
It's around flat like a disc and it has something like a mouth in the center. Has also an attaching soft base. When removed from water it produces a strong sulfuric smell.

I placed it on a rock with less flow, but i don't know if this is its place.
Can you please identify so I can read about carrying this stuff?
Thanks

Almost looks like some sort of mushroom to me. They are generally hardy and can come along as hitchhikers in new live rock.

[reefboy1994]

looks like a mushroom to me. maybe rhodactus or discomussa (sp.?)

[cmacld]

looks like a hairy mushroom or possibly a yuma ric of some sort

[iamwrasseman]

ita a mushroom 99% the other 1% is possiably a flower anonome

[Finding_Nemo]

yes i Google the names provided here and saw like 80% similarities between mushrooms and my thing.
Not sure about the attaching leg but mine has a suction circle, same as a sea anemone i have. It attached very fast on the rock, almost instantly and i could see it moving. Also from the central mouth?? there are some white curly expandable tentacles. The extensions/other small tentacles are in a shape of a cross (not straight as the mushrooms I've seen). and there are reddish greenish color and white.

I got better photos than before.

if it attached quickly then its an anemone, mushrooms are very slow to grip or form on rockwork and they dont move like an anemone either.

interesting one here, i thought maybe rhodactus or discomussa (sp.?) too but taging along

[SNAKEMANVET]

It's defiantly a mushroom of some sorts,I have one that is very similar.

[iamwrasseman]

did you see it has a suction cup like an anomone ? thats whats throwing me a curveball .whats with it attaching quickly with the cup ? mushrooms dont do that ,they are slow attachers .

Hi, it's a mushroom 100% , but it looks like a hairy marble!!

[theisdept]

I would also say a mushroom- maybe similar to the watermelon variety.

Mushroom, and quite beautiful I might add!

[Finding_Nemo]

ok i am not sure if this helps but i just have placed a piece of shrimp on top of it and it had closed over it. Here's a pic; could still be a mushroom?

[iamwrasseman]

Anenome if hes eating like that .you said he had a suction cup type base also right ? i have both and my mushrooms never ate like that but my anonome,s do for sure .has it moved at all from its original perch ?

No it's in the same place. Attached by a rock. Only when some creature comes around it shrinks. When i put food it raises the base in real time and it becomes like in the picture.
I need to know about it more. I don't know if it likes bottom sand or attached by the rock. I was using it under a strong flow and didn't like it and removed itself. Now this place looks ok to her.
I only have 4 T8 x 48 mm and a T5 36mm making in total about 180 watt light. My tank is 90 gallons. Everything else does Ok under this light. I hope this one will do as well.

Thats a fancy looking mushroom you got there they like low flow low light let it attach to a rock

[RGC]

mushroom. My hairy mushrooms eat just like that. low flow , low light

[SNAKEMANVET]

I got a pic of my mushroom,looks like yours except differant color.

[Finding_Nemo]

hey Snakemanvet thanks so much, so it's a shroom!
How often should feed her?
Low light and less water movement right?

[SNAKEMANVET]

I give it a squirt of mysis with the turkey baster about once a month.

[SNAKEMANVET]

Mine is under low light,and low flow.
