Bad or good???

So, I have had my SW for about 2 weeks. I am cycling with a clown fish, and this thing has started growing by the base rock that I have in the tank... if you can see it, please help me ID it.

 

maybe aipstasia? can u get a clsoe up pic?

 

Unfortunately, that is as close to it as I can get... the more I zoom in the more distorted it gets...
If you double click the picture, it does get bigger

 

tentacles look too chubby for aiptasia to me..a closer pic would definitely help

 

I don't think it's aiptasia - like said above, the tentacles looks too big and chubby. But it's hard for me to tell from the picture. I have bad eyes!

 

haha yeah that would be my best guess

 

whoa, I'm so smart!! Thanks Sarah! And I can see - ahhh I feel so wonderful!

 

how about a feather duster? is it always visible? try to touch it and see if it retracts.

 

Well, it is always visible. It seems to be coming from the sand and not from the rock. When I turned on the moonlights tonight it seemed to close up...

Is Majano good or bad?

 

thank you!! I am quite amazing if I do say so myself.
