Id on possible mushroom?

[BL1]

I've had little success getting this coral ID'd, I'm hoping you guys can help.
It looks like a frilly mushroom but, it seems to have several mouths instead of one central mouth.

I agree it looks like a frilly mushroom. What color is it hard to tell in the lighting?

 

[BL1]

I tried to fix the white balance, it's mostly tan with a slight green tint to it.

 

[Luhring]

I do see what you are talking about multiple mouths but that may just very well be more tentacles growing out. Can you see one right in the center? I really think it is just a frilly mushroom.

 

[BL1]

I don't think there was one right in the center but, I have counted over 7 mouths on it. It's been that way since I bought it and it hasn't grow/split at all in 5 months.

 

[Luhring]

What did they say it was when you bought it? Did you buy it from your LFS?

 

[BL1]

I bought it from an online vendor that only listed it with a stock number, I thought it was a hairy mushroom from their picture.

This may be a hydnopora.

 

[Luhring]

Possible but I don't think so. They have more of a skeleton and this looks like a softie.

 

[Whisperer]

I wonder what made you say that. Have you seen it retracted?

 

[Sebastian J.]

If it really is a hairy mushroom, it will curl up into itself when fed. So I'd try target feeding it a tiny morsel and see what it does.

 

[Whisperer]

This is not a mushroom.

This is not a mushroom.

+1. Hydnophora is a good guess. The tissue margin looks very "stony coral" to me. If you can disturb it so the tentacles retract and take a photo it will probably be much easier to see the polyp and skeleton structure.

 

[Luhring]

I was just judging from the pic. I agree though try to make it retract and snap a pic.

I'm thinking hydno as well... looks like a nice frag, as hydnos go... Just watch the sweeper tentacles at night!
