What is this coral

[russells55]

Hi all

I have had this frag for atleast 2 years but I though when I got it , it was like a green hair.

I have moved it around some tanks over this year

Maybe it’s not green?

More light , less light
What even is this coral?

Cheers

Looks like an unhappy toadstool. The polyps are trying to come out it seems.

Looks like a leather toadstool.

I think your right
It does match some Google pictures too

I guess maybe it is getting too much light. It’s at the top ish of my rock pile

They love light. Check your flow and params.
