Leather coral, open or not?

[bob`_your_dog]

I bought this guy last week friday, so it's been over a week. It's been closed up all week and over the past two days he seems to be open a little. Will it open up completely like the other leathers or do just a few fealers come out.

Sorry, but does anyone know the scientific name for this dude aswell?

I hear its supposed to open within 3 days. I had one (got from live aquaria.com) and it never opened after 2 weeks. When I moved it, I noticed an ulgy hole in it. I got rid of it so fast incase if something unwanted was living in it.

it looks more like a devils finger/hand to me!. Some shops also call them cathedral corals
mine looks like this

They shrink up alot at night, mine shrinks to less than a 1/4 of its full size.
