Help ID Leather

Got this from a friend that was breaking his tank down. I think its a green nepthea, but want confirmation as I'm not all that familiar with leathers. Thanks

Probably green sinularia, but could be nepthea. Supposedly you need to look at the skeleton under microscope to be sure.

+1 Sinularia,

Pretty common round here.

I am just wondering....I have green nepthea (well what I bought as green nepthea from someone I trust). It looks identical. Mine is a small frag but I mean....how can anyone say one way or another if it is indeed true it has to be looked at under a microscope?

Really just curious. I trust my store (Your Reef) who is now breaking into selling online. I have been with them for years though and watched and waited for him to frag his nepthea for a year before I got it. How can one really be sure or even have people try to guess if it needs a microscope?

Here is mine, mother colony looked like the OP's. It is just a picture but I mean, I think it looked the same. Is there really no other way to tell? It is hard to tell if the colors are the same. This is with flash. This frag is the brightest thing in the tank and only 1.5 inches. Is it even worth asking for conformation if a microscope is needed? Is one brighter green? Do the polyps look the same? Are there any other possible differences just to shed light? Thank you for any thoughts, really just curious. It is my favorite coral, even as small as it is.

Sorry for putting it in the wrong forum, didn't even notice the sub forum for coral ID. Thanks for the help.

I have Green Nepthea and Green Sinularia. The Nepthea is one great big stalk/tree, doesn't spread across multiple rocks like the sinularia. The Nepthea is also very slow growing in comparison.
