Hey Matt can you get a pic of them closed up?
The reason I said conclusively they are Nukes is it looks like they have sediment in their tissue. You can see it in the last pic of them closed up, which I don't think the anemones have a speckled tissue......See if you can get a pic of them closed up.......
Those are sweet anemones, I had a couple but have lost their location in the tank.....Could be dead to I suppose.
