I bought a finger leather app. 2 weeks or so ago and when I first put it in the tank it was mad from moving of course then it opened up and looked pretty but the stalk started wilting and getting soft.I thought maybe it didn't like it where it was so I moved it and after a day or so it would open but the stalk kept getting limper.Once it lays down the stalk gets hard again..I moved it yesterday to an area that had some rock to support it better but it is like the stalk became butter and just wilted among the rock.Stalk is hard now but it looks bad.The other coral I bought is doing great.I only bought 1 piece of the finger leather..The three pieces of colt coral,,the mushrooms,feather duster and cabbage coral are fine.Any ideas why he is sooo unhappy and is he dieing?What should I do?
