We've got a FL Ricordea that has been in our tank for a little over a month. At first it was doing good, attached itself within a few hours and opened up and seemed to be growing. Over last two weeks though it seems to be shrinking in size and not really opening up. We've got 2 other mushrooms that are doing great as our the rest of our corals and creatures. The Ricordea is midway up under direct lighting and in an area of moderate flow. Is there a way to bring him back to life? Also how can you safely move them once they are attached if the position in the tank is the issue? Thanks in advance for any help.
