Give it a week before making any serious conclusions. Besides being one of the easier to care for soft corals, Kenya trees (or so i have been told more than once) act as a great water quality gauge. they can take several days to acclimate and adjust, but once they are happy in your tank, they will tell you how the tank is doing. When lighting, temp, flow, nutrient export, salinity, and trace elements are where they should be, they'll perk up wave happily and can even grow like weeds. I had them in a 50g tank that was being a bit neglected. They seemed to shrivel in and never came out. Did some water changes, added some trace elements, etc and within a week they were all hanging out. If you see em start dropping branches, thats not a bad sign. Thats how they propogate. They'll drop branches and depending on flow, where ever the branches land, a new tree will grow. WHen mine got to 3" Tall and had a head the size of a baseball, they started dropping branches like they were being hit with a weed eater. Next thing i knew, i had 8 new trees in a couple weeks in different spots. Thats just the branches that landed somewhere that got enough light. Who knows how many went to dark places.
