Help with kena trees

I split a white kena tree weeks ago and the trees seem to be slumped over and go from open to closed . the trees are in diferent areas of the tank and both mimic each other. The tank s other inhabitants are all doing great Zoos, Frogspawn, Mushrooms and Cabbage. I'll try to post pictures if needed . Thanks in advance​

 

mine does this. if its sliming then it might be growing. thats what mine does. mines gotten bigger though in the past few weeks since i got new lights, good luck!

 

Im not sure your supposed to split them. Most just cut off a branch or two to frag them. Splitting it might of damaged it. I'm no expert on this though.
