LF Xenia eating Nudibranch (Or what have you)

[Lampshade]

I never knew that xenia is a weed. I almost bought some for my 120 gal...

Depends on the tank. Xenia in my tank just won't grow. I have other sofites that grow like weeds, and SPS/LPS that grow as well. Xenia just dies....

[Blue Ram]

I also have to do a bunch of pruning. Is it safe to do inside the tank? I have a large piece of rock that my clam is attached to that is overrun with zenia and would prefer not to remove the rock/clam from the tank.
