I went to Pet Supplies Plus today and picked up a potted Kleiner bar sword and a pot of Marsilea Quadrifolia. (They gave a pot of weak looking HM for free also) I know you can trim the emmersed growth, but does trimming off the Emmersed growth send them into shock and thus a greater chance of completely losing them? Or, should I leave the Emmersed growth if there is a greater survival rate?
