Roy, I may have torn some roots, but I didn't purposely clip any. Didn't know to! So far so good with it in the 55g. 10g still looks a bit ugly. Like I say, the sword's roots took over the entire bottom of the 10g. The whole substrate moved in the 'freeing' process. LOL. I did an extra 80% WC in the 10g just for good measure.
