I have recently upped the current in my tank with a powerhead. All the
other plants seem to like it but the Star Grass leaf ends are now going
black. Don't think it likes being tossed in the current. I will move it
back, behind the power head and see what happens.

and Hey! Why should Paul K. in Mississippi know about X-files? It's filmed
here in spooky Vancouver, you know. :) Anyone want David or Jillian's
autograph?? They are filming here at UBC all the time.
