New plants and new disease to identify

Well I finally got tired of plastic plants and put some live ones in. Two of
which
I wasn't able to identify with my (extremely) limited plant knowledge. I
figured for
$3 it wasn't a bad deal. Can anyone Identify them by the pics on my tank
page?

Also I had noticed for a few days that one of my guppies fins started to get
shorter.
A few days later I noticed a white 'line' around the edge of the tail fin.
At this point
I took her out and put her into a quarantine tank I have. The tank is at
80F with
about 1/2 the amount of salt suggested for a 10 gal tank. She is also
missing some
scales below the dorsal fin. I am not aware of any mechanical damage that
could
have happened. Anyone have any suggestions on this one? I didn't add the
new
plants until after the sick fish was taken out so they are not related.

Please take a look and let me know if you can identify anything in there
