It sounds like Hydrocotyle leucocephala, a very pretty plant, if pruned

I just give them a big mass in a plastic bag, and they either bunch them or
let them float.  On the other hand, I don't ask very much in return, only
an occasional magazine.

There is a large variety and a small variety of Java fern.  Perhaps you
have the small one.  I only get leaves about 1 to a little over 2 inches
long on them.  The large variety can make leaves around 8 inches long, and
often the leaves are three-pointed, with two smaller 'wings' below the main
tip.  Neither is a rosette plant.  Rather, they have stems with leaves that
come off every 2-5 millimeters for the small variety.

It may not be a trace element problem.  You might need more potassium.  I
always want to consider potassium whenever I hear about older leaves dying
back.  If the older leaves of the swords get tiny little holes that grow
until the veins are left but most of the rest of the tissue is gone, then
that sounds like potassium deficiency.
