With a rapid onset "something eating them" seems like the only thing
likely.  I was talking to the plant person at my favorite LFS (yes, they
actually have a specialist, and she has experience) about some
ugly-looking echinodorus in some of their tanks.  They had a problem with
sword plants where the entire central part of the leaves would get paper
thin and turn brown and lacy literally overnight.  She was positive that
it was caused by plecos rasping the leaves.  The shop sells a lot of
odd-ball plecos, and they seem to be in most every tank.

Could that be the problem with the giant hygro?
