java fern turning black?

[RoxyDog]

my nice big java fern is turning black and getting holes.  it's only been in my tank about a week, and the other javas are fine.  the lighting is low, 1.3 wpg, any thoughts?  should I trim the black parts off?

Likely transplant shock.

A few things though....

Make sure the rhizome isn't buried.  Additionally, make sure there is good water movement along the rhizome.

Don't trim off any leaves unless they really start falling apart.

I hope it is just shock from coming to it's new home.
don't know if it's gettng good water movement, it's a big plant, very low and dense.
I have half of my javas planted and half not, there appears to be no difference between planting them or not, for me anyway.  this one is not planted though...

My ferns do the same when I dose less iron ferts, or when the I raise the temperature.  So maybe that's was is different between its previous and new conditions?

it came fom Nelson's discus tank, now in my goldfish tank, so there is defintely a temp difference.

I'm no plant expert, but I suspect it wouldn't be so much of a temp difference as concentrations of minerals, nutrients, etc. The plant has probably adjusted to a certain exchange level, and with different concentrations in the new tank, has to adapt.
