Planted Tank Guru
my java fern is ill and nobody seems to know what it is. i believe it may be a disease, though i have never heard of it in an aquatic plant. none of my other plants are affected, but ferns in multiple tanks all got it. the ferns developed brown splotches on the leaves, the splotches spread, eventually the leaves rotted away. the rotting splotches have a crips outline, they dont really fade into the healthy tissue; there is a clear division.
