any warning signs before your anubias died off??
The rhizome went from dark green, to light green, then started turning yellow~ish. The rhizome was nice, fat and firm, when it was dark green. As the color got lighter, it started turning mushy. When I took it out of the tank, it had a crunchy exterior and then the inside felt like mashed potato soaked in gravy. Squeezed it between my fingers, it felt like smashing a mealworm or the abdomen of an insect. Sorry, got a bit graphic there.
But don't worry, I yours is not gonna suffer the same fate as mine. I did some stupid things on my part. I used a regular box cutter (stupid me, it was lubricated with oil) to propagate the rhizomes. I cut all the roots and leaves off (with the same box cutter). I received it in the mail, the leaves was dying and the roots were old but healthy. Old roots = doesn't adhere to DW. So I cut them off so the new roots will attach nicely to my DW. I've read online that for java ferns, crypts, swords, and anubias, you have to remove the whole leaf/stalk if the leaf is dying, you can't just trim it like stem plants.
After a few weeks, new leaves and new roots sprouted on all the bare rhizomes. I even managed to grow 8 new leaves from a 1inch rhizome. Then few months later, that's when they suddenly started dying. I assume the stupid things I did on my part was the reason.
