Anubia barteri disintegrated

My anubia barteri roots turned brown and leaves started falling. Did they rot? Or is it anubias disease? The rhizomes were not buried so I don't know what was my mistake.


Many leaves turned like the left one and disattached. One seems healthy. I bought one and cut the rhizomes into many.


Ew!

 

How long ago did you buy them? Sometimes plants that are grown out of water melt when put in water. Then they come back.

 

About two months ago. Though my sense of time is not at its best.
I heard about that but then the roots are supposed to remain healthy, right?

 

Okay now my bigger anubia started developing the same symptom. This is its newest leaf!

Aren't they supposed to be the easiest plant?? It must be the disease but still sucks because I can't get any tratment (assuming there is one) before quarantine ends.

 

Is the rhyzome super glued or wrapped around (using fishing line etc.) something? I never had any luck super gluing anubias-- they would rot and disintegrate. I bought new anubias nanas and I tied them onto rock and driftwood and they are producing new leaves now.

 

They were stuck in this decoration holes with no glue.

The tip of the remaining nana roots in turning brown and the hole in the Big anubia getting bigger. I did some research on lack of nutrients, co2 and water flow but found nothing.
I increased the light and pointed the filter in that direction.
