Is this rizome rot?

What is causing these holes and loss of roots?is it water quality or too much light or too much flow or rizome rot?

Could it be the start of rizome rot and if so should I trim it or leave it?

Everything looks very good to my eye. I've kept and propagated Anubias and Bolbitis for 25 years, and have never seen rizome rot. I don't see it there - the plants look great.

It looks like biofilm and should not be a problem.

You can blow it off with a turkey baster, to be able to see if it is indeed "attacking" the plant.

But I wouldn't think so.
