I couldn't tell from the FTS - but you know that Anubias has to be tied to something - that you don't want to have the rhizome in the substrate, right (roots coming out of the rhizome-OK, but the rhizome itself has to be in water, not substrate)?
I didnt tie the anubias to anything, but I did make sure to pull the plant up a bit after planting to totally expose the rhisome. I just checked it again and think it will be okay. Does it HAVE to be tied to something? Maybe I should tie it to the driftwood, but that may look awkward.
