I grow A. b. var. nana, A. b. var. barteri, A.b. var. 
angustifolia, A. b. var. caladiifolia, A. 'Coffeefolia, A. 
gracilis, A. afzelli and A. heterophylla (syn. A. congensis) 
permanently submerged in my tanks.  I have had all specimens 
except for A. gracilis for 5+ years.  Not only do they grow well, 
but all the A. barteri varieties bloom regularly, and the A. 
heterophylla has bloomed twice in that period.  The only one that 
I find "touchy" is the A. gracilis.

No, actually, most of the plants available in the trade _are_ 
varieties of A. barteri.  This is an _extremely_ variable plant, 
and all varieties do very well as aquarium plants.  It's sort of 
the C. wendtii of the Anubias world.

This is good advice for any plant with a rotting rhizome.  Cut 
back until you get to clean health tissue then replant.

I think you've answered your own question.

- Poor light
- No supplemental CO2
- No regular water changes
and probably
- nutrient poor (plain gravel) substrate

Except for A. gracilis, I have never had any problem moving 
Anubias.  They're pretty tough.  Yes, I do trim the roots when I 
move one.  It make it easier to plant again, and I believe it gets 
the plants to start developing new roots in its new home faster.

Yes, they will LOVE your plant >;-)
