Sevs will leave anubias and java fern alone. I also find no cichlids like hornwort. I have a bunch in my 120 with Altifrons, Red heads and some other cichlids and rainbows.
In my LFS they have some Mbuna with hornwort and they won't eat it.
Amazon swords seem to be ignored by my geos but I'm not sure about severums, the Rotkeil I used to have completely ignored plants
