I do have some anubias which I heard they did not like so much,
Yes I have a Frontosa and a Livingstoni which upto now have not done any digging. My convicts dig like crazy but then they are like rabbits and constantly breeding!
My Firemouths have dug once or twice but also only for breeding purposes. Some of the cichlids I have do like some sort of plant cover.
I will certainly keep you guys posted as this tank unfolds.
