I think that is the case with certain cichlids, some will dig up and some will eat your plants but that isnt the case with all. You can get plant safe species.All looking really good.
I was interested to see how your cichlids got on with your plants, because apparently the popular notion is that you can't have plants in a tank with cichlids, especially the larger ones.
Ive found mine to be perfectly fine with most plants that ive added to the tank. Only problem ive had is my big Bocourti took exception to some vallisneria and a certain type of sword i put in but other than that ive been lucky so far.
