I keep a 125 with Africans. It can get dicey with some plants and some fish. Anubia seem to do okay with some trial and error. They don't eat them but there are reall diggers in some Rift fish and when they dig, they don't necessarily watch out for your plants. I find my diggers often like to dig under the edges of rocks so if I keep the plants back away from the edges, it helps the odds. One can also put the plants in pots and cover the top of the potted area with small rounded rocks that tend to slide when they dig under. They soon go somewhere else and leave that area alone. Lots of tricks can be used to ward off their normal behavior but the best is working with some of the open water fish that neither dig nor eat plants. Protomelas are good if you like the big guys. Copodichromis are another that give me little trouble.
