1ft for a Frontosa, even juvies, is kinda small & will stunt the growth of your Frontosa. At least a 2ft tank for juvenile Frontosa, preferably 3ft. Apparently Fronts get spooked pretty easily so less rocks may be the way to go.

As for Malawi Mbuna cichlids - more & more rocks. Sand is preferred, but they do fine with small-sized gravel as well.

Happy Fishkeeping!
