Substrate is an important part of your aquarium setup because a lot of animals dig in the ground to search for food. Also any live plants present need a safe hold and have to absorb the food in the ground through their roots. Digging fish always prefer rounded smooth substrate so as not to damage their bodies. Undergravel heating can only be recommended for medium-fine to coarse substrates because water circulation cannot really build up in very fine substrates; therefore most sands are unsuitable.
