I'm feeding my mbuna Northfin Veggie pellets as their daily staple. When I drop the pellets in, it's a fish-nado feeding frenzy. Very few pellets reach the bottom, and those that do are quickly picked up. So far, so good, right? But I keep coming back to the idea that mbuna are grazers in their natural habitat. Gobbling food near the surface is not their natural way of eating. Wouldn't it be better to place the pellets on the rocks somehow, and let the fish "graze" the food off the rocks? Has anyone tried this? How can it be done?
