Hello all, I have recently started a 10g aquarium I plan on getting multifasciatus or brevis. I got the normal variety of sand so added crushed coral in a bad behind my filter. I'm working on getting it to the correct parameters for now. How many shellies should I get and does should I display the rocks on the back. Thanks as I'm new to Tanganyikans! Oh I should add I'm working on finding escargot shells.
