Sand for substrate feeders
What's a good sand for substrate feeding fish like Geophagus, Thorichthys, Corydoras, Pangio, Botia, and similar species? I'm looking for a nice sand that's either black, brown, or white. The sand also has to be able to pass through the gills of fish like Geophagus and Thorichthys (i.e. spurt through the gills when they pick up mouthfuls of substrate to search for food in) easily. I'm currently stuck with whatever Lowe's and Petsmart have to offer...
