I am going to dirt my tank soon and I need to know what red clay works. There is no Mexican Pottery Clay around my area but I found "Fimo Classic Clay" and "Sculpey Colored Polymer Clay".
Are polymer clays good and what are the general guidelines for safe clay to put in your tank? (i know it has to be red)
