|  Goby/Pistol Shrimp help ... Hi everyone, What type of substrate would you recommend for a pistol shrimp/goby pair? I'm currently using CaribSea's aragonite which I think might be a little too fine for the pistol shrimp? Also, have any of you had experiences w/ your rockwork toppling over from the pistol shrimp's constant digging of burrows? My rockwork has no PVC supports and basically just rests on top of the substrate. Thanks! |
