I add the cuttlebone to harden the water. I do it for my guppies and Endler's livebearer's as well. I've never seen the shrimp actually ON the cuttlebone bit like they are eating it. I also read the suggestion for shrimp on Frank's yahoogroups list and since it's an easy thing to do, I tried it. It didn't hurt anything but I don't know if it's NECESSARY. I'm not a chemist type....I'm doing really good to halfway understand the nitrogenous waste cycle (wink). I also feed the shrimp Crab Cuisine at least once a week. I also stopped adding salt to the shrimp tank water and also stopped the Kent Marine Iodine...and boosted the tank population to 10+ shrimp and that's when they started breeding. Who knows which variable tipped the scale to the breeding side (shrug).
