So Betty, once and for all. It isn't that the shrimp eat the Cuttlebone which helps the shell, it is that the water is harder and THAT helps the shell? -----Original Message----- From: gsas-member-bounces@thekrib.com [mailto:gsas-member-bounces@thekrib.com] On Behalf Of Betty Goetz Sent: Tuesday, October 09, 2007 6:47 AM To: Greater Seattle Aquarium Society member chat Subject: Re: [GSAS-Member] cuttlebone or not I use cuttlebone bits in my red cherry shrimp tanks. They breed (wink). Yes, raising hardness requires adding stuff to my water because it's very soft. If you don't add cuttlebone bits or crushed coral (I've done both), you add something else (shrug).
