Hello Friends, I have come across the suggestion that putting a piece of Cuttlebone in my shrimp tank may be a good thing for the calcium for their shells. I have done a bit of research and found that many folks deem it unnecessary unless I am breeding snail. Shrimp somehow don't need it..or do they. I am not very confident in the sources I have come across. Do any of you have good experience with this debate that you could share? And also, what is Cuttlebone? No one explains what exactly this mysterious stuff is. Thanks Shango ________________________________________________________ Shango Los Phone: 206-595-9006 Fax: 206-729-5271 www.ShangoLos.com www.SunbreakShines.com _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
