Thanks to everyone who mentored me through purchasing cuttlebone. I strongly suggest anyone with shrimp who does not have cuttlebone to go get some and put it in your filter. My cherry shrimp have gone from dull maroon to eye popping cherry and my yellow shrimp have gone from dirty blond to whizz bang fluorescent. All of this has happened in about a week. I am so grateful for this list. Cheers, Shango _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
