We saw some cool flavored cuttlebones in the bird section and gave them a try last night – the turts seemed to love vanilla, and grape, and orange cuttlebone – all were a big hit, but it kind of seemed to stain the water a little - especially the orange and grape. I'm not sure how much, or if it was just my imagination. We’re hoping it’s not harmful – we’ll probably feed it again, but only as a treat and no more than they’ll eat right away (ideally, the day before a water change). BUT, boy oh boy does our big turtle love some grape cuttlebone.
Anybody else feed this stuff?
