| Tofu good for shiro?? Hi guys, I'm wondering if anybody else gives tofu to their koi beside the regular food. I give tofu to my koi because it have very high calcium content. Up to 89% per 100mg. I also notice that the shiro on my koi improve when I feed them tofu. It could be just my imagination so I would like to find out from fellow hobbyists who also give tofu to their koi. Notice anything? SF |
