Cow vertebra in tank?
I have a decent-sized cow vertebra, about 4" long, which I was thinking would look cool in a tank. As I recall, it spent awhile in a field with other bones, then was boiled to clean it, then sat in a wheelbarrow for awhile before I bought it and soaked it in a bucket of water for two weeks. How can I make sure it doesn't have any chemical stuff on it? I think it would be a cool thing to have in my 65G...
