There is also "turtle bone" sold by Zoo-Med
its identical to cuttle bone but usually a dollar more..lol just helps support a Herp supplier at the same time i guess if you pick this one...
Same thing goes for breaking it apart...
I'm Not sure why someone hasnt just thrown the crumbs for bird cuttle bone into a box for turtles and other Herps that use it...
that would be perfect.. cheeper and eaiser.. i use to toss a full cuttle bone in for the 2 adults but they never ate enough of it and it just messed up the tank you would never need a full cuttle bone in the tank unless you have a ton of adult turtles i would say...
