Cichlid Zone - African Cichlids - South American Cichlids: using coconut shells - Cichlid Zone - African Cichlids - South American Cichlids

Hi I am new here. I have read that some people use coconut shells cut in half with small holes drilled into them...especially for breeding Kribs. does anyone know what you need to do to prep the shell? Or where one might purchase some tank ready? any help will be appreciated. thanks
