Prevue Pet Products Bpv1143 5-Inch Bird Cuttlebone, Medium

The cuttlebone arrived intact for me. I took the metal piece off and put a chunk of the bone in my aquarium. I got my snail with a cracked shell and wanted to prevent further damage. I definitely recommend only putting a small chunk in the water. Overtime the water of the tank breaks down the bone. I was surprised to receive such a large piece for the low price! Mine arrived with no cracks, but I was planning on breaking it into chunks anyways. This is a good source of calcium for aquatic life and birds! Shipping was fast as well. The piece I got was white, but if you see any yellow coloring remember it is from a living thing, so it will not be perfect.
