CUTTLEBONE Australian Cuttlefish Bone 4 Medium (12cm) or 5 Small (8-10cm)

The Australian Cuttlefish Bones offered by Aquarzon are in almost whole pieces.

QUANTITY & SIZE: 4 pieces Medium (around 12cm) or 5 pieces Small (around 8-10cm)


These are 100% natural and very clean. These are not imported. 

These have been manually washed and dried without the usage of chemicals.

If you are using this for aquarium purposes (such as for Mystery Snails, shrimp & fish), 1 piece can lasts for around 2-3 months so 4-5 pieces will last around 1 year if you use one by one. This is great value.



Cuttlebone is the the cuttlefish's "internal shell" which is naturally made up of mostly calcium carbonate (CaCO3) in the form of aragonite and other trace minerals including zinc, potassium and iron. 

The calcium contained has a bioavailability rate of 100% and best of all, it is natural and gradually utilised in an aquarium environment. 

It is be very beneficial for:

- Mystery snails, ramshorn snails and other pet snails (to provide calcium, strengthen their shells and prevent cracked or damaged shells)

- Aquarium cherry, crystal and other shrimp (to provide calcium, strengthen their shells and prevent moulting issues)

- Fish (to provide calcium and trace minerals)

- Plants (can be placed into aquarium substrate to provide calcium, potassium, iron, zinc, etc.)


This item qualifies for free Australia Post Express for orders $90 and above (can be combined with plants in the same order).
