All-Natural Cuttlebone Combo Pack (6" & 10") | Reptile & Bioactive Calcium Supplement

Support your reptiles' skeletal health and give your bioactive clean-up crew an essential mineral boost with pure, unprocessed cuttlebone. This natural, slow-release calcium source allows tortoises, aquatic turtles, and terrarium invertebrates to safely self-regulate their mineral intake on demand.

In captivity, nutritional metabolic issues and beak overgrowth present ongoing challenges for chelonians and herbivorous reptiles. Natural cuttlebone serves a critical dual purpose: the soft, mineral-dense aragonite structure supplies bioavailable calcium carbonate without synthetic binders, while the firm, chalky texture naturally conditions and files down tortoise and turtle beaks during grazing. In humid bioactive enclosures, cuttlebone acts as a long-lasting, mold-resistant grazing block for isopods, millipedes, and snails, providing the raw minerals necessary to build and repair sturdy calcified exoskeletons.

What’s Included

• 1 × 6" Natural Cuttlebone: Compact size for isopod culture bins, micro-gecko vivariums, and juvenile turtle tanks.
• 1 × 10" Natural Cuttlebone: Heavy-duty block for tortoises, large aquatic basking platforms, and large communal displays.

Key Features & Husbandry Benefits

• Free-Choice Calcium Regulation: Allows tortoises, turtles, and breeding lizards to intuitively graze when their bodies require calcium, reducing the risk of metabolic deficiencies and egg-binding.
• Beak Conditioning: The micro-abrasive texture naturally trims chelonian beaks (rhamphotheca) during chewing, preventing painful overgrowth.
• Bioactive Custodian Nutrition: Provides a dedicated calcium reserve that prevents isopods from cannibalizing molts or chewing on delicate live plants.
• 100% Additive-Free: Naturally harvested, sun-bleached, and desalted with zero artificial binders, dyes, flavorings, or chemical preservatives.

Recommended Species & Uses

• Tortoises & Box Turtles: Russian, Greek, Hermann’s, Red-Foot, Sulcata, and North American Box Turtles (place dry on a feeding slate or substrate).
• Aquatic Turtles: Sliders, Cooters, and Painted Turtles (floats naturally at the waterline or wedges onto basking docks).
• Bioactive Invertebrates: Isopods (Armadillidium, Porcellio, Cubaris), land snails, and springtails.
• Lizards & Geckos: Leave small broken pieces in female gecko habitats or grate with a microplane for a fine, pure dusting powder over greens and live feeders.

Directions for Use

• Dry Terrariums: Place the cuttlebone soft-side up directly on a slate tile, feeding stone, or dry area of the enclosure floor to keep it clean and accessible.
• Aquatic Habitats: Drop the cuttlebone directly into the water (it will float for easy nibbling) or wedge a section into the basking area.
• Bioactive Setups: Snap into 1–2 inch pieces and bury them partially under the leaf litter directly in active isopod feeding zones.
