The Cebu Small Earthworm Eating Tarantula: A Beginner's Guide to Orphnaecus sp. Cebu
The world of tarantulas is vast and diverse, with species catering to every level of experience. For those seeking a truly unique and fascinating challenge in the medium-sized tarantula category, the Orphnaecus sp. Cebu (often referred to as the Cebu Earthworm Eater or Cebu Small) might be the perfect fit. This relatively small, fast-growing tarantula hails from the Philippines and is known for its unique diet in the wild, primarily consisting of earthworms. While they can be a bit more demanding than beginner-friendly species like the Grammostola or Brachypelma genus, with the right information and attention, you can successfully keep and appreciate this captivating creature.
What Makes the Cebu Small Special?
Unique Diet (in the wild): As the name suggests, Orphnaecus sp. Cebu are primarily earthworm eaters in their natural habitat. While they will readily accept more common feeder insects in captivity, their fondness for worms adds a unique element to their care.
Relatively Small Size: Unlike many massive tarantulas, the Cebu Small rarely exceeds 4-5 inches in leg span, making them manageable to house and handle (though handling is not recommended).
Enigmatic Behavior: While not overly defensive, the Orphnaecus sp. Cebu can be skittish and quick. They're known for their burrowing behavior and tendency to dart into hiding at the slightest disturbance.
Fast Growth Rate: Under optimal conditions, the Cebu Small can grow fairly quickly, especially when young, providing keepers with a rewarding sense of progress.
Beautiful Coloration: They boast a striking, dark brown or black coloration with subtle, almost iridescent hints of bronze or purple.
Setting Up Your Cebu Small's Home:
Enclosure: A terrestrial enclosure is a must. A 5-gallon aquarium or a similar-sized plastic container with adequate ventilation will suffice for an adult. Spiderling enclosures should be appropriate for their tiny size.
Substrate: A deep layer of substrate is crucial, as these tarantulas are avid burrowers. A mix of coco fiber, peat moss, and vermiculite provides excellent moisture retention and burrow stability. Aim for at least 4-6 inches of depth.
Humidity: Maintaining high humidity is essential. Target a humidity level of 70-80%. This can be achieved by regularly misting the substrate, especially the lower layers. Ensure adequate ventilation to prevent stagnant air and mold growth.
Temperature: The ideal temperature range is 75-85°F (24-29°C). This can be achieved with a low-wattage heat mat attached to the side of the enclosure, regulated by a thermostat. Avoid overheating.
Decorations: Provide a hide, such as a cork bark slab or a half log, to offer a sense of security and encourage burrowing. You can also add some fake plants to create a more natural environment.
Water Dish: Although they obtain moisture from their prey and the environment, a shallow water dish should always be available. Ensure it is shallow enough to prevent them from drowning.
Feeding Your Cebu Small:
Feeder Insects: While they are known for their love of earthworms, Orphnaecus sp. Cebu will readily accept crickets, roaches (dubia are a good choice), and mealworms.
Feeding Frequency: Spiderlings should be fed 2-3 times a week, while adults can be fed once a week.
Prey Size: Choose prey items that are appropriately sized for your tarantula. A good rule of thumb is to offer prey that is no larger than the tarantula's abdomen.
Earthworms: If you want to offer earthworms (which is highly recommended), ensure they are pesticide-free and appropriately sized. Cut the worm in half if too long.
Remove Uneaten Prey: Always remove any uneaten prey items after 24 hours to prevent them from stressing the tarantula or fouling the enclosure.
Important Considerations:
Venom: While the venom of Orphnaecus sp. Cebu is not considered medically significant, bites can be painful and may cause localized swelling and discomfort. Handle with caution and respect.
Defensive Behavior: Although not typically aggressive, they are known for their speed and skittishness. They may bolt if startled. Rehousing should be done with care, using a catch cup and long tongs.
Ventilation: Proper ventilation is crucial to prevent the build-up of stagnant air and harmful bacteria or fungi. Ensure adequate ventilation in your enclosure.
Molting: During molting, a tarantula will become more reclusive and refuse food. Do not disturb it during this time. Maintain appropriate humidity levels to aid in the molting process.
Is the Cebu Small Right for You?
The Orphnaecus sp. Cebu is a rewarding but demanding tarantula. They are not recommended for absolute beginners. If you have experience with tarantula keeping and are looking for a fascinating and unique species to add to your collection, the Cebu Small might be the perfect choice. By providing the appropriate environment and care, you can enjoy the beauty and captivating behavior of this fascinating earthworm-eating tarantula. Remember to research thoroughly and be prepared to dedicate time and attention to its specific needs. Good luck!
