Chromatopelma cyaneopubescens, often called the Green Bottle Blue, is a tarantula prized for its vivid metallic coloration and relatively calm temperament. Native to Venezuela, this species combines manageable care needs with striking visual appeal for hobbyists who prioritize display animals.
With proper attention to enclosure design, diet, and long term maintenance, keepers can maintain healthy, active specimens that showcase their signature blue setae and energetic exploration. The following sections outline the most important aspects of Chromatopelma cyaneopubescens care in a practical, easy to follow format.
| Common Name | Scientific Name | Adult Size | Lifespan | Temperament |
|---|---|---|---|---|
| Green Bottle Blue | Chromatopelma cyaneopubescens | 4 to 5 inches leg span | 3 to 4 years female, 2 to 3 years male | Docile, fast, skittish when disturbed |
| Habitat Type | Arid scrub and savanna | Recommended Temp | Recommended Humidity | Activity Level |
| 24 to 27°C | 40 to 60 percent | Moderately active |
Enclosure Setup and Space Requirements
Vertical vs Horizontal Orientation
Chomatopelma cyaneopubescens adults are highly active runners and jumpers, so a taller rather than wider tank helps them feel secure. A standard 20 to 30 liter vertical enclosure with secure ventilation works well for most specimens.
Substrate and Furnishings
Use a deep layer of lightweight substrate such as a mix of peat, coco fiber, and perlite to allow burrowing while retaining slight moisture. Add cork bark, a lightweight hide, and a low climbing structure to encourage natural exploration without the risk of collapse.
Temperature, Humidity, and Climate Control
Heating Strategies
Maintain ambient temperatures between 24 and 27°C using a low wattage heat mat on one side of the enclosure, regulated by a thermostat. Avoid placing heat sources directly under heavy hides where temperatures can spike.
Humidity Management
Keep humidity in the 40 to 60 percent range by light misting every few days and offering a small, shallow water dish. Ensure there is adequate airflow to prevent stagnant conditions that can lead to mold or respiratory stress.
Feeding Schedule and Dietary Considerations
Appropriate Prey Size
Feed adults once every 7 to 10 days with insects such as crickets or roaches that are about the size of the tarantula’s abdomen. Offer prey on the substrate or on a low platform to minimize the need for fast aerial pursuit.
Nutritional Variety
Rotate prey species and occasionally include gut loaded variants to provide a broader nutrient profile. Dust feeders lightly with a calcium and vitamin supplement every third or fourth feeding to support long term exoskeleton health.
Handling, Observation, and Longevity Factors
Behavioral Cues and Safety
Chomatopelma cyaneopubescens is generally docile but fast and prone to running if startled. Observe activity patterns during the evening, and avoid handling, as their setae can irritate skin and their rapid movement increases handling risks.
Long Term Maintenance
Plan for regular cleaning of the water dish, removal of uneaten prey, and partial substrate changes every few months. Monitor for changes in coloration, activity, or web quality, as these can indicate stress, improper humidity, or underlying health issues.
Key Takeaways for Long Term Success with Chromatopelma cyaneopubescens
- Provide a vertical oriented enclosure with secure ventilation and adequate height.
- Use a deep, mixed substrate and maintain humidity between 40 and 60 percent.
- Keep temperatures stable between 24 and 27°C using regulated heat sources.
- Feed appropriately sized prey regularly, ensuring nutritional variety and occasional supplementation.
- Observe behavior and appearance regularly, limiting direct handling to reduce stress and risk of urtication.
FAQ
Reader questions
How often should I molt my tarantula and what signs indicate a problem during molting?
Tarantulas molt as they grow, and younger specimens may molt every few months while adults molt once or twice per year. Signs of problems include incomplete sheds, curling legs, or prolonged refusal of food after molting, which may require adjustments in humidity and hiding spots.
Can I keep more than one Chromatopelma cyaneopubescens in the same enclosure?
Keeping multiple Green Bottle Blues together is not recommended due to their moderately active nature and the risk of cannibalism, especially when space or food resources are limited.
What should I do if my tarantula suddenly becomes very defensive or starts urticating?
Reduce handling, provide more hides, and check for correct temperature and humidity ranges. If urticating continues, ensure the enclosure is placed in a low traffic area and avoid sudden movements near the tank.
What lighting and photoperiod do Green Bottle Blues prefer?
They do not require special lighting; a natural room light cycle of roughly 8 to 12 hours is sufficient. Avoid bright, constant lights that can stress the tarantula and disrupt its behavior.
