Green Bottle Blue Tarantula

The Green Bottle Blue Tarantula (Chromatopelma cyaneopubescens) is a hardy, fast‑growing New World species that thrives in a dry, well‑ventilated enclosure. A 5–10 gallon tank or similar‑sized terrarium works for an adult, with more floor space than height to reduce fall risk. Provide several inches of dry substrate (like a mix of coco fiber and sand) with a hide, anchor points for webbing, and a shallow water dish. Keep temperatures around 75–82°F with good airflow and low to moderate humidity, allowing the substrate to stay mostly dry and using a water dish and occasional light misting to prevent it from becoming too arid.

This species is generally skittish and very fast, so it’s best appreciated as a display animal rather than handled. They can flick urticating hairs when stressed, so always work calmly and gently in the enclosure and avoid direct contact when possible. Feed appropriately sized crickets, roaches, or other feeder insects 1–2 times per week for juveniles and about once a week or slightly less for adults, removing any uneaten prey after 24 hours. Watch for signs of premolt (reduced appetite, dull coloration, increased webbing) and avoid feeding or disturbing the spider while it is molting and for several days afterward.

Basic care bullet points:

• Enclosure size: ~5–10 gallon equivalent, more floor space than height.

• Substrate: Several inches of mostly dry substrate (coco fiber/sand mix works well).

• Hide & decor: Provide at least one hide plus branches or decor for webbing.

• Temperature: Aim for ~75–82°F (24–28°C); avoid extreme heat or cold.

• Humidity: Relatively low; keep substrate mostly dry, with a water dish and light, occasional misting if needed.

• Water: Shallow, always‑available water dish; keep it clean and filled.

• Feeding: Crickets/roaches sized to the spider’s body; juveniles 1–2x per week, adults about weekly.

• Handling: Avoid regular handling—very fast and can kick irritating hairs.

• Molting: Do not feed or disturb during and right after molts; wait until fangs are fully darkened.

• Cleaning: Spot‑clean leftover food and waste; full rehousing every 6–12 months or as needed.
