Chromatopelma Cyaneopubescens - Green Bottle Blue Tarantula (Sling)

Green Bottle Blue Tarantula (Chromatopelma cyaneopubescens)

The Green Bottle Blue Tarantula is a true showstopper, prized for its electric blue legs, vivid green carapace, and fiery orange abdomen—colours that intensify with every moult. Even more impressive is its extreme webbing behaviour, creating dense silk tunnels and dramatic displays that turn any enclosure into a visual masterpiece.

Hardy and adaptable, Chromatopelma cyaneopubescens thrives in dry, well-ventilated setups and rewards keepers with a bold feeding response, active presence, and fast growth. Naturally skittish but not aggressive, it's best enjoyed as a hands-off display species, perfect for observation and photography.

Why keepers love the GBB:

• One of the most colourful tarantulas in the hobby

• Heavy webber—ideal for display enclosures

• Hardy and low-maintenance when housed correctly

• Females can live 12–15+ years

Best for: Display-focused keepers and tarantula enthusiasts
