Peruvian Cobalt Red Rump Tarantula, Thrixopelma cyaneolum “Blue”

The Cobalt Red Rump Tarantula, Thrixopelma cyaneolum “Blue” is an uncommon large dwarf (4.5 to 5") New World terrestrial tarantula prized for its smoky cobalt-blue coloration, reddish abdominal tones, and calm overall demeanor. Native to Peru, this species develops velvety blue-gray hues that intensify after molts, giving mature specimens a striking metallic appearance under natural light.

Unlike many defensive or overly reclusive species, the Cobalt Red Rump Tarantula is often visible near its hide and tends to display steady, deliberate behavior. Its manageable temperament and hardy care requirements make it an excellent choice for keepers looking to expand beyond common beginner species while still avoiding the challenges of more defensive Old World tarantulas.

This beautiful dwarf species thrives in a terrestrial enclosure with moderate humidity, good ventilation, and slightly moist lower substrate layers. Adults typically reach around 4.5–5 inches in leg span and are known for moderate growth rates and reliable feeding responses.

Whether you are building a diverse South American tarantula collection or searching for a unique display species with understated beauty, Thrixopelma cyaneolum “Blue” stands out as one of the hobby’s hidden gems.
