Cyriopagopus lividus - Cobalt Blue Tarantula

Discover the striking beauty of the Cyriopagopus lividus, more popularly known as the Cobalt Blue Tarantula. This species is a favorite among tarantula enthusiasts for its vibrant blue hue, which makes it a standout in any collection. The Cobalt Blue is not just about looks; it's also known for its intriguing behavior and secretive nature, providing a unique challenge and reward for experienced keepers.

Care Details

  • Temperature: Ideal range for most tarantulas is 75 to 85°F (24 to 29°C). Tarantulas in warmer environments eat more, grow faster, and molt quicker.
  • Humidity: The Cyriopagopus lividus thrives in a humidity range of 75-85%. Water dishes are not necessary, but they pose no harm if used. I personally do not use them.
  • Housing: Young Cobalt Blues should be housed in small vials up to 5 inches tall and 2 inches in diameter, with ample ventilation. For juveniles larger than 2 inches, a 7-8 inch tall enclosure is appropriate, and for adults, an enclosure ranging from 12 to 16 inches in height is recommended. Remember to request your free vial at checkout, as it won't be included unless specified.


I personally provide a variety of crickets and cockroaches, including Dubia, Red-runner, Lobster, and Madagascar hissing roaches. For baby tarantulas, baby crickets and baby roaches are ideal. If a small enough cricket or cockroach is unavailable, simply crush its head and leave it in the enclosure; your tarantula should handle the rest. It's important to remove any uneaten food to prevent mold growth. An occasional treat, such as a pinky or hopper mouse, adds a nice variety to their diet, though these should be given sparingly to avoid excessive calcium intake.

Safety Disclaimer:

Experiencing a tarantula bite is an extremely rare occurrence, and it's important to note that there have been no recorded fatalities due to a tarantula bite. The venom potency varies across species, with Old World tarantulas generally having stronger venom than their New World counterparts. Within the Old World category, the Poecilotheria genus is known for having particularly potent venom.

It's crucial to approach tarantulas with respect and understanding. If you happen to get bitten, which is unlikely, the key is to stay calm. In most cases, the discomfort is superficial and subsides within a few minutes to a few hours. However, bites from species with more potent venom may result in symptoms lasting up to a week. Remember, larger tarantulas tend to have more venom than smaller ones.

Please be aware that I cannot assume responsibility for bites. Tarantula handling should be done at your own risk. In my 11 years of experience with these creatures, I have only been bitten once, by a species with highly potent venom. While the experience was painful, the symptoms had completely disappeared after a week.

Handle tarantulas responsibly, and always prioritize your safety and the well-being of the tarantula.
