Looks how to spot one
Hairy exoskeleton (tarantula)
One of the most colourful tarantulas: metallic blue legs, a blue-green carapace and an orange, hairy abdomen. The genus name itself refers to its colours.12
Personality what they are like
Generally calm but quick and a little skittish, and it rarely gets defensive unless really pushed. It has a strong feeding response and is out in the open more than many tarantulas.21
Daily activity how busy a day looks
A busy, active spider that spins thick silk tunnels and sheets all over its enclosure, so there is always something new to see.21
Grooming and care the hands-on bits
Provide a shallow water dish. Feed adults about every 2-3 weeks and wait 5-10 days after a moult before offering food. Let the top layer of substrate dry out between waterings.2
Home where they are happiest
A wider-than-tall enclosure at least 3-4 times its leg span, filled a third to a half with substrate, with plenty of anchor points for webbing. Keep it at about 20-24 C and moderate humidity, with mostly dry conditions.2
Food basics what goes in the bowl
Company who they like around
A solitary spider; keep one per enclosure.2
The story where it all began
Strand described it in 1907 from Venezuela, and it later received its own genus, Chromatopelma. In the wild it lives only on the dry Paraguaná Peninsula, where it webs its burrows under bushes and tree roots.1
