Socotra Island Blue Tarantula for sale from Big Z's (Monocentropus balfouri). Spice-rated keeper notes, care guidance, and live-arrival packing where eligible.
Powder-blue baboon, and the spider that raises its kids together
Monocentropus balfouri, the Socotra Island Blue, comes from one of the strangest places on Earth, the alien-looking island of Socotra off Yemen. It is a soft powder-blue and tan baboon spider, smaller than most, and it has a trick no other tarantula reliably pulls off: it is genuinely communal.
Raised together as siblings, balfouris cohabit peacefully, share webwork, and, remarkably, the mother tends her slings in the burrow rather than treating them as snacks. A small colony of these in one enclosure is one of the coolest displays in the hobby. Defensive but usually retreats; dry, easy care. The care guide covers the communal setup and the no-handling line (Old World venom is no joke).
The numbers live in the care guide. Enclosure size, temps, humidity, feeding schedule, premolt signs, handling boundaries: it's all in the care guide for this exact fella. Start with the full Advanced guide, or click for the quick Open the Simple version →

Burrow Buddy fits the listed juvenile size, but the animal may outgrow it at around 1.5" DLS. Plan for larger adult terrestrial (it makes a great small communal); matures near 4–5" DLS. Ask Big Z if you need help choosing the next enclosure.
