- Mist occasionally, but don’t allow the substrate to become soggy
Water

Feeding Your Monocentropus balfouri
- Offer live prey such as crickets, roaches, and mealworms
- Juveniles: Feed every 3–5 days

- In a communal setup, drop multiple prey items to avoid food-based aggression
Feeding Tip: Drop food in different areas of the enclosure to ensure all individuals get access.
Communal Setup Guide
Unlike most tarantulas, M. balfouri can be successfully kept communally under the right conditions:
Key Tips:
- Start with spiderlings from the same sac
- House in a large enclosure with multiple hides
- Provide excessive webbing material and anchor points
- Monitor for bullying or cannibalism, especially during feeding or post-molt
Note: While communal keeping is possible, it still carries risk and is not recommended for novice keepers.
Temperament & Handling
- Speed: Very fast and skittish
- Defensive Behavior: Will bite if cornered; known to threat pose quickly
- Handling: Strongly discouraged due to speed and venom potency
M. balfouri is best appreciated from behind the glass—its beauty and webbing make it a true display species.
Molting & Growth
- Fast-growing species, especially when well-fed
