Megaphobema robustum – Colombian Giant Redleg Tarantula

The Colombian Giant Redleg is a striking New World terrestrial with a heavy build, bold reddish legs, and a unique defensive personality that makes it unforgettable. This species is known for its size, attitude, dramatic threat displays, and impressive presence, making it a standout tarantula for keepers who enjoy large, powerful terrestrials with real character.

Special Notices
Setup notes This is a large, heavy-bodied terrestrial tarantula, so I keep the enclosure low, secure, and practical. Give it floor space, a sturdy hide, moderate substrate depth, and no excessive climbing height. A fall can be dangerous for a spider this big.
Keeper note Megaphobema robustum is best treated as a hands-off display tarantula. This species can be nervous, defensive, and surprisingly dramatic when disturbed, sometimes turning to present its rear legs or kicking hairs when it feels pressured.

🧰 Care Details
🌡️ Temperature 75–82°F (24–28°C). Warmer temperatures usually mean faster growth because they molt more often, but I prefer steady, moderate warmth for this species instead of pushing extreme heat.
💧 Humidity Aim for about 75–80% inside the enclosure with good ventilation. Keep part of the substrate lightly moist, especially for babies and juveniles, but avoid swampy substrate, stale air, or long-term bone-dry conditions during molt. Water dishes are optional; I usually skip them except for larger species.
🏠 Housing
🏠 Babies Use a 1–4 oz deli cup with needle ventilation. Add enough substrate for security, plus a tiny hide or starter burrow. Keep one section lightly moist without soaking the cup. FREE container at checkout IF requested; not included otherwise.
🏠 Juveniles Larger specimens should be kept in an enclosure around 2–3x body size, flexible by the individual. Give juveniles floor space, a secure hide, moderate substrate depth, and good airflow. They appreciate cover and can be more comfortable when the setup feels snug and secure.
🏠 Adults Adults need a secure terrestrial enclosure with generous floor space, a sturdy hide, and enough substrate to cushion the spider and support light digging. Keep the height conservative because adult Colombian Giant Redlegs are large, heavy tarantulas that should not have a long fall.
General Diet
🍽️ Feeding Crickets + roaches work great, especially Dubia, Red Runner, and Lobster roaches. Babies should get baby crickets or baby roaches. If prey is too big, pre-kill by crushing the head, leave it, then remove leftovers or bolus. Occasional treat for super large specimens: pinky/hopper mouse or feeder lizard very sparingly; excess calcium can cause constipation/pooping issues. We never use pinhead crickets because they do not provide enough protein.
In-depth Facts
🕷️ Latin name / Scientific name Megaphobema robustum
📛 Common name(s) Colombian Giant Redleg Tarantula, Colombian Giant Red Leg, Giant Redleg Tarantula.
🌡️ Temperature 75–82°F (24–28°C), with stable warmth and no extreme heat spikes.
💧 Humidity About 75–80% inside the enclosure. Keep the substrate lightly humid with airflow, avoiding both swampy conditions and long-term bone-dry substrate.
📍 Locale Colombia. I keep this species like a humid South American terrestrial: secure, well ventilated, lightly humid, and never wet or stagnant.
🏷️ Category New World terrestrial; large, defensive when stressed, opportunistic burrower with dramatic threat displays, urticating hairs, and powerful rear-leg defensive behavior.
📏 Size Females commonly reach about 6.5–8 inches DLS; males are usually smaller and leggier, around 5–6 inches DLS. Max size is typically around 8 inches DLS with a broad, powerful build.
🪶 Urticating hairs Yes. This New World terrestrial can kick urticating hairs when stressed. It may also turn, posture, or use its rear legs defensively, so I recommend using tools during maintenance and keeping handling to a minimum.
⏳ Growth rate Medium. This species is not as fast as some giant terrestrials, but babies and juveniles grow steadily with consistent feeding, proper moisture, and stable temperatures because warmer conditions usually mean more frequent molts.
🧭 Life span Females commonly live around 15–20+ years with good care; males usually live about 4–6 years.
🍽️ Feeding Usually a solid eater once settled, though some individuals may be cautious after a move. Offer appropriately sized crickets or roaches near the hide entrance and remove uneaten prey or bolus. Avoid overfeeding heavy-bodied specimens.
🎯 Recommended levels Great for lovers of large, dramatic New World terrestrials who want a unique species with size, attitude, and impressive red-legged presence. Best for keepers comfortable with urticating hairs, defensive displays, and a confident hands-off maintenance style.

⚠️ Safety Disclaimer

Safety Disclaimer: Tarantula bites are extremely rare, and there are no recorded human fatalities. Venom strength varies by species; Old World tarantulas are usually more potent than New World tarantulas, with Poecilotheria known for especially strong venom. Larger tarantulas may also deliver more venom.

If bitten, stay calm. Most symptoms fade within minutes to hours, though potent species may cause discomfort for up to a week. In 13 years, I’ve only been bitten once, and symptoms were gone after one week.

Handling is at your own risk. I’m not responsible for bites or injuries. Always prioritize your safety and the tarantula’s well-being.
