Guatemalan Red Rump Tarantula
Tliltocatl sabulosus (formerly Brachypelma sabulosum)
1. Deep Soil & Low-Ceiling Safety Setup
2. Two Great Ways to Set Up Your Habitat
Sizing the Tank: Slings vs. Adults
Putting a fingernail-sized baby ('sling') in a giant 10-gallon tank makes it impossible for them to find dinner:
Option A: Spiderlings ('Slings' Under 1.5")
Keep in a vented sling vial or micro acrylic cube (about 3–4× their legspan wide) with 2" of soil, a piece of moss, and a clean tattoo-ink cap or bottlecap for water.
Option B: Juveniles & Adults (2" to 7"+)
A 5- to 10-gallon glass or acrylic enclosure filled halfway up with 4–6" of packed reptile/invertebrate soil and a curved cork bark starter cave.
Ground Burrowers vs. Tree Climbers
Make sure your setup matches where your spider actually lives in nature:
Option A: Ground / Burrowing (Curly Hair, Red Knee, Arizona Blonde)
Wide floor space, deep 4–6" soil for bulldozing, and low ceiling clearance so a clumsy climber can never take a big fall.
Option B: Tree-Dwelling (Pinktoes, Versicolor, Jumping Spiders)
Tall enclosure with lots of side-wall air holes (cross-ventilation!) and tall cork bark reaching near the ceiling.
To Handle or Not to Handle?
Real talk from our invert team: tarantulas don't get cuddly from being held—handling is mostly for us:
Option A: Hands-Off Display Pet (What We Recommend)
Safest for the spider! Use a soft paintbrush to gently tap their back legs and guide them into a catch-cup whenever you need to clean.
Option B: Sit Flat on the Floor (Calm Docile Species Only)
If you do let a calm Curly Hair or Red Knee walk on your open palm, sit on the floor or bed so a sudden bolt can never mean a fatal drop to the floor.
3. Feeding by 'Booty Size' & The Molting Rule
Best Bugs & Big No-Nos:
Top pick—nutritious and won't bite a spider!
Great hunters—MUST remove uneaten crickets after 24h!
Crush worm heads so they can't hide underground
Wild bugs carry lawn sprays & parasites that kill spiders
4. Four Keys to a Happy, Thriving Guatemalan Red Rump Tarantula
Watch Out for Wire Mesh
Heavy ground tarantulas have two tiny hooks on each foot that can get snagged in cheap woven window-screen lids. Acrylic lids with drilled air holes are way safer!
Overflow the Water Dish
Tarantulas hate being sprayed in the face with a mister! Instead, just overfill their water dish a little bit once a week so one corner of the soil stays damp.
Itchy Belly Hairs
New World tarantulas kick itchy 'urticating hairs' off their butt when annoyed. Don't rub your eyes after working in the tank, and wash your hands with soap!
Upside-Down vs. Death Curl
Flat on their back = happy molting! Right-side-up with all 8 legs curled tightly *underneath* the belly = dehydrated ('death curl')—put their mouthparts right into a shallow puddle of water!

Why We Love Them: The Guatemalan Red Rump is a gorgeous, heavy-bodied tarantula. As their name suggests, they have a jet-black body accented by a large patch of fiery red hairs on their abdomen. Their incredibly docile temperament, slow speed, and hardiness make them an absolutely perfect choice for a first-time tarantula owner.
Safety Information
Venom/Defense: Their venom is medically insignificant. They are generally considered one of the calmest species in the hobby. If startled, their first line of defense is usually to kick a small cloud of urticating hairs rather than bite.
Handling Precautions: While they are famous for being handleable, all tarantulas are fragile. Because they are heavy-bodied terrestrials, a fall from a human hand to a hard floor will rupture their abdomen and kill them instantly. If you must handle them, always sit on the floor or hold them directly over a soft surface (like a bed).
Housing & Enclosure
Enclosure Type & Size
- Type: Terrestrial / Opportunistic Burrower.
- Minimum: A 5-gallon to 10-gallon glass aquarium or an Exo Terra Low (18x18x12) is perfect for an adult.
- The Height Warning (CRITICAL): You must prioritize floor space over vertical height. If the enclosure is too tall, you must fill it with deep substrate so the distance from the dirt to the ceiling is no more than 1.5x the spider's leg span. A fall from the ceiling is fatal.
Substrate
- Recommended: Coconut fiber (Eco Earth), peat moss, or organic topsoil.
- Depth: Provide 3 to 5 inches of substrate. They will occasionally dig starter burrows, and the deep soil cushions them if they climb.
Décor & Enrichment
- Hides: Provide a curved cork bark hide or half-log to help them feel secure.
- Water Dish: Provide a shallow water dish. Keep it filled with fresh water at all times. Do not put sponges in the water; tarantulas cannot drink from sponges and they harbor bacteria.
Temperature
| Zone | Temperature |
|---|---|
| Ambient | 70–82°F (21–28°C) |
- Heating: Room temperature is perfect. If you are comfortable in a t-shirt, your tarantula is comfortable. Never use a heat lamp.
Humidity
- Target Range: 65–75% (Moderate).
- How to Maintain: Maintain a moisture gradient. Overflow their water dish once a week to keep the soil immediately around the dish slightly damp. Allow the other half of the enclosure to remain completely dry. Ensure the enclosure has good cross-ventilation.
Diet & Nutrition
Like most of the Tliltocatl genus, they are excellent, eager eaters with a moderate growth rate.
Primary Diet
- Live crickets, dubia roaches, or mealworms. Ensure the prey is smaller than the spider's abdomen.
Feeding Schedule
| Life Stage | Frequency | Prey Size |
|---|---|---|
| Spiderling (Sling) | Every 5–7 days | Pinhead crickets or small mealworms |
| Juvenile | Every 7–10 days | Medium crickets |
| Adult | Every 10–14 days | 2-3 Large crickets or 1 Large Roach |
Pre-Molt Fasting
- If they seal the entrance to their hide with webbing and dirt, and refuse food, they are in pre-molt. Do not disturb them.
Molting
During the Molt
- DO NOT disturb the spider. It will flip on its back to molt. It is not dead. Do not flip it over.
- Remove any live crickets from the enclosure immediately. A live cricket will eat a molting tarantula alive.
Post-Molt Care
- Wait at least 10–14 days before offering food. Because they are heavy-bodied, it takes a long time for their new fangs to harden. If they bite a cricket too soon, their fangs will break off and they will starve to death.

How We Keep Them at Critter Cabana & Gresham Pet Supply
- Oregon Winter Furnace Air vs. Molting Humidity: When Pacific Northwest furnaces kick on from October through April, indoor room humidity drops fast and dries out small enclosures from the top down. Rather than misting the spider or invert directly (which stresses terrestrial species and invites stagnant mold), we keep Guatemalan Red Rump Tarantula at
65-75% (Moderate)by using a deep moisture-retaining substrate bed (ReptiSoil + Coco Fiber + Sphagnum Moss), overflowing the water dish slightly into one corner, and maintaining cross-ventilation. - Safe Room Heating in the Willamette Valley: If your house drops below 65°F on winter nights, never stick a heat pad on the bottom of a burrowing invertebrate tank—they dig down to escape heat and will cook themselves. Use a low-wattage side-mounted heat mat on a digital thermostat or warm the room ambiently to
species-appropriate warm zone. - Stocked at Newberg & Gresham: At Critter Cabana (Newberg) and Gresham Pet Supply, we stock acrylic and glass invertebrate enclosures, cork bark flats and tubes, bioactive substrates, flightless fruit flies (D. melanogaster and D. hydei), pinhead to adult crickets, dubia roaches, and live Temperate White Springtail and Isopod cultures.
Common Questions (FAQ)
How do I keep my Guatemalan Red Rump Tarantula warm and humid enough during an Oregon winter?
Target species-appropriate warm zone and 65-75% (Moderate). When Oregon winter furnaces dry out the air, use a deep 3–5 inch substrate mix of Zoo Med ReptiSoil and coco fiber, keep a shallow water dish filled, and dampen one corner of the substrate rather than misting the animal directly. Never put a heat mat underneath a burrowing invertebrate enclosure.
What size enclosure does a Guatemalan Red Rump Tarantula need?
An adult Guatemalan Red Rump Tarantula thrives in 5 to 10-Gallon Tank with secure ventilation. For terrestrial tarantulas and scorpions, floor space and deep substrate matter most (keep open fall height low so heavy-bodied species cannot rupture their abdomen); for arboreal species, prioritize vertical cork bark tubes and cross-ventilation.
Can I put isopods in a Guatemalan Red Rump Tarantula bioactive enclosure?
Around molting tarantulas and scorpions, skip protein-hungry large isopods and stick to Temperate White Springtails (or gentle Dwarf White isopods in humid detritivore setups) so a soft, newly molted animal is never nibbled.
Where can I find Guatemalan Red Rump Tarantula, cork bark, and feeder insects in Oregon?
