About this Fella
Yellow Fat-Tail Scorpion for sale from Big Z's (Androctonus australis). Spice-rated keeper notes, care guidance, and live-arrival packing where eligible.
The fat-tail. One of the most dangerous scorpions kept.
Androctonus australis, the Yellow Fat-Tail, is the North African buthid with the thick, heavy tail the name describes, and one of the scorpions responsible for serious stings across its range. These arrived at 2 to 3 inches.
Spice Level 5: Extreme. Medically significant venom. Display only, no handling, double containment, tongs and a catch cup for every service, and a keeper who already keeps hot buthids. Dry sand and stone, a small dish, heat. Check local legality before ordering; a sting needs professional medical care. Read the Big Z's care guide before it arrives.
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 →

Fat-Tailed Scorpions
Big Z's Quick Verdict: Among the deadliest scorpions in the world: aggressive, fast-striking, lethal venom, responsible for human fatalities. Serious hot-keeper territory only, with legal authorization and an antivenom-access plan. Adults reach about 3.5-5 in.

Use This Guide Safely
Confirm the exact animal. Match this guide to the species, locality, size, and life stage on your label. If the ID is uncertain, use the more conservative part of the range and ask before changing the setup.
Change one thing at a time. Treat temperature and humidity as target zones, then watch posture, burrowing, drinking, feeding, and molt behavior before making another adjustment.
Respect the handling boundary. If the guide says no handling, fast, defensive, or medically significant, plan transfers with catch cups, locked lids, and no bare hands. For serious bites, stings, or symptoms, seek emergency medical care.

Medically significant, lethal venom. Documented human fatalities. Aggressive and fast to strike.
Hot-keeper only: antivenom-access planning and, in many places, a permit.
Strict no-contact. Secondary containment, long tools, never an open-table transfer.
Escape risk. The enclosure must be sealed and the animal locatable before you open it.
Tiny ventilation, placed low and plentiful. A sealed hot box traps damp air, and mold is the quiet killer of arid buthids.
Care Basics
Hot, dry, deep sand with a tight hide.
Tiny ventilation, but plenty of it, low on two opposite walls so air crosses the sand.
Shallow water dish with pebbles so tiny instars cannot drown.
Never handle, under any circumstance.
Maintenance is slow, planned, and tool-based with a catch container, every time.
Feeding, Growth & Maintenance
Appropriately sized crickets or roach nymphs, body length or under, smaller for instars. Young every 4-7 days, adults roughly weekly to every other week.
Drop prey with long tongs over a catch container, never on an open desk.
A live-bearer: the mother carries first-instar young on her back. A carrying female must not be disturbed.
Matures over several molts. Clear out every feeder when it stops eating and tucks away, and don't disturb a fresh, pale molt until it hardens.

Advanced Keeper Notes
Enclosure & Microclimate
North Africa and the Middle East, extreme arid. Hot, dry, deep sand for burrowing, a tight hide, minimal clutter.
Day temps 80-95°F with a cooler night drop. The enclosure must stay sealed and the animal locatable before you open it.
Use many tiny vents low on two opposite walls, at the sand line, so air crosses the layer it burrows into. Still, damp air under the hide grows fungus even in a desert setup.
Heavy airflow holds ambient at 25-40% with no effort. The water dish is the only moisture input, you cannot over-ventilate it.
Keep the dish shallow, packed with pebbles or coarse grit so the waterline sits below the rim. Site it away from the hide.
Feeding, Growth & Maintenance
Appropriately sized crickets or roach nymphs, body length or under, smaller for instars. Young every 4-7 days, adults roughly weekly to every other week.
Drop prey with long tongs over a catch container, never on an open desk.
A live-bearer: the mother carries first-instar young on her back. A carrying female must not be disturbed.
Matures over several molts. Clear out every feeder when it stops eating and tucks away, and don't disturb a fresh, pale molt until it hardens.
Possible Origin / Range
Likely native range: North Africa and the Middle East: extreme arid desert.
Habitat translation: A hot, dry, deep-sand enclosure with a tight hide and minimal clutter: sealed, simple, and never handled.
Advanced Keeper Details
Adult size about 3.5-5 in. Some Androctonus species are documented in human fatalities, among the most dangerous scorpion genera kept anywhere.
For serious hot-keepers with a local antivenom-access plan and, in many places, the required permit. Verify legal status before acquiring.
The usual path: years with milder buthids first, then a legal review, then this. Never as an early scorpion.

Beautiful spider who arrived in excellent condition! My family and I are very happy with the professional and honorable service we received from this business. As such, we would like to recommend them to other potential customers.
Love my grossa! Such a beautiful species, and I have zero complaints about Big Zs tarantulas! They really are one of the best, from packaging to making sure you have everything you need for your new addition, including enclosures and clean up crew. I couldn’t be happier and will definitely be purchasing from again.
Unfortunately arrive dead but was packaged very nicely and seller kindly helped me with what to do next. Unfortunate events mostly due to weather, but otherwise will be buying from again.

The shipping price was very reasonable for the kind that’s required for these kind of items. Packaging was great; there was a cooling gel and everything else required to keep it safe. Item as described and would do business with them again!
