Care Guide
Tapinauchenius cupreus
Orange Tree Spider - a complete husbandry sheet. Use as a starting point and adjust to your individual specimen.
What size enclosure does an Orange Tree Spider Tarantula need?
Adults
25 × 25 × 40 cm tall with tight cross-ventilation - they are small arboreals that exploit every gap. Double-check lid clasps.
Slings & Juveniles
Small tall vials or arboreal sling tubs with a piece of vertical cork. Upgrade as they grow - arboreal slings do best slightly cramped, not in cavernous tanks.

What temperature and humidity does an Orange Tree Spider Tarantula need?
Heating
The Orange Tree Spider is comfortable at 24-28 °C. Most UK homes sit in or near this range for most of the year; heat the room rather than the enclosure if winter drops below it.
Humidity
75-85 % with strong airflow. Being tiny, they dehydrate fast - dampen the upper cork, not the floor, and never skip the water dish.
Ventilation
The single most important husbandry factor for this species. Cross-flow (top + side mesh) is non-negotiable - stagnant air causes mould, mites and failed moults.
What substrate is best for an Orange Tree Spider Tarantula?
Recommended Mixes
Depth
3-5 cm
Notes
Substrate is mostly a moisture buffer - arboreals live above it. Keep one corner lightly damp, never wet throughout.
How do you set up an Orange Tree Spider Tarantula enclosure?
Décor
The Hide
A vertical cork tube or propped bark retreat positioned up off the floor - the higher the retreat, the more the spider uses it.
Water
Shallow dish on the floor. Even dedicated canopy dwellers descend to drink - keep it full and clean.
Lighting
Ambient room light only. Avoid basking lamps - they desiccate arboreal species quickly.
How often should you feed an Orange Tree Spider Tarantula?
Good Feeders

Is my Orange Tree Spider Tarantula dying or moulting?
Pre-moult signs to look for
Refusing food for weeks is normal before a moult - an healthy Orange Tree Spider Tarantula fasting is almost never an emergency in itself. Watch for slowing down and spending more time in the hide, thickening the silk hammock it sleeps in. New World species like this one often show a bald spot on the abdomen that darkens to near-black as the new skin underneath readies - a darkening bald patch is a reliable countdown, not a disease.
On its back is MOULTING, not dying
An Orange Tree Spider Tarantula lying upside down or on its side with legs curled inwards is almost certainly mid-moult. Do not touch it, do not right it, do not mist it - just remove any live prey (crickets can kill a defenceless moulter) and leave the room.
How long between moults?
For this species, expect a moult roughly every 21-42 days for spiderlings, every 60-90 days for juveniles, and every 81-115 days for sub-adults, with adult females moulting around every 4.5 months (up to 5.9 months at the extreme). Males never moult again after their ultimate (mature) moult.
After the moult: fang hardening time
The new exoskeleton stays soft, with fangs that cannot grip, for roughly 4 days in this species. Offer no food and no handling for about 7 days - feeding too early is how fresh moulters get injured. The shed exuvium is also the best sexing tool there is - see our tarantula sexing guide for what to look for.
Genuinely worried about behaviour that is not moulting? Our "Is my T okay?" triage tool walks the danger signs one by one.
What ongoing care does an Orange Tree Spider Tarantula need?
🪞 Moulting
Arboreals often moult suspended in a web hammock. Do not disturb, remove prey, and slightly raise humidity around the time. Wait 5-7 days post-moult before offering food. Adult intervals apply to mature females - males never moult after their ultimate moult.
🧹 Cleaning
Spot clean webbed boluses when visible, refresh the water dish weekly. Full clean only when soiled - established webbing is valuable to the spider.
✋ Handling
Never. Tapinauchenius are widely called the fastest tarantulas on Earth - small, blindingly quick, and gone before you register movement. Catch cup, sealed lid, zero exceptions.
What are the most common mistakes when keeping Orange Tree Spider Tarantulas?
✓ What They Love
- Tall enclosure with vertical cork
- Strong cross-ventilation
- Mist one wall - let it cycle dry
- Clamping/secure lid - arboreals are escape artists
✕ Common Mistakes
- Waterlogged substrate
- Sealed, unventilated tanks
- Heat from below
- Free handling - jumps and falls kill
