Adult enclosure recommendation
Our recommended minimum: 5′ × 2′ × 3′ (152.4 × 61 × 91.5 cm), length × depth × height.
Usable internal space for 1 adult animal. One Australian Antaresia maculosa up to 5′ (152 cm) total length, including documented Cape York A. m. peninsularis. A confirmed adult no longer than 4′ (121.92 cm) can use the separate profile. Papuan A. papuensis is excluded.
Height is the usable internal envelope, including the space reserved for substrate and water. Check the remaining movement space and lamp clearance after installation.
No separately supported preferred triplet is established. Add usable depth and connected climbing routes for an active individual, keeping the stated full-extension floor and environmental choices.
We retain the species specialist's 5′ × 2′ (152.4 × 60.96 cm) larger-adult floor and add 1′ (30.48 cm) to its 2′ (60.96 cm) height for connected branches above a ≈ 3.937″ (10 cm) planted substrate layer. This is an explicit editorial welfare adaptation, not an experimentally validated minimum.
Keep enclosure length at least equal to actual tail-inclusive total length, and depth at least 40% of that length under the general snake welfare framework. Retain the profile's 3′ (91.44 cm) internal height for furnishing. A 5′ (152.4 cm) adult uses 5′ × 2′ × 3′ (152.4 × 60.96 × 91.44 cm); a confirmed 4′ (121.92 cm) adult uses 4′ × 2′ × 3′ (121.92 × 60.96 × 91.44 cm). Larger individuals need the rule recalculated and additional height where climbing routes are restricted.
Confirmed mature adult no longer than 4′ (121.92 cm) total length
Our recommended minimum: 4′ × 2′ × 3′ (122 × 61 × 91.5 cm), length × depth × height. Full horizontal extension with the same depth and added climbing height; juvenile size alone does not qualify.
- Floor space
- Keep the entire length available for straightening and travel beside warm and cool hides, water and vegetation.
- Climbing space
- Install connected sturdy branches and elevated retreats with secure attachments and access for inspection. A tall empty enclosure supplies no climbing route.
- Substrate
- Reserve about ≈ 3.937″ (10 cm) soil in a planted setup, leaving ≈ 31.89″ (81 cm) above it within the 3′ (91.44 cm) internal envelope before fixtures. This is a plant and furnishing allowance, not a demonstrated biological digging minimum. Cleanable alternative bedding is acceptable with functional retreats.
- Water
- Provide a stable vessel large enough for voluntary full-body soaking, with continuous clean drinking water and an easy exit. Remove fouled water immediately.
- Security and ventilation
- Lock doors, close small gaps, secure heavy furnishings to the base, guard thermostatic heat and maintain ventilation through foliage.
Meeting these dimensions alone does not establish suitability. Check the usable layout, environmental conditions, equipment clearance and the individual animal’s requirements before occupation.
Keep the Australian identification with the animal
Confirm Antaresia maculosa and retain breeder and locality documents. The Cape York form, A. m. peninsularis, belongs within this guide; Papuan animals now identified as A. papuensis need a separate plan. Do not choose a smaller enclosure from an unverified locality name. Measure the individual, ask about mature parents and house one snake so meals and body condition can be tracked accurately.
Our recommended adult enclosure
For one adult up to 5′ (152 cm) total length, we recommend at least 5′ × 2′ × 3′ (152 × 61 × 91 cm), usable internal length × depth × height. A confirmed mature individual no longer than 4′ (122 cm) can use 4′ × 2′ × 3′ (122 × 61 × 91 cm). Total length includes the tail. Height includes substrate. We retain the specialist's larger-adult 5′ × 2′ (152.4 × 60.96 cm) floor and increase height by 1′ (30.48 cm) for functional branches above the ground layer. This is our editorial welfare minimum, not a scientifically validated cutoff.
Keep length at least equal to the actual snake's length and depth at least 40% of that length; retain the stated climbing allowance. Larger animals need those dimensions recalculated. No separate preferred triplet is established. Extra depth and connected routes are worthwhile for an active snake, including some males, but sex alone does not determine housing. Juvenile setups are temporary; plan the next size before movement is restricted.
Furnish the floor and the climbing routes
Provide snug ground hides at different temperatures and stable elevated retreats connected by branches. Preserve the full-length floor route after adding water, plants and supports. In a planted setup, reserve about ≈ 3.937″ (10 cm) of soil, leaving about ≈ 31.89″ (81 cm) above it within the 3′ (91.44 cm) envelope before lamps and guards. That depth supports the chosen planting and layout; it is not a required biological digging depth for every spotted python. Removable cleanable bedding is also acceptable. Secure heavy objects independently of soil and make every retreat accessible for inspection. Meeting dimensions alone does not establish suitability.
Measure separate warm, cool and night conditions
Start with a basking surface and warm hide near 90 °F (32 °C), and cool-side air about 78–84 °F (26–29 °C), using the species specialist's clearly labeled measurement locations. Read the surface with an infrared thermometer and place independent air probes inside the warm retreat and shaded cool area. Guard and thermostat heat. For ordinary nights we recommend about 70–75 °F (21–24 °C): this retains the newer veterinary 69.8 °F (21 °C) floor within the species article's night range. It is an editorial operating choice, not a demonstrated safe limit. Youngsters need dependable access to warmth and cover; never allow the whole enclosure to sit at the surface temperature.
Where recommendations differ
Older genus veterinary guidance uses 91.4–100.4 °F (33–38 °C) at the basking area and 60.8–68 °F (16–20 °C) at the cool end, while the species article uses the narrower gradient above. The breeder's 85–90 °F (29–32 °C) hot zone is not precisely separated into air and surface readings. We choose the explicit species measurement protocol with the newer night floor. The wider veterinary protocol remains an experienced-care alternative when its full context and individual outcomes are documented; combining its hottest and coldest values with another plan is not evidence of a better gradient.
The same species article permits 20–80% humidity, whereas the breeder uses 50–70%. We recommend the narrower 50–70% reference at the cool side, with a humid retreat, dry resting surfaces and ventilation. A broad tolerance claim is not a reason to force large daily swings. Check moisture beneath the bowl and shedding quality as well as the meter. The sources give husbandry experience rather than comparative trials.
Provide a light cycle and a usable UVB (ultraviolet B) gradient
Use about 12 hours of daylight and darkness overnight. We recommend voluntary daytime UVB access with the species specialist's UVI (ultraviolet index) 2–3 local exposure as a starting reference and near-zero exposure inside cover. This is practical guidance, not an experimentally established dose requirement. Measure at reachable back height after fitting branches and mesh; a bulb percentage cannot set exposure. The breeder maintains snakes without UVB, while current veterinary guidance supports providing it. That history does not prove UVB has no value, and it does not justify forcing the animal to remain exposed in order to stay warm.
Choose a feeding interval that fits the animal
Offer appropriately sized, fully thawed whole prey. Begin established youngsters around every 7–10 days and mature animals around every 14–21 days, then adjust portion size and interval to growth, weight and body condition. This adult starting choice fits the veterinary 2–3 week reference and the species article's broader interval. The breeder reports adult meals every 5–7 days; smaller meals and different growth or activity can change requirements, but that faster schedule is not our default for an inactive mature snake.
Use a balanced whole-rodent diet without routine supplement dusting unless a dietary or veterinary reason is identified. Some care sheets advise powders automatically; general veterinary nutrition guidance does not consider them necessary with suitable whole rodents. Diet composition matters. Keep accepted meals and refusals in the same record, and investigate sustained loss of condition instead of repeatedly offering larger prey.
Keep water, cover and daily care accessible
Provide continuous fresh water in a stable bowl large enough for voluntary soaking, and replace it immediately after contamination. Inspect water, closures, temperature readings and visible condition daily, removing waste promptly even in a bioactive enclosure. Check that growing plants do not block retreat access or change lamp distances. Introduce new animals through separately planned arrival care, with veterinary support as needed.
Keep handling brief, support the body and allow quiet digestion. Record sheds and comparable weights. Repeated regurgitation, abnormal breathing, wounds, persistent shedding problems or declining condition need a reptile veterinarian. A report of seasonal fasting does not prove that a sick snake is simply brumating; routine cooling solely for a claimed health benefit is not established here. Prepare a backup-carer sheet with the current measured routine and the route for changing water without an escape.
