Adult enclosure recommendation
Our recommended minimum: 6′ × 3′ × 2′ (182.9 × 91.5 × 61 cm), length × depth × height.
Usable internal space for 1 adult animal. One adult Python brongersmai up to 6′ (183 cm) total length. Females commonly exceed males in length; measure the actual animal and retain space for further growth.
Height is the usable internal envelope, including the space reserved for substrate and water. Check the remaining movement space and lamp clearance after installation.
A wider/longer enclosure provides more movement and bathing choices, but no separate tested or clearly supported preferred numerical threshold was found. First preserve the full-length floor and large basin.
Our 6′ × 3′ × 2′ (182.88 × 91.44 × 60.96 cm) recommendation adopts the largest adult layout in Mortal Coil’s keeper guidance and provides full extension for a six-foot adult. The source gives reversed, unlabeled axes; the length × depth × height orientation is our terrestrial design interpretation, not a validated welfare threshold.
Keep usable floor length at least the actual total length. For a 7′ (213 cm) individual, extend the example to at least 7′ × 3′ × 2′ (213 × 91 × 61 cm) and enlarge depth or height if its body, basin, retreats or equipment cannot fit without narrowing movement. This extension of the six-foot layout is our editorial application of full-body extension, not a validated universal scaling formula.
A measured 7′ (213 cm) adult
Our recommended minimum: 7′ × 3′ × 2′ (213.4 × 91.5 × 61 cm), length × depth × height. Extend the six-foot layout to allow full body length. Increase other axes if turning, water, cover or safe fixture clearance requires more space; this is our conditional editorial example.
- Floor space
- 18 sq ft (1.67 m²) gross floor in the six-foot example. Keep a full-length extension route and broad turning room after installing hides and water.
- Climbing space
- Provide low, broad, firmly anchored supports. The 2′ (61 cm) internal height includes bedding and equipment clearance; do not fill it with high unsupported branches.
- Substrate
- Use clean absorbent paper with a separate moist refuge, or maintained cypress and sphagnum. Loose refuge material must permit concealment; no universal numerical depth is established.
- Water
- Provide a stable basin for full-body immersion and an easy exit. Size it to the coiled animal’s actual girth, without consuming the long movement route.
- Security and ventilation
- Provide visual cover, ventilation, strong locks and secure temporary containment for heavy maintenance. Guard and thermostat all heat sources.
Evidence gaps requiring review:
- A measured species-specific UVB (ultraviolet B) exposure target is not established by the opened P. brongersmai sources. The lighting plan needs documented assessment; a related species’ UVI (ultraviolet index) is not a substitute.
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 species name with the animal
Keep the name Python brongersmai with the animal’s records. This red blood python needs substantial floor space and broad support despite its relatively short tail. Females commonly reach 4′–6′ (122–183 cm), males 3′–5′ (91–152 cm); unusually larger animals occur. Do not apply this sheet automatically to Borneo or Sumatran short-tailed pythons.
Choose a documented captive-bred feeder and obtain its actual meal, weight and health history. Expect individual defensive responses and use calm, predictable care. An animal that often rests beneath cover still needs opportunities to move and choose conditions.

Floor space and support matter
We recommend at least 6′ × 3′ × 2′ (183 × 91 × 61 cm, length × depth × height) of usable internal space for one adult up to 6′ (183 cm) total length. This supplies 18 sq ft (1.7 m²) of gross floor. Females commonly grow longer than males; enlarge length for an individual exceeding 6′ (182.88 cm). There is no defensible single maximum adult size that makes growth checks unnecessary.
This is our welfare recommendation, based on specialist large-adult layouts and full extension. NERD (New England Reptile Distributors) gives a 4′ (121.92 cm) cage-length minimum, but that is shorter than many adult females it describes. We choose the larger footprint and do not treat a short tail or a quiet resting posture as evidence that little space is needed. No separately established numerical preferred size was found; extra floor is useful only if it remains accessible after furnishings.
Provide broad secure cover, warm and cooler retreats, low stable climbing surfaces and a basin large enough for the coiled animal to soak fully. Use absorbent bedding with clean dry resting surfaces; deep standing wet substrate is unnecessary. The 2′ (60.96 cm) height includes bedding and fixture clearance. Strong supports, ventilation, thermal choice and safe servicing are necessary alongside the dimensions.
Keep warmth local
Provide a warm contact surface around 86°F (30°C), with cooler shelter air around 76–78°F (24–26°C, rounded). This is our implementation of Mortal Coil’s modest basking protocol, which places a thermostat probe at the heated contact spot. Check the surface with a contact probe and infrared thermometer, and measure air separately at snake level in both retreats.
Keep the same moderate gradient overnight with visible lamps off; a deliberate night drop is not required in the selected keeper protocol. Any overnight heating must be lightless and thermostatically controlled. The ReptiFiles temperament article describes 78–82°F (25.5–28°C) ambient air across several short-tailed taxa. It does not justify heating every retreat to the contact-surface target.
Moisture without a soaked floor
Aim for 60–70% relative humidity, measured by a shielded sensor beside the resting area and recorded with local air temperature. Provide a clean moist refuge as a choice, while keeping the main resting surface dry. Inspect beneath the animal and its cover, where wet waste can persist after the visible floor has dried.
Use cypress and sphagnum in a maintained refuge, or paper for observation with a separate moist hide. Provide enough loose material in that refuge for the snake to conceal itself; the sources do not establish one numerical substrate depth for every adult. Inspect for material collecting around the mouth and seek veterinary help for irritation rather than extracting embedded debris yourself.
Keep a stable, nonporous basin large enough for comfortable full-body immersion and an easy exit. Check it daily, replace soiled water immediately and clean the vessel before refilling. Do not force routine baths or treat bowel problems with oils or enemas.
Feed for condition, not bulk
Offer thawed whole rodents close to the snake’s widest girth, adjusting meal size and interval to growth and body condition. Our starting schedule is weekly through the first year, roughly every two weeks in the second year, then every three to four weeks for a mature adult. These are keeper-derived starting intervals, not a growth target.
We do not routinely dust complete whole prey with supplements; assess an identified dietary or medical need with a reptile veterinarian. Log meals and comparable weights. Allow quiet digestion and support the entire body during necessary transfers. A long stool interval alone is not a diagnosis, but persistent appetite change, regurgitation, swelling or straining requires veterinary assessment.
Budget for the adult
Budget for at least two decades, with 25 years or more possible in the breeder account. Durable adult housing, large water changes, prey storage and suitable transport remain ongoing commitments. Keep a competent substitute caretaker familiar with the animal and its service routine.

Rehearse the heavy jobs before arrival
Make a service checklist for the full water vessel, the largest hide and the adult transfer container. Identify where each item is placed while being cleaned and whether it can pass through the door without catching the lock. A blood python's broad body and substantial equipment make these practical questions especially important.
During an empty-enclosure rehearsal, complete a water change and reach the rear corners without moving unsupported decorations. Put the required tools within reach of the service area. Keep the temporary holding arrangement ready and obtain species-experienced help with necessary transfers. If every ordinary job requires extensive restraint, revise the enclosure access before the animal arrives.
Provide daylight and assess UVB separately
Offer a regular day and dark-night cycle with deep shaded retreats. We use 12 hours of visible daylight as an ordinary maintenance routine, an editorial choice rather than a measured species optimum. Keep lamps and hot fittings inaccessible.
Low-level UVB may be beneficial, but the opened Python brongersmai accounts do not establish a measured species-specific exposure target. Record the fixture, mesh, closest reachable position and actual UVI with a suitable meter; obtain a documented exposure plan before commissioning UVB. Do not import the Borneo short-tailed python’s numerical zone merely because the animals are related.
Where recommendations differ
The NERD sheet gives a four-foot cage minimum, while Mortal Coil lists adult layouts reaching 6′ × 3′ × 2′ (182.88 × 91.44 × 60.96 cm) with unlabeled axes. We choose the larger terrestrial orientation, full body extension and adequate space around the soaking basin. These are practical husbandry recommendations, not experimentally validated cage thresholds.
Feeding intervals also vary: the ReptiFiles mixed-taxon account uses 10–14 days for yearlings, while Mortal Coil offers weekly prey through the first year. Begin with the established animal’s successful routine, then use our age-based schedule with condition checks. Slow growth or excess weight is a reason to reassess prey quantity and health, not to follow a calendar mechanically.
Prepare arrival and recognize illness
Prepare separate housing and dedicated tools when other reptiles are present. Arrange an initial reptile-veterinary examination within two weeks and agree screening and release criteria; a quiet animal or one normal meal does not establish health.
Seek prompt advice for breathing difficulty, mouth discharge, repeated regurgitation, skin lesions, marked weakness or sustained weight loss. Bring feeding and environmental records. Remove waste daily, clean equipment with an appropriate product under its label directions and keep a secure holding arrangement available during major maintenance.
