Xenodon pulcher
The Tricolour Hognose (Xenodon pulcher) is found in humid regions of South America — a small species averaging about 2 ft. Dry heat with a probe target of 82 °F, a wet box for humidity choice, Shadedweller UV, and a rodent diet sized to girth. Rear-fanged (bee-sting allergy caution).

01 · Housing
Small dry-setup hognoses (~2 ft). Fill the floor with hides, branches and enrichment, add a wet box, artificial foliage, and a clear temperature gradient. Adult minimum wooden vivarium 24″ × 18″ × 18″, or larger as desired.
Adult minimum size
24″ W × 18″ D × 18″ H
Wooden vivarium minimum, or larger as desired. Dry setup with heat bulb, Shadedweller UV, wet box, and cool-side water bowl.

02 · Climate
Dry heat with a clear cool-to-warm gradient (probe 82 °F · cool ~78 · mid 84–86 · warm 90–95 · bask ~100 °F), Shadedweller UV for nocturnal species, and a wet box so the snake can choose humidity rather than high ambient moisture.
When the heat bulb and thermostat sensor are placed as instructed, a probe target of 82 °F (28 °C) creates this spread. The probe point is not the basking spot.
| Zone | Temperature |
|---|---|
| Cool side | ~78 °F (~26 °C) |
| Probe point (thermostat probe target) | 82 °F (28 °C) |
| Middle | 84–86 °F (29–30 °C) |
| Warm side | 90–95 °F (32–35 °C) |
| Basking spot | ~100 °F (~38 °C) |
| Night drop | Reduce thermostat by ~72 °F (~22 °C) at night · ~10 °F drop |

Always have the thermostat dial turned down before you plug it into the mains for the first time. Set the probe to 82 °F (28 °C) for daytime once the heat bulb and sensor are in place.
03 · Nutrition
Rodent feeders sized to girth. Settle first, then build a steady schedule — evening or overnight feeds suit most individuals.

| Prey | Frequency |

| 2 pinkies | 2× per week |
| 1 fluff | 2× per week |
| 2 fluffs | Every 5 days |
| 1 hop | Every 5 days |

| 1 medium mouse | Every 7–10 days |
| 1 large mouse | Every 10–12 days |
| 1 extra-large mouse | Every 14 days |
Snakes may naturally refuse food at times — breeding season (males especially can go off feed for many months), and during shed (slough). The shed process can take 1–2 weeks; you may not notice the very beginning.
Speak to a member of staff if feeding concerns continue after settlement and shed cycles.
04 · Behaviour
Patience first. Settling and regular feeding come before handling. Note the rear-fang / allergy caution before you commit to this species.
Allow the snake to settle and begin eating regularly before handling — we recommend at least two successful feeds first. Adapting is stressful; early handling can make it worse.
Initial sessions: 5–10 minutes only. Lengthen as the snake becomes more comfortable.
Always wash or disinfect hands before and after handling to prevent bacteria transfer both ways.
Do not use aerosols or plug-in air fresheners near the enclosure — the chemicals can harm reptiles.
05 · Welfare
Prevention starts with correct husbandry — heat, UV, hydration, and safe substrate working together.
Correct temperatures, hydration, and UV where used keep the immune system and gut working well — supporting essential physiological processes.

Questions
They average about 2 ft. Adult minimum is a wooden vivarium 24″ × 18″ × 18″, or larger as desired. Dry pelleted straw (or a coarser sand-style substrate — not very fine sand), fill the floor with hides, branches and enrichment, artificial foliage, a wet box with damp moss, and a cool-side water bowl. Heat bulb with the ¼/¼ probe method and Shadedweller UV.
Set the thermostat probe to 82 °F (28 °C) by day with the heat bulb about one-quarter from one side and the probe one-quarter from the opposite side, hanging down the back a few inches from the floor. That creates a gradient of about 78 °F cool, 84–86 °F middle, 90–95 °F warm, and around 100 °F under the basking bulb. At night reduce the thermostat by about 10 °F to around 72 °F (22 °C).
Although nocturnal, use a Shadedweller UV system designed for nocturnal and crepuscular reptiles (terrestrial or arboreal forms). Research supports that they use daylight UV at some point. Daytime heat about 12 hours in winter and up to 16 hours in summer when days are longer.
They are rear-fanged venomous. Venom is not significant enough to harm most humans, but if you are hypoallergenic or allergic to bee stings we strongly advise against keeping one.
Allow the snake to settle and begin eating regularly before handling — at least two successful feeds first. Early sessions 5–10 minutes only; lengthen as they become more comfortable. Wait about 24 hours after feeding before handling so digestion is not interrupted. Always wash or disinfect hands before and after. No aerosols or plug-in air fresheners near the enclosure.
Young snakes twice a week while growing; sub-adults about every five days; adults about once a week. Prey size should match the snake’s girth (not head size). Move up a size if a meal leaves no noticeable bulge a few hours after eating. Feed in the evening or overnight; remove uneaten food by morning. Do not feed during shed — wait until after the shed is complete.
