Tricolor Hognose Caresheet


Background Information
The Tricolor Hognose is a small colubrid species from Argentina and Bolivia, South America. As their name suggests they have 3 colurations on their body - red, white and black.The temperament of tricolours can vary between individuals, some can be slightly more shy and secretive than others but generally they are a placid and inquisitive species. They come out at night to hunt and during the day they stay buried underground to avoid predators and the heat of the day. Fully grown adults are from 2 - 2.5 ft in length and are not sexually diamorphic.

Captive Requirements and Welfare
Due to its tropical origin, the best suited home for your tricolor would be a glass vivarium as this is better at maintaining humidity than wooden vivariums and temperature control is much easier. However, a wooden vivarium would suffice. A rainforest environment should be replicated to make it as natural as possible for your tricolor – using eco earth will give it the opportunity to burrow and spraying the enclosure occasionally would also help to raise the humidity slightly. Unlike other hognose species, tricolors have a much slender sized body and smaller head therefore it is important that this is noted when choosing what size food to feed.

Vivarium size

30x30x30cm for hatchling
2ft x 1.5ft x 1.5ft for adult

Daytime Temperature (cool – warm)

24 – 32 ‘C

Night-time Temperature

18 – 22 ‘C


65% spray substrate lightly to dampen or provide a moist hide however have been kept in drier conditions with no problems

Heating / Lighting Equipment (on timer)

Spot bulb during day, room temperature at night

Lighting - T8 2% Natural sun Arcadia UV tube


Most Natural: Eco Earth
Alternatives: Repti - Bark, aspen, woodchip


2 at minimum although due to their burrowing nature deep substrate could count as your 2nd hide


Branches and fake plants aid shedding


Fresh water topped up when needed, clean out water bowl every few days to prevent slime build up

Food (Feeding)

Pinkies for hatchlings then increase the size as they grow. Always take the snake out and feed in a separate box to prevent substrate being eaten. Be careful not to rush in changing sizes, giving them sizes too big could put them off eating.


Spot pick weekly, full clean monthly
