Black-tailed cribo — Care Sheet & Morphs

Husbandry requirements

Black-tailed cribo — origin: From Mexico (Atlantic slope) across Central America to northern Colombia and Venezuela. Occupies varied habitats: humid and dry tropical forests, forest edges, savannas and open areas, often near water..

Terrarium temperature gradient

Night min21 °C

Cool side24–27 °C

Warm side28–31 °C

Basking spot32–35 °C

Diurnal, heliophilic species: provide a true basking spot under a lamp (guarded to prevent burns) and a marked thermal gradient. A moderate nighttime drop is tolerated; do not stay below 21 °C for extended periods.

Enclosure (adult)

240 × 120 × 90 cm

Spacious, sturdy and fully secured terrestrial terrarium

A very active, powerful and large snake: provide the largest possible space (ideally at least the length of the snake). Lockable lid and solid structure — a formidable escape artist. Provide sturdy hides, a few low branches and a large ground-level exercise area.

Humidity

60–80 %

A humid tropical atmosphere but well ventilated: avoid stagnant air. Maintain a more humid zone around the water source and a drier side. Light misting as needed.

Substrate

Coco fibreTopsoil free of fertilizer and pesticideOrchid bark or cypress mulchFree-draining bioactive substrate

Absorbent substrate, to be cleaned and renewed very often: droppings are liquid, abundant and foul-smelling (high metabolism). Avoid a constantly waterlogged substrate, a source of bacterial dermatitis.

UVB

Recommended

Recommended. An active diurnal species: UVB lighting (Ferguson zone 2–3, UVI ~2–3, T5 tube 5–7%) supports metabolism, vitamin D3 synthesis and vitality. Combine with bright ambient lighting on a regular photoperiod.

Water source

Always available

A large water container allowing full immersion of the body: the animal bathes and defecates in it frequently. Clean and renew very regularly (abundant liquid waste) to keep the water clean at all times.

Origin

Colubridae

From Mexico (Atlantic slope) across Central America to northern Colombia and Venezuela. Occupies varied habitats: humid and dry tropical forests, forest edges, savannas and open areas, often near water.

Feeding & health

Diet

Carnivore — apex predator, ophiophagous — Rodents, birds and chicks, fish, amphibians and other snakes (including venomous ones in the wild).

Very high metabolism: frequent feedings required. In captivity, a rodent-based diet (rats/mice) possibly supplemented with fish or chicks. Ophiophagous and opportunistic: house STRICTLY alone (risk of cannibalism). Non-venomous. Many individuals in the trade are wild-caught (WC), often heavily parasitized and stressed — favour captive-bred (CB) specimens. The species is generally not listed under CITES (not to be confused with D. couperi, protected in the United States), but check local regulations before acquiring one.

Breeding

Oviparous

Clutch 4–15 eggs/young. Breeding is often stimulated by a cooling/light brumation period (~15–20 °C for a few weeks). Eggs are incubated at around 27–29 °C for approximately 75–90 days.

Health watch points

Respiratory infections (temperature too low or insufficient ventilation)
Internal and external parasites, very common in wild-caught individuals
Stomatitis (mouth rot)
Bacterial dermatitis / scale rot linked to soiled or overly damp substrate
Obesity and hepatic lipidosis from overfeeding

Frequently asked questions

Answers to the most common questions about keeping the black-tailed cribo.

How does the black-tailed cribo behave — is it easy to handle?▾

It is a lively, intelligent and very active snake. It can be defensive in its enclosure (loud hissing, tail vibration, bites) but generally handles calmly once taken out. It is not venomous, but its bite remains powerful given its size.

How big can it get as an adult?▾

It measures 180 to 240 cm as an adult and is very robust and muscular; some exceptional specimens exceed 2.6 m. Both females and males reach large sizes.

What size terrarium should be provided for an adult?▾

Allow at least 240 x 120 x 90 cm, ideally at least the length of the snake itself. The lid must be lockable and the structure solid, as it is a formidable escape artist; add sturdy hides, a few low branches and a large ground-level exercise area.

What temperature gradient does it need?▾

Provide a cool side at 24-27 °C, a warm side at 28-31 °C and a hot spot under a guarded lamp at 32-35 °C. A moderate nighttime drop is tolerated, but it should not stay below 21 °C for extended periods: this is a diurnal, heliophilic species that needs a marked gradient.

What humidity and substrate suit it?▾

It needs a humid tropical atmosphere of 60 to 80%, but well ventilated to avoid stagnant air, with a more humid zone around the water point and a drier side. An absorbent substrate (coco fiber, fertilizer-free topsoil, orchid bark or cypress mulch, free-draining bioactive substrate) must be cleaned very often, as its droppings are liquid, abundant and foul-smelling.

What does the cribo eat and how often should it be fed?▾

It is an apex ophiophagous predator: rodents, birds, chicks, fish, amphibians and even other snakes (including venomous ones in the wild) make up its diet. Its very high metabolism requires frequent feedings; in captivity, a rodent-based diet supplemented with fish or chicks works well, but each individual must be housed strictly alone due to the risk of cannibalism.

Is it better to acquire a captive-bred specimen rather than a wild-caught one?▾

Yes, clearly: many individuals in the trade are wild-caught (WC), often heavily parasitized and stressed, whereas captive-bred (CB) specimens acclimatize far better. The species is generally not listed under CITES, unlike D. couperi which is protected in the United States, but local regulations should still be checked before any acquisition.

What kind of water point does it need?▾

A large tub allowing full immersion of the body, as it likes to bathe in it and defecates there frequently. The water must be cleaned and renewed very regularly to stay clean at all times.

Does it need UVB lighting?▾

Yes, this is recommended for this diurnal, active species: UVB from Ferguson zone 2-3 (UVI around 2-3, T5 tube 5-7%) combined with ambient lighting and a regular photoperiod supports its metabolism and vitality.

How does the black-tailed cribo reproduce?▾

It is oviparous and lays 4 to 15 eggs, breeding often being stimulated by a cooling or light brumation period around 15-20 °C for a few weeks. Incubation then lasts about 75 to 90 days around 27-29 °C.

What is its lifespan and which health issues should be watched?▾

It typically lives 20 to 25 years with appropriate care, sometimes longer. Stay alert for respiratory infections (too low a temperature or insufficient ventilation), parasites, very common in wild-caught specimens, stomatitis, bacterial dermatitis linked to soiled substrate, and obesity from overfeeding.
