Mangrove Snake — Care Sheet & Morphs

Husbandry requirements

Mangrove Snake — origin: Southeast Asia: Indonesia, Malaysia, Borneo, Sumatra, Thailand, Vietnam, the Philippines and Singapore. Inhabits mangrove forests, humid lowland forests and riparian zones..

Terrarium temperature gradient

Night min22 °C

Cool side24–26 °C

Warm side28–30 °C

A nocturnal tropical-forest species: no true heliophilic hot spot required. Create a gentle gradient with a warm point (28-30 °C) via a radiant panel or a thermostat-controlled cable/mat, and a cool zone at 24-26 °C. Nighttime drop to ~22 °C. Avoid any unprotected heat source: risk of burns (the snake coils around hot elements).

Enclosure (adult)

120 × 60 × 120 cm

A tall arboreal terrarium, richly planted, with a large water feature (arboreal semi-aquatic species). Perfectly secured and lockable closure (a powerful, venomous and skilful escape-artist snake).

Minimum for an adult: aim for 150 x 60 x 120 cm or more. Height and numerous sturdy horizontal/diagonal branches are essential. Provide hides up high and on the ground, dense foliage (real or artificial) and sufficient ventilation despite the high humidity.

Humidity

70–90 %

High and constant humidity (mangrove). Regular mistings, moist substrate and a large body of water. Maintain good ventilation to avoid stagnant air and respiratory infections.

Substrate

Coconut fibre (coco humus)Orchid bark / resin-free pine barkFertilizer-free tropical soilSphagnum moss (humid areas and hides)Cypress mulch

A moisture-retaining substrate, but neither waterlogged nor mouldy. A layer of sphagnum in the hides. Remove droppings and soiled areas quickly to limit parasites and bacteria.

UVB

Optional

Not essential as a nocturnal species, but low UVB (T5 ~5-6%, Ferguson index 1-2, filtered by the foliage) is beneficial for well-being and metabolism. Provide densely shaded areas and elevated hides.

Water source

Always available

A large, stable and heavy water bowl, big enough to allow immersion (a semi-aquatic species that likes to bathe and takes refuge in it). Clean water renewed frequently; it also helps maintain humidity.

Origin

Colubridae

Southeast Asia: Indonesia, Malaysia, Borneo, Sumatra, Thailand, Vietnam, the Philippines and Singapore. Inhabits mangrove forests, humid lowland forests and riparian zones.

Feeding & health

Diet

Carnivore — In captivity: appropriately sized rodents (mice, rats); some individuals prefer birds/chicks. In the wild: opportunistic (birds, rodents, lizards, frogs, fish, other snakes).

Many specimens (especially wild-caught) start on birds/chicks and must be gradually transferred to rodents (scent-rubbing, thawed). Feed preferably with tongs, using a hook and great caution given the reactivity and the venom. Juvenile: every 5-7 days; adult: every 10-14 days. Avoid overfeeding (obesity).

Breeding

Oviparous

Clutch 4–15 eggs/young. A clutch of 4 to 15 eggs after a seasonal rest/cooling period. Incubation of about 85-95 days at ~27-29 °C. Breeding is rather reserved for experienced keepers (managing the venom, the aggression and the conditions).

Health watch points

Respiratory infections (air too cold, stagnant or poorly managed humidity)
Internal parasites (nematodes, protozoa) very common in wild-caught animals
Stomatitis (mouth rot) and lesions linked to import stress
Dehydration and food refusal in newly imported wild animals
Thermal burns (coiling around heating elements) and dysecdysis (difficult sheds) if humidity is insufficient

Frequently asked questions

Answers to the most common questions about keeping the mangrove snake.

Is the mangrove snake dangerous to handle?▾

It is a venomous rear-fanged (opisthoglyphous) species with a highly defensive temperament: it rears up, hisses and bites readily. Its venom is moderate but can cause swelling, pain, bruising and local or systemic reactions; prolonged bites are medically significant. Handling should be limited to the strict minimum, with a hook or a restraint box.

Does this species tame down over time?▾

No, it is notoriously reactive and shows no real habituation to handling. This is an advanced-level snake, not recommended for beginners or households with children, best regarded primarily as a display animal.

How large does the mangrove snake grow?▾

It is a large species typically measuring 1.8 to 2.4 m, with some females exceeding 2.5 m. Its body is slender, muscular and highly mobile, which increases the caution required during any intervention in the terrarium.

What terrarium does it need?▾

A tall, richly planted arboreal terrarium with a large water feature, at least 120 x 60 x 120 cm but ideally 150 x 60 x 120 cm or more. Height and numerous sturdy horizontal and diagonal branches are essential, along with hides up high and on the ground and dense foliage. The closure must be perfectly secured and lockable.

Why provide it with a large water bowl?▾

It is a semi-aquatic arboreal species that likes to bathe and take refuge in water. Provide a stable, heavy bowl large enough to allow immersion, with clean water renewed frequently; it also helps maintain humidity.

What temperatures should be maintained?▾

A warm point at 28-30 °C and a cool zone at 24-26 °C, with a nighttime drop to around 22 °C. This nocturnal tropical-forest species does not require a true heliophilic hot spot: create a gentle gradient via a radiant panel or a thermostat-controlled cable/mat.

Is there a burn risk with the heating?▾

Yes, this is a major point of vigilance: the snake readily coils around heating elements. Any unprotected heat source must therefore be avoided to prevent thermal burns.

What humidity level should be targeted?▾

High and constant humidity of 70 to 90%, reflecting the mangrove, achieved through regular misting, a moist substrate and a large body of water. Nonetheless, maintain good ventilation to avoid stagnant air and respiratory infections.

What does it eat and how should it be fed?▾

In captivity, it eats appropriately sized rodents (mice, rats), with some individuals preferring birds or chicks; in the wild, it is opportunistic (birds, rodents, lizards, frogs, fish, other snakes). Many wild-caught specimens start on chicks and must be gradually transitioned to rodents by scent-rubbing. Feed with tongs, using a hook and great caution: juveniles every 5-7 days, adults every 10-14 days.

What substrate works best?▾

Coconut fibre, orchid bark or resin-free pine bark, fertilizer-free tropical soil, sphagnum moss in humid areas and hides, or cypress mulch. The substrate should retain moisture without becoming waterlogged or mouldy; remove droppings and soiled areas promptly to limit parasites and bacteria.

Can it be bred easily?▾

Oviparous, it lays 4 to 15 eggs after a seasonal rest or cooling period, with an incubation of about 85 to 95 days at around 27-29 °C. Breeding remains rather reserved for experienced keepers, owing to the venom, aggression and conditions that must be managed.

What are the main health problems?▾

Respiratory infections (air too cold, stagnant, or poorly managed humidity), internal parasites very common in wild-caught animals, stomatitis and lesions linked to import stress, dehydration and food refusal in newly imported wild specimens, as well as thermal burns and difficult sheds if humidity is insufficient.
