African Helmeted Turtle — Care Sheet & Morphs

Husbandry requirements

African Helmeted Turtle — origin: Sub-Saharan Africa (very wide distribution), Madagascar and the southern Arabian Peninsula; occupies ponds, temporary marshes and slow or stagnant waterbodies. The genus Pelomedusa forms a recently split species complex, so animals in the trade may belong to several closely related forms..

Terrarium temperature gradient

Night min18 °C

Cool side20–23 °C

Warm side24–27 °C

Basking spot30–35 °C

Ideal water temperature 22-26 °C, with a slight gradient allowing thermoregulation. A dry hot spot (heat lamp) of 30-35 °C above the basking platform. At night, the water can drop to 18-20 °C without harm. Avoid any overheating of the water.

Enclosure (adult)

100 × 45 × 45 cm

Aquatic aquaterrarium with a basking platform (a bottom-walking species)

Minimum dimensions for an adult; allow about +50 % of floor area per additional turtle. A secure lid (a good escaper), powerful filtration, easy exit to the dry zone. A poor swimmer: favour shallow to moderate water where the animal reaches the surface effortlessly.

Humidity

50–80 %

An aquatic species: ambient humidity is secondary; it is water quality and temperature that come first.

Substrate

Bare bottom (recommended for hygiene)Fine sandLarge rounded pebbles too big to be swallowed

Absolutely avoid fine gravel and small pebbles (risk of ingestion and digestive blockage). A bare bottom makes cleaning easier and helps maintain good water quality.

UVB

Recommended

Recommended. A UVB tube ~5 % (5.0, or T5 12 % for large volumes / long distances) above the basking area, replaced every 6-12 months. Promotes vitamin D3 synthesis, calcium metabolism and shell health; to be paired with a heat lamp for the dry hot spot.

Water source

Always available

The heart of husbandry. Clean, filtered (powerful filtration) and dechlorinated water; regular partial water changes and quality monitoring (ammonia/nitrites/nitrates). A bottom-walking species and a poor swimmer: keep a shallow to moderate depth with exits and areas where it easily reaches the surface. A secure lid. As most specimens in the trade are wild-caught, quarantine, a veterinary check-up and deworming are strongly advised on acquisition.

Origin

Pelomedusidae

Sub-Saharan Africa (very wide distribution), Madagascar and the southern Arabian Peninsula; occupies ponds, temporary marshes and slow or stagnant waterbodies. The genus Pelomedusa forms a recently split species complex, so animals in the trade may belong to several closely related forms.

Feeding & health

Diet

Carnivore — Earthworms, snails, aquatic insects and larvae, fish, crustaceans, carrion, amphibians

A voracious and opportunistic feeder that hunts from ambush. Offer a varied diet: earthworms, snails, insects, pieces of lean fish, crustaceans and quality pellets for aquatic turtles. Supplement with calcium (cuttlebone). Avoid overfeeding (obesity) and an exclusive diet of fish rich in thiaminase. Highly carnivorous juveniles fed daily; adults 2-3 times a week.

Breeding

Oviparous

Clutch 10–30 eggs/young. A prolific species that can produce several clutches per year. Eggs buried in a loose, damp terrestrial area: provide a laying box (sand/potting soil). Incubation of about 45-75 days at around 28-30 °C. Sex determination appears to be genetic (no marked TSD in the Pelomedusidae). Without a suitable laying site, females risk egg retention (dystocia).

Health watch points

Hypovitaminosis A (eyelid oedema, ocular discharge, abscesses) linked to an unbalanced diet
Aural (tympanic) abscesses, common in aquatic turtles and favoured by poor water quality
Shell and skin rot (bacterial/fungal infections due to dirty water)
Metabolic bone disease (calcium/UVB deficiency, soft or deformed shell)
Internal parasitism and respiratory infections, especially in wild-caught specimens

Frequently asked questions

Answers to the most common questions about keeping the african helmeted turtle.

Does the African helmeted turtle bite or is it dangerous to handle?▾

It is not venomous, but it should only be handled at the strict minimum: belonging to the Pleurodira, it cannot retract its head into the shell and defends itself by biting hard with powerful jaws, or by releasing a musky secretion. Like all turtles, it can carry Salmonella: scrupulous hand hygiene is essential after any contact.

How big does it get?▾

The shell length is generally between 15 and 20 cm, with large males rarely reaching 30 cm. In this species, females are often smaller than large males, unlike many other aquatic turtles.

What aquaterrarium should you provide?▾

A minimum of 100 x 45 x 45 cm suits an adult, with about 50% more floor area per additional turtle. You need an easily accessible basking platform, a secured lid since it is a good escape artist, and powerful filtration; as the species is a poor swimmer, shallow to moderate water where it can reach the surface effortlessly is preferable.

What water quality must be maintained?▾

This is the heart of its care: clean, filtered and dechlorinated water, with regular partial changes and monitoring of ammonia, nitrites and nitrates. Poor water quality directly promotes aural abscesses and shell rot, two common problems in this species.

What temperatures for the water and basking?▾

The water should stay around 22-26 °C with a slight gradient, while a dry hot spot of 30-35 °C above the platform allows thermoregulation. At night, the water can drop to 18-20 °C without any problem, but overheating of the water must be avoided at all costs.

Is UVB recommended?▾

Yes, a UVB tube of about 5% (or T5 12% for large volumes) above the basking area is recommended, to be replaced every 6 to 12 months. Combined with a heat lamp for the dry hot spot, it promotes vitamin D3 synthesis, calcium metabolism and shell health.

What substrate should you use in the tank?▾

A bare bottom is often recommended for hygiene, or failing that fine sand or large pebbles too bulky to be swallowed. Fine gravel and small pebbles must be avoided absolutely, as they expose the animal to a risk of ingestion and digestive impaction.

What does the helmeted turtle eat and how often?▾

It is a voracious, opportunistic carnivore that hunts from ambush like a small crocodile: earthworms, snails, insects, fish, crustaceans and even carrion. Offer a varied diet, supplemented with calcium via a cuttlebone; juveniles are fed daily, adults 2 to 3 times a week, avoiding overfeeding and an exclusive fish diet.

Can several helmeted turtles be housed together?▾

With caution: it is a curious, active species but often aggressive toward its own kind, with possible fights and bites. Each additional turtle requires about 50% more floor area to limit tensions.

What is its lifespan and is it a long-term commitment?▾

Its potential lifespan is high, from 30 to 50 years, even though in captivity many animals live rather 15 to 30 years for lack of optimal conditions and water quality. It is a very long-term commitment to anticipate carefully before acquisition.

How does breeding work?▾

It is an oviparous and prolific species, able to produce several clutches of 10 to 30 eggs per year, buried in a loose, damp terrestrial area. Incubation lasts about 45 to 75 days at around 28-30 °C; without a suitable nesting box, females risk egg retention.

Which health problems should you watch for?▾

Hypovitaminosis A (swollen eyelids, abscesses) linked to an unbalanced diet, aural abscesses and shell rot promoted by poor water quality, metabolic bone disease in case of calcium or UVB deficiency, as well as the internal parasitism common in wild-caught animals, which predominate in the trade.
