African Helmeted Turtle — Care Sheet & Morphs

Q: How big does an adult African Helmeted Turtle get?

An adult African Helmeted Turtle typically measures 15–25 cm.

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.

How big does an adult African Helmeted Turtle get?▾

An adult African Helmeted Turtle typically measures 15–25 cm (shell length: generally 15-20 cm, with large males rarely reaching ~30 cm. in this species, females are often smaller than large males.).

What temperature and humidity does a African Helmeted Turtle need?▾

A gradient of roughly 20–23 °C on the cool side to 24–27 °C on the warm side, with a basking spot of 30–35 °C. Humidity 50–80 %.

What does a African Helmeted Turtle eat?▾

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

Is the African Helmeted Turtle a good reptile for beginners?▾

Beginner + level. Curious and active, but often aggressive towards conspecifics (fights, bites). Being a pleurodire, it cannot retract its head into the shell: it defends itself by biting hard (powerful jaws) and releasing a musky secretion. Handle as little as possible; like all turtles, a potential carrier of Salmonella (zoonosis): rigorous hand hygiene. Plan ahead: a lifespan of 25–50 yrs.
