African Clawed Frog (Xenopus laevis) Care Sheet
The African Clawed Frog is a fully aquatic amphibian native to southern Africa. Xenopus laevis is unusual among commonly maintained frogs because adults spend their entire lives in water and require an aquarium rather than a terrestrial or semi-aquatic vivarium.
Robust, long-lived and highly food-motivated, African Clawed Frogs can make fascinating captive animals. However, their adaptability has also allowed them to establish invasive populations outside their natural range, making secure containment and responsible disposal of water and biological material particularly important.

NATURAL HISTORY
Xenopus laevis naturally inhabits freshwater environments across southern Africa.
Habitats include:
- Ponds
- Lakes
- Pools
- Slow-moving waterways
- Seasonal wetlands
- Artificial water bodies
African Clawed Frogs are exceptionally well adapted to aquatic life.
They possess:
- Flattened streamlined bodies
- Powerful webbed hind feet
- Small claw-like structures on the hind feet
- Eyes positioned towards the top of the head
- A highly developed lateral-line system
Unlike most frogs, they lack a protrusible tongue.
Food is instead captured and manipulated towards the mouth using the forelimbs.
FULLY AQUATIC LIFESTYLE
African Clawed Frogs remain aquatic throughout adulthood.
They do not require a terrestrial area.
They regularly swim to the surface to breathe atmospheric air before returning underwater.
The enclosure must therefore provide unobstructed access to the water surface.
Although powerful swimmers, they should not be forced to struggle continuously against strong currents.
AQUARIUM
For one or two adults, an aquarium around:
75 × 30 × 30 cm (30 × 12 × 12 in)
provides a useful minimum starting point.
Larger accommodation is strongly encouraged.
Water volume and usable floor area are particularly important.
The aquarium should provide:
- Substantial swimming space
- Open surface access
- Sheltered areas
- Gentle filtration
- Stable water quality
- Secure containment
WATER DEPTH
A water depth around:
20–30 cm (8–12 in)
works well for many adult animals.
Deeper water can also be used provided frogs can easily reach the surface.
The most important consideration is that animals can:
- Surface effortlessly
- Rest without constantly swimming
- Move normally throughout the aquarium
Provide resting structures at different heights where appropriate.
SECURE LID
A secure lid is essential.
African Clawed Frogs can escape through surprisingly small openings and may attempt to leave the aquarium during:
- Maintenance
- Environmental disturbance
- Changes in water conditions
Cable and filter openings should be checked carefully.
An escaped aquatic frog can rapidly become dehydrated.
Secure containment is also particularly important because this species has become invasive outside its natural distribution.
SUBSTRATE
Suitable options include:
- Bare-bottom aquariums
- Fine sand
- Large smooth stones too large to swallow
Avoid small gravel.
African Clawed Frogs feed enthusiastically and may accidentally swallow substrate while taking food.
Gravel of an ingestible size can create a serious gastrointestinal obstruction risk.
Fine sand or a bare-bottom setup makes feeding and cleaning considerably easier.
FURNISHINGS
Provide sheltered areas without excessively reducing swimming space.
Suitable furnishings include:
- Smooth rocks
- Large pieces of aquarium-safe wood
- Robust aquatic plants
- Artificial plants
- Smooth hides
- PVC-type shelters designed safely for aquarium use
All furnishings should have smooth surfaces.
Avoid sharp decorations that could damage the frog’s delicate skin.
Any heavy objects must be positioned securely.
WATER QUALITY
Excellent water quality is fundamental to successful husbandry.
Amphibians possess highly permeable skin and can be particularly sensitive to waterborne contaminants.
Water should be:
- Appropriately treated
- Free from harmful ammonia
- Free from harmful nitrite
- Maintained at low nitrate concentrations
- Free from chlorine and problematic chloramine
- Regularly monitored
A properly cycled aquarium is strongly recommended.
THE NITROGEN CYCLE
An established biological filter contains microorganisms that process toxic nitrogenous waste.
Waste initially produces:
Ammonia
which is converted into:
Nitrite
and subsequently:
Nitrate
Both ammonia and nitrite should remain at:
0 ppm
in an established aquarium.
Nitrate is less immediately toxic but should be controlled through appropriate water changes and maintenance.
The aquarium should ideally be fully cycled before frogs are introduced.
FILTRATION
Biological filtration is strongly recommended.
Suitable filtration can include:
- Sponge filters
- Internal filters
- External filters with appropriately protected intakes
African Clawed Frogs produce substantial amounts of waste.
The filter should therefore provide adequate biological capacity.
However, water movement should remain moderate.
Extremely powerful currents can cause unnecessary stress.
Filter intakes should be protected so frogs cannot become trapped or injured.
WATER CHANGES
Regular partial water changes are necessary even with effective filtration.
A useful starting point is approximately:
20–30% weekly
although the actual requirement depends upon:
- Aquarium size
- Number of frogs
- Feeding
- Filtration
- Water testing
- Waste production
Water testing should determine the maintenance schedule rather than relying solely on a fixed percentage.
Replacement water should be appropriately treated and reasonably temperature matched.
WATER TEMPERATURE
African Clawed Frogs generally prefer relatively cool water.
A useful routine range is approximately:
18–24°C (64–75°F)
Temperatures around:
20–22°C (68–72°F)
work particularly well for many captive adults.
In many homes, an aquarium heater is unnecessary.
OVERHEATING
Prolonged excessive temperatures should be avoided.
Water temperatures above approximately:
26°C (79°F)
for extended periods may cause stress.
Never position the aquarium where direct sunlight can cause uncontrolled heating.
Cool, stable water is generally preferable to excessively warm conditions.
WATER PARAMETERS
African Clawed Frogs are adaptable to a reasonable range of water chemistry.
Extreme fluctuations should nevertheless be avoided.
A broadly neutral pH is generally suitable.
Approximately:
pH 6.5–8.0
can be tolerated where conditions remain stable.
Consistency and clean water are generally more important than attempting to achieve an exact pH value.
LIGHTING
African Clawed Frogs do not require intense lighting.
Provide a clear day/night cycle of approximately:
10–12 hours
per day.
Moderate aquarium lighting can support:
- Natural behavioural rhythms
- Live aquatic plants
- Normal environmental cues
Provide shaded areas and hides so frogs can retreat from illumination.
UVB
Because Xenopus laevis is fully aquatic and frequently occupies relatively turbid or sheltered water, strong UVB exposure is inappropriate.
Low-level UVB may be provided as part of a carefully designed captive system, but it is not a substitute for appropriate dietary supplementation.
If UVB is used, exposure should remain low and frogs must be able to retreat beneath:
- Plants
- Hides
- Shaded areas
Strong, unfiltered UV exposure should be avoided.
DIET
African Clawed Frogs are opportunistic carnivores.
A varied captive diet should be provided.
Suitable foods include:
- Quality formulated aquatic frog pellets
- Earthworms
- Appropriate aquatic invertebrates
- Insect larvae
- Small pieces of suitable invertebrate food
- Other nutritionally appropriate aquatic amphibian foods
A high-quality formulated diet can provide a useful nutritional foundation, supplemented with varied whole prey.
BLOODWORMS
Bloodworms are commonly offered to aquatic frogs.
They can be useful as part of a varied diet but should not necessarily form the sole long-term food source.
Dietary variety helps provide a broader nutritional profile.
Frozen foods should be appropriately thawed before feeding.
VERTEBRATE PREY
African Clawed Frogs are capable of consuming:
- Small fish
- Tadpoles
- Other frogs
- Small aquatic vertebrates
However, live feeder fish are unnecessary for routine captive husbandry.
Regular feeder-fish use may introduce:
- Parasites
- Disease
- Nutritional imbalance
- Injury
A varied diet based around quality formulated foods and appropriate invertebrate prey is preferable.
PREY SIZE
Food should be appropriately sized.
African Clawed Frogs have large mouths and extremely strong feeding responses.
They may attempt to swallow inappropriate objects.
Avoid food that is excessively large or difficult to consume.
Substrate and furnishings should also be selected with accidental ingestion in mind.
FEEDING FREQUENCY
Feeding frequency depends upon:
- Age
- Size
- Body condition
- Temperature
- Food type
Juveniles
Growing juveniles can generally be offered appropriately sized food:
Daily or near-daily
with quantities adjusted according to growth.
Adults
Healthy adults can generally be fed:
Approximately 2–3 times per week
depending upon food type and body condition.
Remove uneaten food before it significantly degrades water quality.
BODY CONDITION
African Clawed Frogs are enthusiastic feeders and can become overweight.
Monitor:
- Overall body shape
- Activity
- Mobility
- Weight where practical
- Feeding quantity
Do not use feeding enthusiasm alone to determine appropriate food quantity.
SOCIAL HOUSING
African Clawed Frogs can often be maintained with similarly sized conspecifics.
Significant size differences should be avoided.
Any frog sufficiently small to swallow may potentially be viewed as prey.
Group housing requires sufficient:
- Aquarium space
- Hides
- Feeding opportunities
- Filtration capacity
Animals should be monitored to ensure all individuals are feeding normally.
MIXED-SPECIES HOUSING
A species-specific aquarium is strongly recommended.
African Clawed Frogs should not routinely be maintained with fish or other amphibians.
Potential problems include:
- Predation
- Competition
- Injury
- Disease transmission
- Different environmental requirements
Small fish may be consumed.
Larger or aggressive fish may injure the frogs.
HANDLING
African Clawed Frogs should remain in water whenever possible.
Routine handling is unnecessary.
Their skin is delicate and permeable.
If physical restraint is genuinely necessary, clean powder-free nitrile gloves moistened with aquarium water are recommended.
Never allow the frog to remain out of water unnecessarily.
Transfers are often better performed using a suitable smooth container rather than a net.
NETS
Traditional coarse aquarium nets can potentially damage amphibian skin, toes and limbs.
Where possible, move African Clawed Frogs using:
- Smooth plastic containers
- Appropriate specimen containers
- Very soft amphibian-safe nets where necessary
Any equipment should be clean and free from chemical residues.
BEHAVIOUR
African Clawed Frogs display a range of interesting aquatic behaviours.
They may:
- Rest on the aquarium floor
- Float near the surface
- Explore furnishings
- Search actively for food
- Hide beneath objects
- Surface rapidly for air
They can remain motionless for surprisingly long periods before suddenly becoming active.
Regular surfacing to breathe is completely normal.
BREEDING
African Clawed Frogs reproduce entirely in water.
Males vocalise underwater and use specialised forelimb structures during breeding.
Following amplexus, females can produce large numbers of eggs.
Eggs are deposited throughout the aquatic environment.
Adults may consume eggs and developing larvae.
Captive breeding therefore requires appropriate management if offspring are intended to survive.
TADPOLES
Xenopus tadpoles are unusual compared with many familiar frog larvae.
They remain fully aquatic and require:
- Excellent water quality
- Appropriate food
- Stable temperature
- Adequate space
- Gentle filtration
Larval density must be carefully managed.
As metamorphosis occurs, young frogs remain aquatic and do not require a terrestrial stage.
ENRICHMENT
Although fully aquatic, African Clawed Frogs benefit from environmental complexity.
Suitable enrichment includes:
- Different water depths
- Robust aquatic plants
- Smooth hides
- Large pieces of wood
- Shaded areas
- Open swimming areas
- Varied appropriate foods
The aquarium should allow animals to choose between:
- Open and sheltered locations
- Surface and bottom areas
- Brighter and shaded locations
CLEANING & MAINTENANCE
Regular maintenance should include:
- Removing uneaten food
- Removing visible waste
- Testing water
- Performing partial water changes
- Checking filter operation
- Cleaning filter media appropriately
- Inspecting furnishings
- Checking enclosure security
Biological filter media should generally be cleaned using removed aquarium water rather than untreated chlorinated tap water.
Avoid completely sterilising an established aquarium during routine maintenance.
BIOSECURITY
Biosecurity is particularly important with Xenopus laevis.
The species has historically been associated with the international movement of amphibian pathogens and has established invasive populations outside its native distribution.
Equipment should ideally not be shared between unrelated amphibian systems.
Where equipment must be reused, it should be appropriately cleaned and disinfected.
Never release:
- Frogs
- Tadpoles
- Eggs
- Aquarium plants
- Aquarium water
- Biological material
into the natural environment.
INVASIVE SPECIES CONSIDERATIONS
African Clawed Frogs have established invasive populations in several regions outside their natural range.
Their ability to tolerate varied environmental conditions makes accidental or deliberate release particularly irresponsible.
Before acquiring Xenopus laevis, keepers should check current legislation in their jurisdiction.
Restrictions may apply to:
- Possession
- Importation
- Transport
- Sale
- Breeding
depending upon location.
QUARANTINE
New African Clawed Frogs should undergo appropriate quarantine before entering an established collection.
Monitor:
- Appetite
- Weight
- Skin condition
- Swimming
- Buoyancy
- Faeces
- General behaviour
Separate equipment should ideally be used during quarantine.
Veterinary assessment and diagnostic testing should be considered where health concerns exist.
HEALTH
Potential health problems include:
- Bacterial infections
- Fungal infections
- Parasitic disease
- Skin lesions
- Nutritional deficiencies
- Obesity
- Trauma
- Water quality-related disease
Warning signs include:
- Persistent refusal to feed
- Unexplained weight loss
- Severe bloating
- Persistent abnormal floating
- Difficulty swimming
- Skin discolouration
- Redness
- Open sores
- Abnormal posture
- Unusual lethargy
Water quality should be checked immediately whenever abnormal behaviour or skin changes occur.
Persistent or serious health concerns should be assessed by a suitably experienced exotic or amphibian veterinarian.
LONG-TERM CONSIDERATIONS
African Clawed Frogs are frequently regarded as straightforward aquatic amphibians.
Their hardiness should not be mistaken for an ability to thrive in poor conditions.
Long-term care requires:
- A properly established aquarium
- Excellent water quality
- Biological filtration
- Appropriate temperatures
- A varied diet
- Secure containment
- Regular maintenance
- Veterinary access
They can also be exceptionally long-lived.
Potential keepers should therefore be prepared for a commitment potentially extending for 15–20 years or more.
A well-maintained aquarium provides an excellent opportunity to observe the unusual behaviour of a completely aquatic frog.
