Reptiles & amphibians
Softshell turtle
Chinese (Japanese) softshell turtle and other softshell species
Most important: Soft shell is prone to skin disease; clean water is life
Basics
- Lifespan
- 20-30+ years; records of 40 years in captivity
- Weight
- Adults 1-3 kg; females grow to over 30 cm shell length
- Temperament
- Timid and nervous. When startled, bites fast and hard
- Care difficulty
- High (water quality, skin disease, bite risk)
- Legal status
- Act on Welfare and Management of Animals. Abandonment and release are prohibited; take care when rehoming non-native species
- Key point
- Soft shell is prone to skin disease; clean water is life
Ecology & traits
- Body
- Shell is covered in skin and soft. Long snout used to breathe at the surface. Can also breathe underwater through the throat lining
- Origin & range
- The Japanese softshell is native to Honshu and southward and East Asia. Non-native species come from China and North America
- Wild habitat
- Muddy bottoms of slow rivers, ponds and rice paddies. Lives buried in sand or mud
- Activity & sleep
- Mostly diurnal but also active at night. Hibernates buried in mud from October to April
- Social behavior & people
- Solitary and strongly territorial. Housing together leads to biting
Characteristic behaviors
- Buries itself in sand with only the snout exposed, lying in ambush
- Neck extends more than half the shell length and can bite backward
- Basks on land but is very wary and flees at any noise
Common illnesses: warning signs & prevention
Water mold / skin fungal infection
SignsWhite cotton-like growth on skin or shell, sodden skin, red sores, loss of appetite
PreventionFrequent water changes, a dry basking area and sunlight, treat shell wounds immediately
Shell ulcers / skin ulcers
SignsShell edge or skin looks melted away, red pits, foul odor, bleeding
PreventionAvoid dirty water where bacteria multiply, no sharp rocks or driftwood, see a vet early
Metabolic bone disease (rickets)
SignsWavy shell edge, shell dents when pressed, trembling limbs, weak bite
PreventionFeed whole small fish and shrimp with bones; use calcium powder together with a UVB lamp
Pneumonia / respiratory infection
SignsFloats tilted at the surface, open-mouth breathing, nasal discharge or bubbles, noise from the snout
PreventionReduce the gap between water and air temperature; hibernate only healthy adults, if at all
Egg binding (dystocia)
SignsFemale tries to dig on land, strains, loses appetite, hind legs stop moving
PreventionKeep a moist sand nesting area at all times, prevent calcium deficiency; females lay even when kept alone
Parasites / digestive disease
SignsDiarrhea, worms in feces, refusing food, weight loss, persistent mud-like feces
PreventionDo not feed raw wild-caught fish or insects; get a fecal exam after purchase
Warning-sign checklist
Check once a day. If even one applies, contact an animal hospital early.
First aid for illness
White cotton or sores
Change all the water and dry the turtle in a clean dry container for a few hours a day. Do not add salt or medication on your own; see a vet within a few days
Open-mouth breathing, nasal discharge
Suspect pneumonia. Move to shallow water where the snout reaches the surface easily, keep the surroundings at 28-30°C and see a vet the same day
Soft shell
Suspect rickets. Avoid falls and pressure; check the UVB lamp and calcium. It will not heal on its own; see a vet early
Prolonged refusal of food
If water is below 25°C, raise it to 28°C and add hiding places. See a vet if it lasts 1 week in adults or 2 days in juveniles
Common injuries: prevention & first aid
Shell or skin lacerations
PreventionNo sharp rocks or broken heaters, do not keep multiple turtles together, do not catch with a net
First aidDo not return to water; apply pressure with clean gauze, keep warm in a dry container and see a vet the same day
Bite wounds to snout or neck
PreventionDo not house together, feed with tongs so fingers are not mistaken for food, do not startle through the glass
First aidApply pressure to bleeding; a damaged snout directly affects breathing, so see a vet the same day
Flipped onto its back
PreventionProvide deep water and sand to bury in, keep land-area steps low, and enough space to right itself
First aidTurn it over immediately. The flat shell makes righting hard and suffocation likely; if limp, keep warm and see a vet
Burns (heater)
PreventionFit a heater guard, secure it where it cannot be buried in sand, keep a thermometer in place
First aidCool the area with clean water without letting it dry out, apply no ointment and see a vet the same day
Zoonoses (diseases that can spread to people)
Salmonellosis
RouteOral infection from hands that touched the body, feces or tank water
PreventionWash hands with soap after handling, never wash the tank in the kitchen, keep infants and toddlers away
Aeromonas infection
RouteDirty tank water entering a cut on the hand
PreventionWear gloves for water changes, do not touch the water with cuts, see a doctor if swelling appears
Leptospirosis
RouteTank water, mud or urine contacting wounds or mucous membranes
PreventionWear goggles and gloves when changing mud or sand; see a doctor for fever or muscle pain
Dermatophytosis (ringworm)
RouteTouching a turtle with skin disease or its tank
PreventionDo not handle sick animals bare-handed, do not share equipment, see a doctor for ring-shaped red patches on skin
Husbandry: food, water, toys, nest, bedding
Food
- Mainly animal protein: frozen small fish, shrimp, shellfish, insects; juveniles daily
- Adults every 2-3 days, roughly the size of the head as a guide
- Add softshell turtle pellets to supplement calcium
Water
- Tank water is the drinking water. Dechlorinate, use a filter and change water at least twice a week
- Except during hibernation keep water at 25-30°C and avoid sudden changes
Never feed
- Raw wild-caught fish or insects (parasites, pesticides)
- Fatty meat, processed food, bread (indigestion)
- Frozen food still cold (indigestion, regurgitation)
Toys & play
- Fine sand deep enough to bury in, to recreate ambush behavior
- Add live shrimp or small fish to chase
- Add a gentle current and keep room to swim
Nest, bed & hideout
- A spot to bury in sand is the best hiding place
- Underwater tubes or the shade of driftwood; land area along the wall
Bedding & litter
- Fine river sand 5 cm or deeper; no angular gravel
- In a bare tank, use a pot or shelter as a hiding place instead
- Provide a moist sand area on land for egg laying
Housing: cage, exercise, temperature & humidity
Cage / housing material
Glass aquarium or plastic tub, lid weighted down
Size & space
At least 4 x 3 times the shell length; 90-120 cm tank for adults
Layout
- Water depth 1.5-2 times the shell length, plus a shallow area where the snout reaches the surface
- Sand to bury in and a dry land area; UVB lamp above the land area
- Heater with a guard, placed where it cannot be buried in sand
Placement notes
- Avoid windowsills where direct sun spikes the water temperature
- Noisy or vibrating locations cause food refusal
Exercise, free-roam & walks
- Loose in a room it escapes, falls, and the dry air damages its skin
- Bask on the in-tank land area or in a fenced shallow container under supervision
- Surprisingly fast on land; always keep within arm's reach
Temperature & humidity
TemperatureWater 25-30°C, land area around 32°C, never below 25°C in winter
HumidityAquatic, so humidity is not needed; the land area should be able to dry out
Summer & winter
- Summer: appetite drops above 30°C; change water, shade the tank, increase water volume
- Winter: heat with a heater; in captivity it is safer not to hibernate
Grooming & protection from predators
Nail trimming
Usually not needed; worn down on land-area rocks. If overgrown and snagging, have the vet trim them
Brushing, skin & coat care
Do not scrub shell or skin. Cotton-like growth goes to the vet; at most rinse lightly with lukewarm water
Other care
Shedding as thin peeling skin is normal; see a vet for snout wounds or an overgrown beak
Protection from predators
- Crows, herons, raccoons: outdoors use a wire-mesh lid with weights
- Dogs and cats: do not let them reach into the tank
- Housing with large fish or other turtles causes bites and infection
Care precautions (accident prevention)
Foreign-body ingestion
Swallows gravel and pebbles with food, causing intestinal blockage. Use fine sand and feed with tongs near the surface
Being stepped on
Stepped on while loose in a room, the soft shell is crushed and organs are damaged. Never let it loose on the floor; move it in a lidded container
Getting pinched
Snout or neck gets caught in gaps in the lid or land area and it cannot breathe. Secure the lid with no gaps and close gaps between the land area and the wall
Falls
Falling from a desk or tank stand cracks the shell. Support the belly with both hands, keep the head away from your body and carry only short distances
Escape
Climbs even vertical glass and pushes the lid open to escape. Weight the lid; if it escapes, search water sources, shadows and dark gaps, and rescue it before it dries out
How to safely release a bite
Never do this
- Pull to yank it off (skin tears deeply)
- Hit the shell, swing it around, or grab the neck
Safe release procedure
- Stay still and quiet; the more you struggle, the harder it bites
- Put the turtle in water with your hand; most open their mouths underwater
- Without water, pour lukewarm water over the snout and corners of the mouth
- If it will not let go, gently insert a wooden stick at the back of the jaw to pry it open
After the release
Rinse under running water for 5 minutes and apply pressure. See a doctor for deep wounds, finger deformity, swelling or fever
Emergency care manual
Go to an emergency vet now (life-threatening)
- Cracked shell, exposed organs, heavy bleeding
- Limp and motionless with mouth open
- Drowned, motionless underwater, vomiting water
- Heater burns, left flipped over for a long time
See a vet the same day
- Open-mouth breathing, nasal discharge, floating tilted
- Skin or shell suddenly red and melting, foul odor
- Looks ready to lay eggs and strains but nothing comes out
What to tell the vet & what to bring
Species, shell length, weight, water temperature and setup, diet, photos of feces and the affected area, onset date; confirm in advance that the clinic sees reptiles
Checking consciousness, breathing & heartbeat
- Response: touch the snout or limbs and see if it withdraws
- Breathing: movement of throat and snout; normally a few times per minute
- Heartbeat: fingertip at the base of the neck; extremely slow when cold
Resuscitation steps
- Wrap in a wet towel and warm to 28-30°C to restore metabolism
- If drowned, hold by the hind legs head down to drain water
- Extend the neck and move the front legs in and out to work the chest
- Continue for several minutes while transporting; recovery from apparent death is possible
Stopping bleeding
- Apply pressure with clean gauze for 5 minutes or more
- Keep the wound out of water and dry on the way to the vet
- Do not use antiseptics or styptics on your own
Transport
- Lidded container lined with cloth; wrap heat packs in cloth, never apply directly
- No water; a wet towel keeps the skin from drying out
