Raising a musk turtle (commonly the Common Musk Turtle, Sternotherus odoratus, also called a "stinkpot") is a rewarding experience for reptile enthusiasts. These small, mostly aquatic turtles are hardy and long-lived but have specific care requirements.
Size: Adults reach 3–5 inches (7.5–12.5 cm)
Lifespan: 30–50+ years in captivity
Temperament: Shy, solitary, and may release a foul-smelling musk when stressed (hence the name)
Activity: Primarily aquatic; rarely basks but still needs proper lighting
Origin: Freshwater habitats in North America—slow-moving streams, ponds, and marshes with soft bottoms
Tank Size
Hatchlings: 10–20 gallon tank
Adults: Minimum 40 gallons (long-style preferred); 55–75 gallons ideal
Water Depth: 6–10 inches (they’re bottom-walkers, not strong swimmers—avoid overly deep water)
💡 Note: Musk turtles spend >90% of their time underwater and rarely bask, but UVB access is still essential for health.
Indoor vs. Outdoor
Indoor: Best for most keepers—easier to control temperature and safety
Outdoor: Only in warm, secure ponds (USDA zones 7–10); must include shaded areas and shallow zones
Water Quality
Use dechlorinated water (tap water treated with reptile-safe conditioner)
Install a high-quality filter (canister or sponge)—musk turtles produce a lot of waste
Perform 25–30% water changes weekly
Temperature
Water: 72–78°F (22–26°C)
Use a submersible aquarium heater with a protective guard
Ambient air: 75–80°F
Basking area (optional but recommended):
82–88°F (28–31°C)
Provide a small platform or floating dock—even if rarely used
Lighting
UVB lighting is CRITICAL—despite minimal basking, they still need UVB to metabolize calcium
Use a 5.0 or 6% linear UVB tube (e.g., ZooMed ReptiSun or Arcadia)
Mount over the basking area or screen top; replace every 6–12 months
Photoperiod: 10–12 hours of light per day (use a timer)
Substrate & Enrichment
Substrate: Fine sand or smooth gravel (they like to forage on the bottom)
Hiding spots: Essential! Use clay pots, PVC pipes, driftwood, or commercial caves
Plants: Hardy live plants (e.g., java fern, anubias) or silk plants for cover
Leaf litter: Optional—adds natural tannins and foraging enrichment
Musk turtles are carnivorous throughout life—unlike many turtles that become more herbivorous with age.
Diet
Staple foods:
Earthworms, blackworms, bloodworms, chopped nightcrawlers
Small snails, freshwater shrimp, daphnia
Occasional small fish (e.g., guppies)
Commercial foods: High-protein turtle pellets (e.g., Mazuri Aquatic Turtle Diet, ReptoMin)
Avoid: Fatty meats, processed foods, or excessive dried shrimp
Feeding Schedule
Juveniles: Daily
Adults: Every other day
Always feed in water—they need it to swallow
Supplements
Dust food with calcium (without D3 if using UVB) 2–3 times/week
Multivitamin once weekly
Musk secretion: Normal defense—handle minimally to reduce stress
Biting: Possible if threatened; use feeding tongs
Common health issues:
Shell rot (from poor water quality)
Vitamin A deficiency (swollen eyes)
Metabolic Bone Disease (from lack of UVB/calcium)
Veterinary care: Find an exotic/reptile vet for check-ups or illness
Do not house with fish or other turtles—they may nip or compete for food
Avoid overhandling—they’re observation pets, not cuddly companions
Never release into the wild—it’s illegal and dangerous to ecosystems
Check local laws: Some states restrict native turtle ownership
With proper care, a musk turtle can thrive for decades and offer fascinating underwater behavior to observe. Always prioritize water quality, UVB exposure, and a species-appropriate diet.
