Common musk turtle (stinkpot)
Sternotherus odoratus · also called Stinkpot, Eastern musk turtle, Common stinkpot
A tiny, highly aquatic North American turtle named for the musky odor it releases when threatened. Hardy, long-lived, and well-suited to smaller aquariums, it is one of the best beginner aquatic turtles.

Part of the Freshwater turtles
Aquatic and semi-aquatic turtles kept in heated, filtered aquariums or ponds with basking areas, UVB, and clean water — from tiny musk turtles to large sliders.
Habitat & space requirements
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.
Habitat & enclosure
Highly aquatic bottom-walker that rarely basks for long. A single adult needs a minimum 75-115 L (20-30 gallon) aquarium; bigger is better. Keep water depth moderate (roughly 1.5-2x the shell length up to ~30 cm) since they are mediocre swimmers and walk along the bottom — provide gentle slopes, driftwood, and plants so they can reach the surface to breathe. Water temperature 22-26°C (72-78°F); a small basking spot at 30-32°C (86-90°F) with low-output UVB is recommended even though basking is brief. Always provide a haul-out option to prevent drowning.
Substrate
Bare-bottom is easiest to keep clean, or use smooth river-rounded gravel too large to swallow, or fine sand for a natural bottom-walker setup. Avoid small gravel that can cause impaction. Include plenty of submerged hides (driftwood, caves, dense plants).
Equipment & setup
Canister or strong hang-on-back filter rated above tank volume (turtles are messy). Submersible heater (guarded) for 22-26°C water. Low/medium-output UVB (5.0) over a small basking platform plus a low-wattage basking lamp. Secure lid — they can climb decor. Thermometer; regular water changes.
Diet
Opportunistic carnivore/omnivore. Offer a quality aquatic-turtle pellet as a base plus protein items: earthworms, bloodworms, snails, crayfish, small feeder insects, and occasional lean fish. Snails and other hard-shelled prey help wear the beak. Adults eat less frequently (every 2-3 days); juveniles daily. Avoid overfeeding — obesity is common in captivity.
Behavior & temperament
Defensive when first handled — true to the 'stinkpot' name, it secretes a foul musk from glands at the shell edge and may bite with a surprisingly long, flexible neck that can reach the back legs. Most calm down with regular gentle handling but remain a watch-don't-handle species. Largely nocturnal/crepuscular and spends days hiding under cover or walking the substrate.
Health
Hardy if water quality is maintained. Common issues stem from poor filtration: shell rot, ammonia/skin infections, and ear abscesses (linked to dirty water and vitamin A deficiency). Provide UVB and a varied diet to prevent metabolic bone disease and beak overgrowth. Respiratory infections occur if water is too cold. Like all turtles they can carry Salmonella — wash hands after contact. Quarantine new animals.
Tips, DIY & hacks
Keep water depth shallow enough that the turtle can rest on a perch and reach the surface easily — drowning is the top husbandry risk. They are escape-prone climbers, so any emergent decor must not form a ladder to the rim. House singly; multiple males fight. Hardy enough to tolerate beginner mistakes, which is why they're a great first aquatic turtle.
