Frequently asked questions
How big do musk turtles get?
3-5 inches shell length as adults. Small enough that a 40-gallon breeder tank works for a single adult; many keepers use larger.
How long do musk turtles live?
30-50 years with proper care. Some individuals exceed 60. Long commitment for an apartment-friendly pet.
Do musk turtles bite?
Yes — bites are powerful for the body size and the neck reaches far back. Handling is limited; supervised contact only.
Why do musk turtles smell bad?
When threatened they release a musk from glands near the rear legs. In well-kept captive animals this is rare; aggressive handling or housing stress triggers it.
Can musk turtles live with fish?
Mostly no. Adult musk turtles eat small fish. Large peaceful fish (8+ inches) may survive but aren't reliable tank mates.
