Identification
Adults have smooth oval shells in dark brown to black. The lips and skin around the jaws are pale. The plastron is yellow. A small spine at the tail tip is normal. Males are larger, with broader heads and longer thicker tails.
Natural Range and Habitat
This species comes from Central and South America. It occurs in southern Mexico, Nicaragua, Colombia, Ecuador, and north west Peru. It favors slow water like swamps, marsh edges, quiet creeks, and silty ponds. It will walk along the bottom in the shallows and bury in soft sand when water drops.

Tank Size and Water Depth
Plan on a 40 gallon breeder tank for one adult. For two, use at least a 55 to 75 gallon tank. Give water deep enough to submerge with ease. A good rule is water depth at least one to one and a half times the shell length, with ramps and resting spots.
Add a small land shelf or dock for basking. They bask with the head out often. A giant beach is not needed, but a safe dry spot is helpful. See our turtle tank setup guide and best turtle dock picks.
Filtration and Water Quality
They are messy eaters, so strong filtration is a must. Use a canister filter rated for at least twice your tank volume. Do partial water changes of 25 to 40 percent each week. Keep ammonia and nitrite at zero and keep nitrate as low as you can.
Use dechlorinated water. Smooth sand or large river stones are fine if you want a substrate. Avoid small gravel that can be swallowed. For gear ideas, check our best filter for turtle tanks.
Heat, UVB, and Lighting
Water can sit at 72 to 78 °F in most homes. Use a heater only if your room runs cool. The basking spot should sit at 88 to 92 °F. Place a digital thermometer at the dock and one in the water.
Provide UVB for shell and bone health. A T5 5.0 or 10.0 tube over the dock works well. Run lights on a 12 hour cycle. Our UVB bulb guide explains placement and height.
Decor, Hides, and Plants
Add driftwood, cork flats, or rock caves so your turtle can retreat. Keep stacks stable. Live or artificial plants give cover and cut stress. Leave open lanes for swimming.
Feeding and Schedule
In the wild they eat snails, insects, small fish, shrimp, and some plants. In captivity use a base of quality turtle pellets, then rotate proteins and greens. Offer food in the water. Many keepers feed in a tub to limit mess.
- Good proteins: earthworms, nightcrawlers, crickets, roaches, snails, freshwater shrimp, small fish pieces, cooked mussel
- Greens: dandelion greens, collard greens, red leaf lettuce, duckweed, water lettuce trimmings
- Pellets: a staple from a trusted brand sized for aquatic turtles
- Supplements: a pinch of calcium once per week on greens
Simple Feeding Schedule
| Age | How often | Portion |
|---|---|---|
| Hatchlings to 6 months | Daily | As much as they eat in 10 minutes |
| Juveniles | Every other day | Pellets plus one fresh item |
| Adults | 2 to 3 times per week | Pellets one meal, mixed proteins the next, greens once per week |
Tank Mates and Behavior
White Lipped Mud Turtles are alert and bold, but they do not enjoy handling. They may nip during feeding. They can cohabit with another mud turtle in a large tank with many hides. Watch for bullying. Fish can work if they are fast and too large to swallow, but there is always some risk.
Learn the basics of layout and stocking in our turtle tank setup guide.
Health and Common Issues
Clean water and UVB prevent most problems. Watch for cloudy eyes, soft shell, swollen ear abscess, wheezing, or fungus on the skin. Fix basics first. Improve filtration, test water, and check your lamp age and distance. Learn more in our guides on metabolic bone disease, ear infections, shedding, and parasites.
Breeding Basics
Pairs can breed late summer in many areas. Clutches hold one to five eggs placed under leaf litter or in a shallow nest. Incubation can run three to nine months depending on temperature.
Captive Bred Only
Choose captive bred animals from trusted sellers and follow local laws. Price varies by age. Some reputable options include The Turtle Source.
Mud Turtle vs Musk Turtle
Look at the plastron. Mud turtles have a larger plastron with two hinges. Musk turtles have a small plastron and a slimmer build.
Frequently Asked Questions
Do White Lipped Mud Turtles need a water heater?
Only if your room runs cool. Keep water at 72 to 78 °F. Use a heater if it dips below that range.
How big do they get?

Can they live with fish?
Sometimes. Choose fast fish that are too big to swallow and give many hides. There is always some risk.
How deep should the water be?
Aim for at least one to one and a half times the shell length, with ramps and shallow rests.
Are they good for beginners?
They are better for an intermediate keeper. Clean water and correct UVB are key to success.
Pros and Cons
- Pros: small size, active, simple dock, flexible diet
- Cons: messy eater, does not enjoy handling, needs strong filtration and UVB
Conclusion
White Lipped Mud Turtles are hardy and engaging if you keep water clean and lighting correct. Give a roomy tank, a small basking dock, strong filtration, and a balanced diet. Keep handling light and enjoy a lively little turtle for many years.
