How To Take Care Of Mud Turtles | Foolproof Care Sheet

You know those tiny, grumpy-looking turtles that seem like they’re perpetually having a bad day? Meet the mud turtle – nature’s most underrated aquatic roommate.

Don’t let their cranky expression fool you though, because these little guys are about to become your new favorite pet obsession.

Picture this: you want a turtle that’s small enough to fit in a reasonable tank but tough enough to live for 50+ years.

That’s literally half a century of turtle companionship! Most people think they need some massive setup for an aquatic turtle, but mud turtles are breaking all the rules here.

What Makes Mud Turtles Special

These aren’t your typical “sit on a log and look pretty” turtles.

Mud turtles rarely grow over 5 inches long, making them one of the smallest aquatic turtles, and they’re semi-terrestrial, meaning they live both on land and in water.

Think of them as the introverts of the turtle world – they’d rather walk along the bottom of their tank than show off with fancy swimming moves.

Here’s the weird part: they often bury themselves in wet leaves or loam in captivity because they literally love mud. It’s like having a pet that comes with built-in gardening skills.

The most common species you’ll find are the Eastern Mud Turtle and the Three-Striped Mud Turtle.

The Eastern has a smooth, keelless shell that’s olive to dark brown with only 11 marginal plates instead of the usual 12, while the Three-Striped variety shows off some nice yellow racing stripes.

Tank Setup That Actually Works

Tank Size Requirements

Wrong! Don’t fall for the “small turtle, small tank” myth.

You’ll want at least a 40-gallon tank for one turtle, 50-100 gallons for the typically larger females.

Think of it like apartment hunting – sure, you could live in a studio, but wouldn’t you rather have space to actually move around?

The minimum for appropriately keeping one adult mud turtle is 75 gallons, or roughly 48″L x 18″W x 21″H.

Some experts suggest using Waterland tubs instead of traditional aquariums because they give you that perfect half-land, half-water setup without the engineering headache.

Water and Land Setup

Here’s where it gets interesting: the habitat should be half land and half water, with water depth deep enough for the turtle to fully submerge and turn around, but also to be able to easily reach the surface to breathe.

For a mud turtle, a water depth of 6 to 10 inches is generally ideal, but this can vary depending on the specific turtle’s size. They are natural bottom-walkers and prefer to have a secure footing.

The land portion needs to be legit – not just a tiny basking platform. Mud turtles spend a significant amount of time on land and like to burrow, so it’s important to have an area of ~10″ of sandy soil within easy access at all times.

Substrate Options

Option	Pros	Cons
Bare bottom	Easy to clean, no impaction risk	Less natural, boring
Large river stones	Natural look, can’t be eaten	More cleaning required
Sand/soil mix	Perfect for burrowing	Harder to maintain

With mud turtles, it’s recommended to have a bare tank bottom or with large river stones larger than the animal can consume accidentally.

Temperature and Lighting Setup

Water Temperature

Water temperature should be maintained at 74-78°F, with most sources agreeing on 75-78°F as the sweet spot. Some sources suggest 70-75°F for Eastern Mud turtles specifically.

Air Temperatures

Ambient tank temperature should be between 78-82°F, while the basking area should reach 86-92°F.

Use a good aquarium heater for the water and position basking bulbs carefully. Avoid ceramic heat emitters, red bulbs, or blue bulbs, as these are not as effective.

UVB Lighting Requirements

Plot twist: UVB is a necessity for a healthy turtle, with indoor turtles requiring UVB lighting for 10-12 hours a day.

Lights should be on for 14 hours/day during summer and 10 hours/day during winter.

Remember to replace UVB bulbs regularly, even if they still look bright, as their UVB output diminishes over time.

A T8 UVB bulb should be replaced every 6 months, while a more modern and powerful T5 UVB bulb can last up to 12 months before needing replacement.

Always check the manufacturer’s specific recommendations for the bulb you purchase.

Water Quality and Filtration

Here’s where people mess up big time.

You need a canister-style filter capable of handling at least 2x the amount of water in the enclosure. So for a 75-gallon setup, you need a filter rated for 150+ gallons.

Make sure the filter is low-flow for minimal water disturbance — a strong current will stress your turtle!

Change a third of the water once a week to keep the water clean, and maintain pH between 6.6-7.6.

Feeding Your Mud Turtle

Diet Breakdown

Mud turtles are basically the carnivores of the small turtle world. This species is highly carnivorous, preferring to consume fresh water fish (not goldfish) and earthworms in captivity as adults.

Daily Feeding Schedule:

• Feed protein meals every other day and leafy greens daily
• Hatchlings are fed two times a day as much as they will eat in 10-15 minutes, while adults are fed once a day for 10-15 minutes

Portion Sizes

A portion of animal-based food should be roughly the same size as the turtle’s head. While mud turtles may not always be enthusiastic about greens, it’s important to offer them.

A small amount of vegetable matter, roughly the size of the turtle’s head, should be provided daily or every other day.

Best Foods

Protein Options:

• Crickets, earthworms, dubia roaches, shrimp/krill, bloodworms, silkworms, snails, grasshoppers, clams, quail eggs, pre-killed feeder fish

Vegetables:

• Dark green leafy vegetables (avoid iceberg or romaine lettuce)
• Collard greens, dandelion greens, endive, green leaf lettuce, kale, red leaf lettuce

Commercial Pellets:

• Omega One Juvenile Turtle Pellets, Tetra ReptoMin, Zoo Med Natural Aquatic Turtle Food, Mazuri Aquatic Turtle Diet

Feeding Tips from Real Owners

The weirdest part? Baby turtles need plants to hide in or they will feel stressed and simply not eat – they’ll starve themselves to death.

Some babies are incredibly picky and will only eat if food is wriggling or looks like it used to be alive.

One frustrated owner mentioned their baby turtle would only eat dried red river shrimp and small pieces of red wigglers, refusing everything else for weeks!

Handling and Behavior

Temperament

Let’s be real here: these strange little creatures can occasionally get grouchy, so they’re typically recommended for owners with some experience in reptile habitats.

Mud turtles will secrete a foul-smelling musk when alarmed, and it’s best to keep handling to a minimum. Think of them as the grumpy old neighbors of the turtle world – they’re fine if you respect their space.

Social Needs

It’s best not to house multiple mud turtles in the same enclosure, as they can be aggressive toward other turtles in their “territory” — this is particularly true for males.

These are definitely loners who prefer their own space. Kind of like me on Monday mornings, honestly.

Common Mistakes to Avoid

Water Temperature Errors

Some beginners keep water too warm – mud turtles do better with water in the mid to high 70s, not the 80s. Too hot and they get stressed; too cold and they won’t eat.

Substrate Disasters

Never use small gravel or anything they can swallow. Large river stones should be larger than the animal can consume accidentally.

Filtration Failures

An under gravel filter is not enough filtration to maintain a clean environment and will need to be supplemented with other filtration devices.

Feeding Mistakes

Don’t make the rookie mistake of removing them from their tank to feed. Try feeding the turtle in its normal enclosure instead of removing it and putting it in something else to eat.

Health and Lifespan

Expected Lifespan

With proper care, mud turtles can live for up to 50 years in captivity. That’s not a commitment you make lightly – this turtle might outlive your car, your mortgage, and possibly your favorite streaming service.

Health Warning Signs

Pinkish skin, a pinkish plastron, and puffy skin or eyes are signs that the water quality is poor. Those species naturally found in clear, oxygenated streams often exhibit eye and skin problems if kept in unclean water.

Vitamin Requirements

Like all basking turtles, mud and musk turtles are susceptible to vitamin A and D3 deficiencies. This is why that UVB lighting isn’t optional – it’s literally keeping your turtle’s bones from dissolving.

Final Thoughts

Mud turtles are basically the perfect compromise between “I want a cool aquatic pet” and “I don’t want to dedicate my entire living room to a turtle pond.”

They’re small enough to be manageable but interesting enough to keep you entertained for decades.

Sure, they’re a bit grumpy and they’ll never be cuddly, but there’s something deeply satisfying about watching a tiny turtle that’s older than most of your houseplants methodically explore every corner of its habitat.

The key is respecting what they actually need instead of what we think they need.

Give them proper water quality, the right temperatures, plenty of space to both swim and hide, and you’ll have a fascinating companion that’ll be around long enough to judge all your future life decisions.
