In this complete map turtle species guide, we’ll dive deep into everything you need to know. We’ll explore the most popular species to help you choose the right one, build their perfect enclosure from the ground up, master their diet, and learn how to spot common health problems before they become serious. Let’s get started!
What Are Map Turtles? The Living Cartographers of Your Aquarium
Before we jump into the specifics, let’s get to know these amazing animals. “Map turtle” isn’t just one type of turtle; it refers to the entire Graptemys genus. They get their name from the delicate, map-like markings on their carapace (the top shell), which are unique to each individual.
Native to the rivers and large lakes of North America, these turtles are built for an aquatic life. They are strong swimmers and spend a huge portion of their day in the water. But one of their most defining behaviors is basking—you’ll often see them hauled out on logs or rocks, soaking up the sun.
One of the most crucial things to understand right away is sexual dimorphism. This is a fancy term meaning that males and females of the same species look very different. In map turtles, the females grow significantly larger than the males—often two to three times the size! This is a critical factor when planning your tank size.
Popular Map Turtle Species for Your Aquarium: A Closer Look
While there are many types of map turtles, a few are more commonly and responsibly available in the pet trade. Getting to know them is the first step. Here are some of the most popular choices for enthusiasts.
The Northern Map Turtle (Graptemys geographica)
This is the “original” map turtle that gave the genus its name. They have beautiful, olive-green shells with faint yellow lines. They are one of the more widely distributed species in the wild.
- Adult Size: Males 4-6 inches, Females 7-10 inches.
- Temperament: Generally shy and can be easily stressed by excessive handling. They prefer to be watched, not held.
- Difficulty: Beginner to Intermediate. Their needs are straightforward, but their timid nature requires a calm environment.
The Mississippi Map Turtle (Graptemys pseudogeographica kohni)
Easily one of the most popular in the hobby, the Mississippi Map is known for its prominent, saw-toothed keel along its spine and striking yellow crescents behind its eyes. They are active and fascinating to watch.
- Adult Size: Males 3.5-5 inches, Females 6-10 inches.
- Temperament: A bit more outgoing than Northerns, but still skittish. They will quickly dive into the water if they feel threatened.
- Difficulty: Great for beginners. They are hardy and adapt well to captivity when given proper care.
The False Map Turtle (Graptemys pseudogeographica)
Closely related to the Mississippi Map, the False Map Turtle has a backward-facing yellow “L” shape behind its eye instead of a crescent. They share a similar sawback appearance and are just as active in the aquarium.
- Adult Size: Males 3.5-5.5 inches, Females 5-9 inches.
- Temperament: Very similar to the Mississippi Map—active swimmers and enthusiastic baskers.
- Difficulty: Beginner-friendly. Their care is nearly identical to that of their Mississippi cousins.
Setting Up the Perfect Habitat: A Map Turtle Species Care Guide
Creating the right environment is the most important part of keeping your turtle healthy and happy. This is where you can really shine as an aquarist. Here are the map turtle species best practices for building their home.
Tank Size: Plan for the Future
This is not the place to cut corners. While a baby map turtle is tiny, they grow quickly. A common rule of thumb is 10 gallons of water per inch of shell length, but I always advise aiming for more.
Since females get so large, a single adult female will need a minimum of a 75-gallon tank, with a 125-gallon being even better. A male can live comfortably in a 40- or 55-gallon tank. Always plan your tank size for the turtle’s adult size, not the size it is when you buy it.
Water Quality is Everything
Map turtles are river animals, which means they are used to clean, moving water. They are also messy eaters and produce a lot of waste. This combination means you need a powerful filter.
Forget the standard hang-on-back filter you use for fish. You need a canister filter rated for at least double your tank’s volume. For a 75-gallon turtle tank, get a filter rated for 150 gallons or more. You’ll also need to perform partial water changes (25-50%) every week to keep nitrates down.
The All-Important Basking Dock
Your turtle needs a place to get completely out of the water and dry off. This is non-negotiable. Basking allows them to regulate their body temperature, absorb crucial UVB light, and prevent shell and skin infections.
The basking area must be large enough for the turtle to fit its entire body and stable enough not to tip. You can use floating docks, above-tank basking platforms, or build your own with rocks and driftwood. The key is that it’s easily accessible for your turtle.
Essential Lighting: UVB and Heat
This is another area where there is no room for compromise. Your turtle needs two specific types of light over its basking spot:
- A Heat Lamp: This creates a warm spot for basking. The surface temperature of the basking dock should be around 90-95°F (32-35°C). Use a digital probe thermometer to check it.
- A UVB Lamp: This is arguably the most critical piece of equipment. Turtles need UVB light to synthesize Vitamin D3, which allows them to process calcium. Without it, they will develop serious and fatal conditions like Metabolic Bone Disease (MBD). Use a high-quality UVB bulb (like a T5 HO linear fluorescent or a mercury vapor bulb) and replace it every 6-12 months as directed by the manufacturer, as the UVB output degrades over time.
The rest of the tank’s water temperature should be kept around 74-76°F (23-24°C) using a submersible aquarium heater.
Feeding Your Map Turtle: Diet and Nutrition Best Practices
Understanding how to map turtle species feeding works is key to their long-term health. They are omnivores, but their dietary preferences change as they age.
Hatchlings and juveniles are primarily carnivorous, needing lots of protein to grow. Adults become more omnivorous, incorporating more plant matter into their diet. A balanced diet is crucial.
Here’s a great weekly feeding plan:
- High-Quality Pellets (Staple): Feed a quality commercial turtle pellet (like Mazuri or Zoo Med) 3-4 times a week. This should make up about 50% of their diet.
- Protein Sources: Offer feeder insects like crickets, dubia roaches, and occasional mealworms. You can also offer dried shrimp or krill as a treat.
- Leafy Greens: Offer greens like red leaf lettuce, dandelion greens, and turnip greens several times a week. You can use a suction-cup veggie clip to keep it in one place. Avoid iceberg lettuce as it has no nutritional value.
- Calcium Source: It’s a great idea to keep a cuttlebone in the tank at all times. The turtle will nibble on it as needed, which provides essential calcium and helps keep its beak trimmed.
Pro Tip: Feed your turtle in a separate, small container of water. This keeps your main tank dramatically cleaner and reduces the load on your filter!
Common Problems with Map Turtle Species (And How to Solve Them)
Even with the best care, issues can arise. Knowing the signs of common problems with map turtle species helps you act fast. Most issues are directly related to poor habitat or diet.
Shell and Skin Issues
Soft, smelly, or pitted spots on the shell can indicate “shell rot,” a bacterial or fungal infection. It’s usually caused by poor water quality or a basking spot that isn’t warm or dry enough. Prevention is the best cure: keep the water pristine and ensure your basking setup is perfect.
Respiratory Infections
If you see your turtle swimming lopsided, wheezing, or having bubbles come from its nose or mouth, it may have a respiratory infection. This is serious and requires a vet visit. It’s often caused by water temperatures being too low or a basking area that isn’t warm enough.
Metabolic Bone Disease (MBD)
This devastating condition is caused by a lack of UVB light and/or calcium. It leads to a soft, deformed shell and weak bones. It is 100% preventable with proper UVB lighting and a calcium-rich diet. Once advanced, it is often irreversible. This is why your lighting setup is so important.
Sustainable and Eco-Friendly Map Turtle Keeping
Part of being a great pet owner is being a responsible one. When looking for a map turtle, always seek out a captive-bred animal from a reputable breeder or rescue organization. Wild-caught turtles suffer immense stress, can bring parasites into your home, and their removal harms wild populations.
Furthermore, never release a pet turtle into the wild. It’s illegal in most places, cruel to the animal (which lacks survival skills), and can introduce diseases to local wildlife. This is one of the most important aspects of sustainable map turtle species ownership.
You can also make your setup more eco-friendly by using LED lights, putting your lights on a timer to save energy, and using siphoned tank water to water your houseplants—it’s full of great fertilizer!
Frequently Asked Questions About Map Turtle Species
How long do map turtles live?
Map turtles are a long-term commitment! With proper care, they can easily live for 20-30 years or even longer. Be prepared to be their caretaker for a significant portion of your life.
Can map turtles live with fish?
This is a tricky one. While some people have success, it’s generally not recommended. A map turtle will likely see smaller fish as an expensive snack. Larger, fast-moving fish might work for a while, but there’s always a risk of them being injured or eaten. It’s best to plan for a species-only tank.
Do map turtles bite?
Yes, they can and will bite if they feel threatened. They don’t have teeth, but their beak is strong and can deliver a painful pinch, especially from a large female. They are best considered a pet for observation rather than handling.
Why is my map turtle always hiding?
Map turtles are naturally shy, especially when new to a tank. Ensure they have plenty of hiding spots underwater (like driftwood or caves) and that their tank is in a relatively low-traffic area of your home. As they get more comfortable, they will likely become more bold.
Your Journey with Map Turtles Awaits
Bringing a map turtle into your home is an incredibly rewarding experience. Watching them swim gracefully, bask contently under their lights, and eagerly greet you for food is a joy that never gets old. They are truly living maps, each with a unique pattern and personality to discover.
The key takeaways are simple: provide a large and spotlessly clean aquatic environment, invest in high-quality heating and UVB lighting, offer a varied diet, and commit to their care for the long haul. The benefits of map turtle species keeping—from their beauty to their fascinating behaviors—far outweigh the effort.
You have the knowledge and the passion. Now you’re ready to provide an amazing home for one of these incredible reptiles. Happy turtling!
