  • Source Matters: The permit requires that your terrapin comes from a legitimate, licensed captive breeder. You will need to provide proof of this legal acquisition.
  • One is the Limit: Typically, the permit allows for the possession of only one diamondback terrapin. This is to discourage commercial breeding and ensure focus is on proper pet care.
  • No Wild Turtles: The permit does not, under any circumstances, allow you to keep a wild-caught terrapin. Even if you find one that’s injured, the proper action is to contact a licensed wildlife rehabilitator, not to keep it.

Tank Setup: More Than Just a Fish Tank

Diamondback terrapins are active swimmers and need space. Forget those small, plastic turtle kits you see in big-box stores. They are completely inadequate.

  • Size: For a single adult terrapin, you should start with a tank that is at least 75 gallons. Bigger is always better. A stock tank or a large water trough can also make a fantastic, spacious home.
  • Water Level: Fill the tank so the water is at least one-and-a-half to two times the length of your turtle’s shell. This gives them ample room to swim and dive.
  • Filtration: Terrapins are messy eaters! A powerful canister filter rated for at least twice the volume of your tank is a must-have to keep the water clean and healthy.

The Magic of Brackish Water

This is what separates terrapins from most other pet turtles. In the wild, they live in brackish water—a mix of fresh and saltwater. Replicating this is crucial for their long-term health, as it helps prevent common skin and shell infections.

To create brackish water, you’ll need marine salt (the kind used for saltwater aquariums, not table salt) and a hydrometer or refractometer to measure the salinity. Aim for a specific gravity between 1.010 and 1.018. Don’t worry, it sounds technical, but it’s easy once you get the hang of it!

Basking in the Glow: Essential Lighting and Heat

Like all reptiles, terrapins are cold-blooded and need an external source of heat to regulate their body temperature. You must provide a “basking spot” where they can get completely dry and warm up.

  • Basking Dock: Use a stable, floating turtle dock or build a platform out of slate or rock. It must be large enough for the entire turtle to climb out and dry off completely.
  • Heat Lamp: Position a heat lamp over the basking dock. The surface temperature of the dock should be around 85-90°F (29-32°C).
  • UVB Light: This is non-negotiable. Terrapins need UVB light to synthesize vitamin D3, which allows them to process calcium. Without it, they will develop serious health issues like Metabolic Bone Disease. Use a high-quality UVB bulb (like a T5 HO linear fluorescent) and replace it every 6-12 months as recommended by the manufacturer, as the UVB output degrades over time.

A Terrapin’s Menu: Nutrition and Feeding Best Practices

Providing a varied and nutritious diet is one of the most important can you own a diamondback terrapin in maryland best practices. In the wild, they eat a mix of crustaceans, mollusks, and fish.

A healthy diet for a captive terrapin should include:

  • High-Quality Pellets: Use a commercial turtle pellet specifically formulated for aquatic or carnivorous turtles as the staple of their diet.
  • Protein Sources: Offer variety with items like freeze-dried shrimp, krill, snails, and occasional pieces of fish or ghost shrimp.
  • Veggies: Some terrapins will nibble on leafy greens like romaine lettuce or dandelion greens. It’s great to offer them for variety.
  • Calcium: Always have a cuttlebone floating in the tank. They will gnaw on it as needed, which is essential for shell and bone health.

Feed adults every other day to prevent obesity, and always remove any uneaten food after about 15-20 minutes to keep the water clean.
