Diamondback Terrapin’s Checklist (Things Needed for Habitat Setup)

Diamondback Terrapin’s are amazing creatures but they are not beginner-friendly pets as they require a specific care that is different from other aquatics. However, a lot of people still keep them as pets because of their beauty and personalities.

Diamondback Terrapin’s are native to North America, found along the eastern Atlantic coasts and the Gulf coasts. Unlike other aquatics, these turtles prefer Brackish water (between salt and fresh water). So, in captivity, you will need to mimic this type of environment as much as possible.

In order to properly care for your turtle, you will need a number of tools and supplies.

List of supplies needed for Diamondback Terrapin’s


Diamondback Terrapin’s do grow fairly large. A female can get to 9” depending on the specie you have. That’s why you will need a larger tank. For a female, a 75 gallon is recommended while 55 gallon is enough for male as they are comparatively smaller than the females.

List of things you willl need inside the aquarium.


Like all other turtles Diamondback Terrapin’s too need a water filtration system that keeps the water clean and smell free. We recommend buying a quality water filter for your turtle that will run for long periods of time.

Water Heater

Ideal water temperature for these turtles is between 70 to 78 ºF. You might need a water heater installed in the aquarium to achieve this. Purpose made water heaters for turtles are available in most of the pet stores online and offline.


To keep the temperature of water under desired level you will need a thermometer installed inside your turtle terrarium. Due to the fact that the basking Area temperature is different you will need two thermometers. Basking area temperature should be between: high 80’s, very low 90’s.

UVB Light

UVB plays an important role in the health of Diamondback Terrapin’s turtles. Without proper UVB light your turtle can get sick. That’s why you will need a UVB bulb installed in the aquarium somewhere accessible.
