Quebec and NW Vermont west to Wisconsin, south to Arkansas and Georgia. Can also
be found in Pennsylvania, Maryland and the Delware River.
These are aggressive baskers, so a
basking spot is required. UVB lighting is needed as well as a heat lamp over the
basking spot. A submersible heater is recommended if the water temps fall below
the recommendation. They are excellent swimmers and their captive habitat should
have a water depth as deep as possible. Substrate should be anywhere from a sand
to a fine-to-medium size gravel.
Recommended size for a single adult
Graptemys geographica would be a 40 gallon aquarium as a minimum (55 or
larger preferred) for males, and a 90 gallon aquarium as a minimum (100 or
larger preferred) for females. This will provide adequate swimming area, as well
as assisting the filtration in maintaining good water quality. For additional
Graptemys geographica, I would recommend adding 20 gallons of tank space for
additional males and 40 gallons of tank space per additional female at a
Stock Tanks and Rubbermaid containers
also work well. The same space recommendations remain the same.
In captivity, they do well on
Mazuri and ReptoMin, Reptile/Pond 10, Cichlid Sticks, some aquatic

Common Map Turtles are a great turtle
for a community habitat with Mud Turtles, Musk Turtles, Sliders, Cooters, other
Map Turtles and Painted Turtles.
Common Map Turtles are not quite as skittish as are other species
of map turtles, but they do retain some of the typical map turtle nervousness.
Map turtles in general are sensitive to
water quality, so close attention to their water quality is needed.
