Map Turtle Tank Size?

Question

would a 20 gallon tank be sufficient for a full grown male map turtle?

Answer 1

A 20-gallon tank should be fine. Don't get too detailed about what the EXACT MEASUREMENTS of a tank should be. If he has room to swim around, then that's perfect. The turtle is not gonna pull out his measuring tape and measure it. If you're curious anyways, here is what the internet says:


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 ENCLOSURE

Recommended size for a single adult Graptemys pseudogeographica pseudogeographica would be a 30 gallon aquarium as a minimum (40 or larger preferred) for males, and a 75 gallon aquarium as a minimum (90 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 pseudogeographica pseudogeographica, I would recommend adding 20 gallons of tank space for additional males and 50 gallons of tank space per additional female at a minimum.

Stock Tanks and Rubbermaid containers also work well. The same space recommendations remain the same.

Answer 2

Since they get to be 3-5 inches long, and the rule of thumb is 10 gallon per inch of shell, you need a minimum of 30 gallons, and maybe larger.
