TURTLE & TORTOISE CARE GUIDES

Long-lived. Often surrendered. Almost always misunderstood.

Turtles and tortoises are some of the most-mismatched pet reptiles in the United States. Sulcatas grow into 80+ pound adults. Red-eared sliders need 75-gallon-plus tanks they almost never get. Russian tortoises live 40+ years. We cover the actual commitments — not the marketing version.

russian tortoise

INTERMEDIATE · LONGEST-LIVED

Russian Tortoise

The most commonly kept tortoise in the US. Small enough to manage. Long enough lived to outlast its first owner. Active enough to need real space — not the cramped table most are kept on.

sulcata tortoise

ADVANCED · GROWS TO 100+ POUNDS

Sulcata Tortoise

The #1 surrendered reptile in the United States. The hatchling is the size of a hockey puck. The adult is the size of a large beanbag. Most people who buy them are not ready.

red eared slider

AQUATIC · MOST-MISSOLD TURTLE

Red-Eared Slider

The classic "carnival turtle." The little 50-cent hatchling becomes a 12-inch adult that needs a 75-100+ gallon tank with strong filtration, basking platform, and UVB. Most owners discover this too late.

TERRESTRIAL · NATIVE NORTH AMERICAN

Eastern Box Turtle

Native to the eastern US. Outdoor housing strongly preferred. Long-lived omnivore that has been devastated by wild collection — only buy from captive-bred sources.

Before you choose a turtle or tortoise

Read the species guide all the way through, including the "adult size and commitment" section. Then ask yourself two questions:

  • Can I provide adult housing? For sulcatas, that's a heated outdoor enclosure in a warm climate or a substantial indoor space in a cold one. For red-eared sliders, a 75-gallon-plus tank with filtration. Don't buy what you can't ultimately house.
  • Will I still be here in 30-50 years? Russian tortoises live 40+. Sulcatas can hit 80+. Red-eared sliders can live 30. This animal may outlive you. Have a succession plan.

If either answer is no, the responsible move is to pick a different reptile. Plenty of species fit better with most lifestyles.
