Turtles make excellent low-maintenance pets for people of all ages. They’re quiet, fascinating to watch, and with proper care, they can be companions for decades. If you’re considering a turtle, here’s what you need to know before bringing one home.

Land Turtle or Water Turtle?

The first decision is understanding what kind of turtle you’re getting. Not all turtles are aquatic. Some species are primarily terrestrial and need dry land with occasional access to water for soaking. Others are mostly aquatic and need a large body of water with just a small dry area for basking.

Getting this wrong can seriously compromise your turtle’s health. A terrestrial turtle kept in too much water, or an aquatic turtle without enough swimming space, will become stressed and sick. Research your specific species before setting up the habitat.

Setting Up the Right Habitat

Aquatic turtles need roughly 10 gallons of swimming water per inch of shell length. A turtle with a 4-inch shell needs at minimum a 40-gallon tank. Terrestrial turtles need several square feet of floor space per inch of shell. In both cases, bigger is always better.

Every turtle habitat needs a few essentials. A basking area with a heat lamp provides the warmth turtles need to regulate their body temperature. A UVB light is critical — turtles need ultraviolet light to metabolize calcium and keep their shells healthy. Without it, they can develop metabolic bone disease, a serious and painful condition.

Water quality matters enormously for aquatic turtles. A good filtration system rated for at least twice your tank size is worth the investment, since turtles produce a lot of waste. Water should be changed regularly even with filtration.

Diet and Nutrition

What your turtle eats depends on the species. Most aquatic turtles are omnivores, eating a mix of commercial turtle pellets, leafy greens, and occasional protein like crickets, worms, or small fish. Terrestrial turtles tend to be more herbivorous, favoring dark leafy greens, vegetables, and some fruits.

Calcium supplementation is important for shell and bone health. A cuttlebone placed in the habitat gives your turtle something to nibble on for extra calcium. Avoid feeding turtles processed human food, dairy, or bread.

Temperature and Lighting

Turtles are ectothermic, meaning they rely on their environment to regulate body temperature. The basking spot should be between 85-90°F for most species, with the cooler end of the habitat around 75°F. Aquatic turtles need water temperature maintained at roughly 75-80°F with a submersible heater.

The UVB light should be on for 10-12 hours a day to simulate natural sunlight. Replace UVB bulbs every six months, as their output diminishes over time even if the bulb still appears to work.

Health and Lifespan

With proper care, many common pet turtles live 20 to 40 years, and some species can exceed 50. This is a long-term commitment that you should be prepared for before getting a turtle.

Common health issues include shell rot (from poor water quality), respiratory infections (from incorrect temperatures), and vitamin A deficiency. Regular observation of your turtle’s behavior, appetite, and shell condition will help you catch problems early. Find a reptile-experienced veterinarian before you need one.

A Few More Things to Know

Turtles can carry salmonella, so wash your hands thoroughly after handling them or cleaning their habitat. This is especially important in households with young children.

Many turtles are more interactive than people expect. They’ll learn to recognize you, come to the front of their enclosure at feeding time, and some even enjoy gentle shell rubs. They’re not cuddly pets, but they have real personality.

A well-cared-for turtle is a rewarding companion that connects you to one of nature’s most ancient and enduring creatures.
