[header] How to keep a turtle healthy [title] Provide an enclosure with adequate space. [step] Ten gallons per inch of your turtle is a general rule. 50 gallon (189.3 l) minimum for a baby turtle (younger than a year old) and 120 + for an adult. <sep> (A) Make sure that you have a general idea of the size your turtle will reach when full grown so you are not blindsided with keeping a turtle you cannot maintain. [substeps] Decide on a land or aquatic turtle. (B) If you pet a turtle too many times, it can run away. A turtle needs something to run on, such as leaves, instead of sand or gravel, and a tank that fits tightly. (C) This will give you time to adjust to the turtle's size and health while still allowing the turtle to bond with the family. [substeps] A turtle's enclosure should be 6.8 inches (23 cm) by 12 inches (30 cm). (D) Turtles of any species should have an enclosure at least 20 feet (4.5 m) wide by 50 feet (6.1 m) deep. It's best to provide a tank that is similar to the size of your turtle.
