Rough Green Snake Facts

Average Adult Size 2 ½ to 3 feet
Average Life Span up to 15+ years with proper care, depending on species
Diet insectivore

Will reach adult size in 2 to 3 years, under ideal conditions; upgrade habitat size as your snake grows.


A well-balanced rough green snake diet consists of:

  • Gut-loaded (recently fed) crickets, mealworms or superworms, as rough green snakes are one of the few insectivore snakes.


Things to remember when feeding your rough green snake:

  • Feed once or twice a week.
  • Sprinkle food with calcium supplement daily and a multi-vitamin supplement once or twice a week.
  • Fresh, clean, chlorine-free water should be available at all times in a large enough bowl for your snake to soak in.


  • Size - Appropriately sized and shaped habitat for an adult rough green snake to accommodate normal behavior and exercise, at least a 20L tank.
  • Substrate - Mulch type, coconut fiber bedding, dampened sphagnum moss and reptile bark.
  • Habitat - Provide a hiding area just large enough for your snake to fit inside and a branch or décor to climb on. Maintain 40 to 60% humidity; higher during shedding.
  • Temperature - Temperature gradient (80°F for the warm end and 70°F for the cool end).
  • Provide a basking area about 85 to 88°F to aid digestion.
  • Lighting - Snakes need a photo period light cycle; provide 8 to 12 hours of light daily. Don't leave white light on at all times; a black or infrared light should be used at night.
  • Do not house different snake species together.

Normal Behavior

  • As snake gets ready to shed, eyes will turn a milky blue/grey over the course of a few days and body color will start to dull and develop a whitish sheen. May become irritable, so avoid handling. Appetite may vary.

Habitat Maintenance

  • Thoroughly clean and disinfect the habitat at least once a week: place snake in a secure habitat; scrub the tank and furnishings with a 3% bleach solution; rinse thoroughly with water, removing all traces of bleach smell; dry the tank and furnishings completely and add clean substrate.

Grooming & Hygiene

  • Snakes will regularly shed their skin; ensure humidity of habitat is at appropriate level to allow snake to shed properly.
