Rough green snake
Opheodrys aestivus · also called Rough greensnake, Grass snake, Green grass snake, Vine snake (regional)
A delicate, brilliant-green arboreal colubrid native to the eastern and south-central U.S. that is unusual among pet snakes for being a dedicated insectivore. It is a beautiful but demanding 'look, don't touch' species that stresses easily, and captive-bred animals should always be chosen over wild-caught.

Part of the Colubrid snakes
Colubrids are the largest and most diverse snake family, encompassing most popular non-constricting and mildly constricting pet snakes. They range from hardy beginner species to specialized insectivores, and are generally non-venomous and manageable in captivity.
Habitat & space requirements
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.
Habitat & enclosure
Strongly arboreal and best housed in a tall, well-planted bioactive terrarium. A single adult needs an absolute minimum of 18"L x 18"W x 24"H, with 18"x18"x36" or larger strongly preferred to allow full vertical climbing and stretching. Provide a dense network of thin climbing branches, vines, and live or artificial foliage so the snake can hide among leaves at multiple heights. Maintain an ambient gradient of about 75-82F (24-28C) with a warm basking zone around 85F (29C) and a nighttime drop into the low 70s. Keep humidity around 50-70% with daily misting; these snakes often drink water droplets from foliage rather than a bowl. Provide low-output UVB (e.g., 5-7%/T5 at appropriate distance) as a diurnal, sun-basking species.
Substrate
Use a moisture-retentive substrate such as coconut husk fiber, cypress mulch, orchid bark, or a sphagnum-topped bioactive soil mix that supports live plants and holds humidity without becoming waterlogged. A bioactive setup with a cleanup crew (springtails, isopods) and live pothos, ficus, or similar foliage suits this species exceptionally well and helps maintain humidity and air quality.
Equipment & setup
Tall screen-topped or front-opening terrarium; low-wattage overhead heat source on a thermostat for the basking zone; low-output UVB lamp; digital thermometer/hygrometer; fine misting system or hand mister (automated misting is ideal); abundant thin branches, cork, and live/silk plants for cover; shallow water dish plus mist droplets for drinking.
Diet
An obligate insectivore, one of the very few commonly kept snakes that does not eat rodents. Feed a varied diet of appropriately sized soft-bodied insects: gut-loaded crickets, small grasshoppers, moths, spiders, soft caterpillars (avoid toxic/hairy species), and the occasional gut-loaded roach. Prey should be roughly the size of the snake's head. Juveniles eat daily or near-daily; adults take 2-4 prey items 2-3 times per week. Dust feeders with calcium and a reptile multivitamin to prevent metabolic bone disease. Many wild-caught individuals refuse food in captivity, which is a major reason captive-bred stock is preferred.
Behavior & temperament
Diurnal, extremely active, and visually oriented, foraging through foliage by day. Non-venomous and not inclined to bite people, but they are exceptionally shy, fast, and prone to chronic stress. They tolerate handling poorly and may musk, thrash, or go off feed; they are best treated as a display species observed rather than handled. Wild-caught animals frequently fail to thrive, so this species is recommended only for keepers prepared to meet exacting husbandry needs.
Health
Common problems trace back to stress, dehydration, and an insect-only diet: metabolic bone disease from poor calcium/UVB, dehydration and poor shedding from low humidity, internal parasites (very common in wild-caught animals), and stress-driven anorexia. Provide UVB, dust insects, keep humidity up, and minimize disturbance. Quarantine new arrivals and have a fecal parasite check done. Persistent food refusal, weight loss, or sunken eyes warrant prompt exotic-vet attention.
Tips, DIY & hacks
Always buy captive-bred animals; wild-caught rough green snakes have very high failure rates. Plant the enclosure densely, the snake hides in foliage and feels secure when greenery is thick. Mist in the morning so the snake can drink droplets. Vary the insect menu and gut-load/dust every feeder. Resist handling; success with this species is measured in years of a calm, feeding, display animal rather than a 'pet you hold.'
