Chinese water dragon (green lizard) Physignathus cocincinus. Males can grow up to 36 inches in length, females up to 24 inches. Its color can vary between a bright green and a dark brown, according to the stresses of its environment.They are native to Southeast Asia. They swim well, and can submerge themselves for long periods of time, up to 30 minutes. They are capable of eating insects, small fish such as goldfish, small mammals such as "pinky" mice, and certain vegetation. The dragon typically will drop from a branch into a body of water when startled. It has been known to occasionally escape predators on land by raising up and running on its hind legs.

General Info:
Adult length up to 40".
Water dragons can be long-lived pets if maintained properly. These water loving animals do best in large terrariums and benefit from the use of air stones in their water bowls. If possible, small water features should be included within water dragon enclosures to simulate the moving water they are accustomed to in their native habitat.
Temperature/Humidity:
Ideal daytime temperature for water dragons should range between 75 and 85 degrees. Additionally, a basking lamp should be used to maintain a local temperature of 90 to 95 degrees. Nighttime temperature should remain between 65 and 75 degrees. The humidity for these lizards should be kept at or near 70 percent.
Lighting:
Chinese water dragons require ultraviolet lighting to maintain good health. Ultraviolet lighting is recommended for 12 hours per day. The use of a timer will help maintain an accurate lighting schedule.
Feeding/Watering:
Water dragons are omnivorous (eat both animal and plant matter). Therefore their diet should include insects, vegetables, fruit, and prepared foods (such as pelleted dragon food). Insects such as crickets, mealworms, superworms, and waxworms will be consumed with gusto. Other suggested foods to feed once a week: dark, leafy greens (mustard, collard, radish, and turnip greens or tops, kale, cabbage, dandelion leaves-stems-flowers, broccoli, non-treated backyard grasses and weeds, clover), legumes, mulberry and grape leaves, roses, hibiscus, nasturtiums, carnation flowers, cured alfalfa and timothy hay, soaked alfalfa pellets, thawed frozen mixed vegetables (peas, lima beans, carrots, green beans), peas in the pod, cauliflower, soy bean sprouts, radishes, summer and winter squashes, grapes, apples, oranges, pear, peaches, plums, nectarines, dates, all types of melons, strawberries, raspberries, bananas, mangoes, and tomatoes. Some high protein content foods suggested are: dry maintenance dog food, tofu, and scrambled or hard-boiled eggs. When feeding fruits & vegetables, use four vegetables to every fruit per meal. It may be best to only offer fruits in every third or fourth feeding. Red fruits are great for shy eaters as reptiles are naturally attracted to the color red. Feeding every other day is suggested as well as dusting food with vitamin/calcium powder every other feeding. Always remove food four hours after it is offered to prevent spoilage. Offer insects every 3-4 days as supplement to the vegetation offered. An easily accessible deep water dish works best with dragons. Water should be changed daily.
