They have broad heads and strong jaws that enable them to crunch the shells of mollusks and bones of the carrion, from which they feed. The Black Marsh Terrapin can be found in Southeastern Asia. They are most common in Sumatra, Thailand, Borneo, Malaysia and Java. Uncertain Captive Black Marsh Terrapins are happiest when fed on a diet resembling that in the wild, consisting of worms, snails and other live, aquatic animals. They can also be fed commercial, floating turtle food or cat or dog food, provided it is supplemented with live food.
Juveniles can feed on bloodworms and commercial food that has been crushed.
For a single turtle, a 20-gallon aquarium is usually sufficient. The water should be kept between 78 and 82 degrees Fahrenheit, or 25 to 28 degrees Celsius. The water should be moderately shallow, with hiding places for the turtle. There should also be a dry area with a basking light. The basking light should heat one area of the aquarium to about 85 degrees.
