Snake-Necks are mostly carnivorous and will forage for food during the day. In captivity they tend to be less interested in pelleted foods but they thrive on a varied diet of small fish, crustaceans, vitamin-supplemented meat (e.g. non-fatty chicken, ox heart ), fresh frozen aquatic turtle food, tinned dog food, mice pups, soaked cat biscuits, insects, insect larvae, snails, worms, fish flakes, trout pellets and reptile pellets.
A good basking area must be easily accessible to the turtle but it must also be completely dry and warm. A turtle that is not seen basking for several hours every day is likely to be having problems accessing the basking area, or the temperature difference between the water and the basking area may not be ideal, and this can result in long term health problems such as weakened bones and a softened shell. The basking area must also have twelve hours of UVA and UVB light and a heat source that will encourage the turtle to remain in the basking area (the basking area should be at least 6 degrees warmer than the water temperature so do not let the water get too warm).
