Updated On September 23rd, 2025

my turtles shell is peeling and i’m a little worried something is wrong. she also has white spots down the center of her shell. i have tried to feed her veggies but they just float around in her tank for a while. is there a way i could get her to eat more than the pellets i give her? she doesn’t have sun in her tank but she does have a heat lamp, is that enough for her to stay healthy? i’m just don’t want her to die so i have a lot of questions sorry

Turtles need more than a heat lamp for good health. Basic requirements include: clean water, a water heater, UVB light, basking platform, balanced diet and vitamins and minerals. Sunlight is good, however window panes and tank glass block most of the beneficial UVA/UVB rays that turtles need to synthesize Vitamin D3 and to properly utilize calcium. A good UVB bulb should be placed above the tank no more than 12-14 inches away from the basking area. It should not be blocked by glass, Plexiglass or fine mesh. The peeling and white spots may be due to poor water quality, poor diet, lack of UVB lighting or a combination of the three. Keep water clean via filtration and weekly partial water changes. Scoop out uneaten food daily. The filter should be rated for at least twice the volume of the tank since turtles can be very messy. You may be able to get Shelby to eat greens if you offer them about an hour or two after the heat lamp comes on in the morning. This will give her time to warm up. A cold reptile will not eat. Dice the greens and vegetables into manageable pieces. they should be dusted several times weekly with a calcium supplement and a multivitamin. Once she eats the greens, you can offer pellets and protein (feeder fish, nightcrawlers, crickets, raw beef heart, etc.). The spots can be gently scrubbed daily using a soft bristled brush and diluted Betadine or chlorhexidine (Hibiclens). Allow for a 1-2 hour dry dock (out of the water) after each cleaning.If it doesn't improve or if Shelby becomes lethargic or stops eating, then have her examined by a your veterinarian or a vet experienced in treating reptiles. Since most aquatic turtles are red eared sliders or yellow bellied sliders, I have included a link regarding care and keeping below. If you have a different species, post a new question with the species or request a consultation and we can discuss the case in greater detail. http://www.anapsid.org/reslider.html
