My pet turtle's shell is soft. Why is this happening and what to do?

Sam may not be getting enough calcium and UVB light exposure. This can lead to a soft shell. Make sure he has at least 30-60 minutes of exposure to full, unfiltered sunlight each day or provide a UVB light source in his tank. It should be no more than 12-16 inches from the surface of the basking area depending on the type of bulb. It should not be blocked by glass, plexiglass or fine mesh. The ZooMed ReptiSun bulb is an excellent light source. Feed a commercial pelleted diet and supplement with fresh greens and prey. Dust with a calcium supplement and a multivitamin. Leave a cuttlebone in the tank as a source of calcium that can be munched on when needed. It would appear there may be a vitamin A deficiency based on the swollen eyes in the image posted. Feed red or orange vegetables and dark, leafy greens as these contain higher levels of vitamin A. ZooMed Repti Turtle Eye Drops should also help. You can find it online or in most pet stores.

It would appear this turtle, not a tortoise, is suffering nutritional deficiency. Reptiles require UVB lighting, either natural unfiltered sunlight or artificially produced by an appropriate light source, in a addition to an appropriate diet with adequate calcium and vitamin supplementation. All these things will aid in the development and maintenance of a health shell. The deficiency may be reversible, however the shell may be malformed for years to come if it survives. Ideally, this turtle should be examined by a veterinarian. A specialist can be consulted via phone or online to obtain proper treatment information. In general, turtles need clean water, a heat lamp for basking, a UVA/UVB light source and a dry area for basking. Most are omnivores and will eat small prey (feeder fish, worms, crickets), fresh greens and a commercial pelleted diet. As stated above, they also require calcium and vitamin supplementation.

Since the shell is very soft, have Joan examined by your veterinarian or a vet experienced in treating reptiles. There may be an underlying metabolic issue or nutritional deficiency that may be complicating the shell infection. Review her diet to confirm adequate nutrition. Review enclosure parameters (heat, UVB lighting, etc) and correct or lower humidity levels which can predispose or be the cause of the fungal infection. If minor, the shell can be treated topically. It is not recommended to treat or medicate your pet without the advice of your veterinarian.

If there are soft areas in the shell, Ryder may have shell rot or metabolic bone disease. I would recommend a visit to a reptile vet to assess and diagnose her. Untreated these can potent be fatal. Good luck and I hope she recovers quickly. Arav.com may help you find a vet if needed.

Check the water, ambient and basking spot temperatures. Low temps can affect activity in reptiles. Ideally, the turtle should be in a 10 gallon tank. Water depth should be no more than twice the shell length. Use a filter to maintain water quality and a small heater to keep it between 82F and 85F. There should also be a basking area easily reached out of the water that should range between 85F and 88F. A UVB light source, proper diet and calcium and vitamin supplementation will promote shell health. If all this is provided and the turtle is still lethargic, consider a physical exam with your veterinarian or a vet experienced in treating reptiles. You can find one at the link below.

It is not uncommon for a turtle this small to have a somewhat soft shell. Continue to monitor for bleeding, pitting or lethargy. maintain pristine water quality. At this size, water depth should be no deeper than twice the shell length.provide a water heater, water filter, basking area out of the water, a heat lamp for basking and a UVB light source. Offer a balanced diet including prey (feeder fish, nightcrawlers, etc), fresh diced greens and vegetables and commercial pellets. A multivitamin and a calcium supplement should be dusted onto foods regularly. You can review slider care at the link below. http://www.anapsid.org/reslider.html

He should be eating some greens and vegetables as well. Avoid the fish flakes as they are high in protein. Use both a multivitamin powder and a calcium powder on the food. Rep-Cal and Zoo Med products can be found in the local Petco. Make sure the UVB light is not blocked by glass, plexiglass or fine mesh. Depending on the strength of the bulb, place the source between 12 and 18 inches from the surface of the basking area. Provide a piece of cuttlebone to float in the tank as a calcium supplement for when he wants to munch it.
