  You have a slider, which is a semi aquatic species of turtle. Tortoises live on land exclusively. The black spots may be some algae growing or it could be early rot (infection). Maintain pristine water quality via filtration and regular partial water changes. Use a soft bristled toothbrush to gently clean the shell. If the spots persist, use a diluted Betadine or chlorhexidine (Hibiclens) solution along with the brush. Scrub once daily and allow for a 1 hour dry dock (out of the water) after each cleaning. Promote shell and overall health by providing UVB lighting, vitamin and mineral supplementation, a balanced diet and appropriate heat support.

  Biscuit may be developing shell rot. This condition is usually caused by poor lighting, poor water quality, poor diet or a combination of the three. The lack of a UVB light source may be contributing to the condition. Natural sunlight is great but the window panes can block a large portion of the beneficial UVB rays. If the shell underneath looks pitted, deformed or feels soft and spongy then there could be a serious issue. Minor shell rot can be treated at home. Use a soft bristled tooth brush and an antiseptic such as chlorhexidine or povidone to gently clean affected areas. Dry dock Biscuit until the area heals. This means keep him out of the water except for 30 minutes daily to eat, eliminate and hydrate. The dry dock (and tank) should have a UVB source placed no more than 12 - 18 inches above the tank. Use a screen instead of plexiglass or glass. Replace UVB bulbs every 6 months. Clean the tank, do a water change and change the filter media. Feed a species appropriate diet and dust food with a calcium supplement once a week or more if indicated. A cuttlebone can be placed in the tank as a source of calcium to build shell strength. Stubborn or severe cases of rot or infection should be treated by a veterinarian experienced in treating turtles. Request a consultation to discuss the case in greater detail. More detailed information and advice can be provided once the species of turtle is known.

  Shell rot can present as pitting, bleeding or redness. You may see peeling or uneven scutes and there could be an odor. The shell may also be soft. Poor water quality, nutritional deficiency and a lack of UVB lighting can all contribute or complicate the condition. See your veterinarian or a vet experienced in treating reptiles if you suspect your turtle has shell rot.
