My crested gecko's tail looks kinky. Is it MBD or floppy tail?

Overall, she looks quite thin. The kinks in the tail may be an early indication of metabolic bone disease (MBD). 21 C is a bit cool for her. Cresties do best between 25.5 C and 27.7 C Ideally, she should be evaluated by your veterinarian to confirm and treat MBD or other illness/infection. Submit a stool sample to diagnose intestinal parasites. IN the meantime, you can review care at the link below. http://www.reptilesmagazine.com/Care-Sheets/Lizards/Crested-Gecko/

Yes possibly these are signs of MBD. Ideally a check up is required to diagnose (an x ray may be needed) and treat it appropriately.

This could be an injury or very early MBD (metabolic bone disease). Have Harper examined by your veterinarian or an experienced herp vet for confirmation. Review her diet and vitamin/mineral supplementation regimen. If it is MBD, it can be corrected with just a few tweaks in diet and lighting. Check the age of the UVB bulb. If it is older than 6 months, replace it with a new bulb. You can review care and feeding of bearded dragons at the link below. http://www.anapsid.org/bearded.html

Thanks for reaching out about the chameleon and including pictures. The first photo with the swayed back is very suspect of MBD/calcium deficiency. Diet and husbandry need to be review and correct, and a veterinary visit should be scheduled ASAP. Typically concerns are poor calcium in the diet, lac of UV light, poor temperature, etc. This is an emergency. Good luck.

Thanks for reaching out about Stretch tongue and including photos. First thoughts are this is a male and impacted hemipenes. Second thought is calcium deficiency and coccygeal (tail) vertebral luxation. Check and correct husbandry and diet, but an examination with someone with reptile experience is recommended. Good luck.

Thanks for reaching out about your gecko and including photos. This animal is emaciated and starving for nutrients. A veterinary visit if highly recommended, ASAP, as it appears severely ill. Intestinal infections/parasite and metabolic disorders (liver, kidney) are among the most common causes. Check and correct husbandry as environmental parameters (heat, UVB exposure, humidity) are extremely important for recovery. Offer water and food through a syringe until a veterinary appointment can be made. Good luck.

MBD can be treated, but Dobbie may never be "normal". Ideally, he should be physically examined by your veterinarian or a vet experienced in treating reptiles. If he has MBD, he likely has other issues related to poor husbandry and nutrition. Submit a stool sample to diagnose intestinal parasites. He may need antibiotics to help with the wound on his face. There maybe nothing to be done with the tail other than partial amputation if it is causing discomfort. Your vet can determine this after an exam. With the proper care and support, he can lead a close to normal life. You can review water dragon care at the link below.
