Why is my crested gecko sluggish, twitching, and looking up?

Anytime a reptile becomes excessively lethargic, you must check the ambient and basking temperatures. Low temps can dramatically affect activity and appetite. Set daytime temps between 78 F and 82 F . Night temps can drop into the low 70s F. A small basking area set at around 80 F should be provided. They are nocturnal, so don't expect a lot of daytime activity. Offer a variety of appropriately sized prey (crickets, dubia roaches, etc.) as well as a commercial gecko diet. You may need to hold prey in front of him or tap his nose to elicit a strike. Do not attempt to force feed him. Soak him in a warm 50/50 solution of water and unflavored PediaLyte. Gently stroking his abdomen during the soak may produce a bowel movement if he hasn't been defecating. The soak will treat or prevent mild dehydration. If he continues to exhibit this behavior or does not start eating, have him examined by an experienced herp veterinarian. Submit a stool sample to diagnose intestinal parasites.

Those temperatures are much too cold for a crested gecko. Ideally, daytime temps should range between 78F and 85F with nighttime Temps no lower than the low 70s F. Low temps can affect appetite and activity in reptiles. Some form of prey is necessary as a protein source in addition to the fruit and vegetable mixes.

This is all normal behavior an no cause for concern. Cresties will lick their eyes and noses frequently. Her slow walk is likely her just being cautious. Move slowly and talk softly when you are around her cage.

She may be a bit cautious and apprehensive in her new environment. Give her a few days to acclimate. Confirm proper environmental parameters, especially heat /temperature. Low temps can affect activity in reptiles. make sure the lighting is not too bright also.

Hello. While 75-80F is a good range for the warm end of the cage, it would be ideal to have temps from 68-75 at the cooler end so he can self regulate his temperature. If the enclosure is too small to allow such a temperature gradient, then you may find your gecko will become stressed from being either too hot or too cold, and then susceptible to infection. Look through the enclosure and over his body for signs of infection or illness. Count food items offered so you can be sure how much he eats. Also consider a red or blue bulb for night viewing. This may help you observe his nocturnal activity better. Regardless, a new pet exam by a veterinarian is always a good idea to ensure good health and proper husbandry. Good luck!

Warm him up. Check your tank temps (ambient and basking). Low temps will affect activity and appetite. Use a timer to set a 12 hour light cycle. An infrared heat bulb can be used at night if room temp goes below 70F. See an experienced herp vet for an exam to diagnose illness or injury if symptoms persist.

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/
