Hi, I've been weighing and measuring my juvenile AFT since a little over a month ago. Since April 23rd she has not grown at all. She's 22g and 6 inches (short because her tail is regenerated). I'm not sure how old she is but she is definitely under a year. Is this normal?
At that size and age, growth should be noticeable. However, five weeks is a relatively short period of time. There are two obvious causes that come to mind- insufficient feeding, or parasites. Parasites are uncommon in captive bred geckos, but in wild caught geckos, they are a given. If your gecko is wild caught, have your vet run a fecal.
If your gecko is captive bred, try feeding it more frequently.
