How to Tell an African Fat-Tailed Gecko's Age
Quick answer
There is no exact way to age an adult African fat-tailed gecko of unknown history — size, weight, tail condition, and reproductive development only give a rough estimate, since growth rate depends heavily on feeding history and individual genetics.
- Reliable method
- None — estimate only
- Best indicators
- Size, weight, maturity signs
Why exact aging isn't possible
Unlike a tree ring or a bone growth line you can count, an African fat-tailed gecko's outward size is shaped by diet and rearing conditions as much as by time, so two animals hatched the same week can look years apart in size by adulthood.
What keepers actually use
Adult length and weight, whether the tail looks original or regrown, skin and colour condition, and — in adults — sexual maturity markers together narrow an estimate to a broad range rather than a specific year.
