What is the Crested Gecko Species Identifier?
The Crested Gecko Species Identifier identifies likely species or morph of crested geckos from pattern and color cues. Knowing what you're working with shapes everything from diet and housing to expected size and temperament. That is useful for new owners and shelters alike.
A well-cared-for crested gecko usually lives somewhere between 15 and 20 years. Diet-wise they are a frugivore, which shapes almost every feeding decision you make. Crested geckos are arboreal and need a tall planted enclosure rather than a wide one, kept at room temperature between 22-26C. They thrive on prepared powdered diets and cannot tolerate heat above 28C. Keep an eye out for metabolic bone disease, floppy tail syndrome, heat stress above 28C. These are the conditions crested geckos are most commonly seen for.

How does the Crested Gecko Species Identifier work?
The result is based on matching the traits you describe against commonly documented characteristics for crested geckos, not genetic testing. Individual crested geckos vary more than averages suggest, so read the number as a reference point rather than a measurement.
Factors that matter
- Physical traits such as size: coloring and markings
- Behavioral traits: which can be just as informative as appearance for some questions
- Age: since juvenile traits can differ noticeably from adult ones
- Photo or description quality: the more specific your input, the more useful the match
How do you use the Crested Gecko Species Identifier?
- Pick your adult size (Very small, Small, Medium, ...)
- Pick your coat length (Hairless or very short, Short and dense, Medium, ...)
- Pick your ear carriage (Erect, Folded or dropped, Semi-erect, ...)
- Pick your overall build (Slender and fine-boned, Balanced, Stocky and heavy-boned)
- Pick your dominant color pattern (Solid single color, Two-tone or bicolour, Brindle, merle, tabby or ticked, ...)
- Press Calculate, then read the result alongside the sources listed below
One practical habit: revisit this every few months rather than checking once. Crested geckos change as they age, and the right answer changes with them.

Before you rely on this
One number on one day is rarely the full picture. What matters more is the direction of travel: whether your crested gecko is trending steadily, drifting, or changing suddenly. A sudden change is always worth a call to your vet, even when the individual figure still falls inside a normal range.
