Factors Causing Color Change of Crested Gecko

There are three ways that can cause your gecko to change its color, and they are listed below.

  • Age-related color change
  • Environmental color change
  • Color change due to shedding
Age-related Color Change

You would have already known the adult color of your gecko around its first anniversary.

The adult color can be different from its hatchling or juvenile color. Another thing is that the patterns of crested geckos are also age-related, just like color.

You will find little or no marks and spots on hatchlings, but it will start to show once it grows older.

Environmental Color Change

Adult geckos can still change their color through a process known as firing up. This process of firing up and down of a crested gecko is based on numerous factors. However, some of the environmental conditions that can cause firing up of your gecko are stated below.

The mood of your gecko due to its environment: Moods like stress, aggression, and fear can lead to your crested gecko firing up. These moods like stress and fear reactions of your gecko can be caused by shipping, new environment, overpopulation, bad living conditions, handling, or breeding.

High temperature: If crested geckos are kept in an enclosure with a temperature of about 80 degrees Fahrenheit, it will fire up. However, you should avoid exposing them to high temperatures (over 85 degrees Fahrenheit) for a long time, which can lead to overheating.

High humidity: If your geckos are kept in an enclosure of higher humidity of about 70%, it can fire up. High humidity levels usually occur at night or in the morning.

Activities of your gecko: Crested geckos have fired down colors when they are sleeping while the color fires up when they are active.

It is also possible that it is exposed to fear or stress during this period.
