How to Weigh a Crested Gecko?

I do not think it will be difficult for you to do such a procedure. You should take the usual scales to measure in grams. I even utilize regular kitchen scales. So, take a container, a box, or even a mug. Put a tall container on it and bring the weight down to zero. Then you have to put your lizard in the container and weigh it. If you use a mug, then put the gecko upside down.

Why Is My Crested Gecko Not Growing?

Think about a few factors that can affect the adult crested gecko weight or growth of your pet. It may be:

  • Malnutrition. Please pay attention to your pet’s appetite and possibly change its diet.
  • Too much moisture or cold can adversely affect its growth and development.
  • Little or a lot of light.
  • Large or small terrarium.
  • Vermin, etc.

How to Tell If a Gecko Is a Boy or Girl?

You may want to buy a newborn male or female reptile of this species. However, I will disappoint you. These lizards have such a feature that you won’t determine the sex before 3-5 months. Already at this age, you should touch the gecko in the area of the tail (at its base). So, if you feel two bulges, it is a male. You won’t find them in females.



Have you decided to buy a gecko, or have you already done so? Then review all the necessary care information. After all, many factors and different conditions affect its development. How to tell how old a crested gecko is? You can look at its skin color. The older lizard has a dull color. Each individual has its characteristics, but still, the size and weight will help determine the age.
