are amazing animals that are very similar and easy to take care of. They are crepuscular (active day/night) although mine tend to be more active at night. They require room temps not to exceed 82 degrees so keep that in mine if you can not control your temps. They eat a powder mixed with water, and enjoy live feeding of roaches or crickets (not required ). They love to climb and prefer height to width, so keep that in mind when purchasing an enclosure.
They love places to hide so they will need vines, plants (fake or real), and hides. They are naturally skittish creatures and its not that they don’t trust you, but they may run away from you when held. Every gecko has its own tolerance levels. Do know that if their tails drop, which they do as a defense mechanism, it will not grow back. Do know that females may lay duds at around 20g, even if not paired. Males may become “ sexually aggressive” as early as 15g, biting at your hands (they latch on to females this way). Most will not break the skin and not all males do this, but I know this can be a deal breaker for many people down the line.
Geckos not feed a complete crested gecko diet may develop metabolic bone disorder so its very important that you buy the right food for your gecko. Calcium may be offered but it generally not needed. You can offer a little powder or buy liquid calcium paying great attention to the proper dosage. Sometimes they can get parasite overload if they get sick or are exposed to another gecko with worms. After determining what parasite it is, you can easily treat it. Signs that a gecko may have parasites is a very skinny and lanky gecko that has dramatically lost weight. You may visually see worms in their feces if the infestation is that bad, but normally eggs are passed in the feces that are not spotted by the eye. This is why quarantining is so important. Crested and Gargoyle geckos live a long time, 20+ years so keep that in mind before purchasing.
A fertile egg when under a light will have a red ring. This ring will be redder and bigger the older the egg is. A non fertile egg will just show up as completely yellow. Sometimes it won’t show rings but instead dark dots or marks, or if its been freshly laid the ring won’t be as pronounced. When in doubt, incubate.
