Roux’s giant gecko or slender prehensile-tailed gecko is better known from its Latin name Correlophus sarasinorum (previously in the genus Rhacodactylus). C. sarasinorum is an arboreal and nocturnal gecko and is bigger than the crested gecko (adult SVL about 13 cm).
This slender gecko has a smooth velvet-like skin. There are several color morphs for this species. The « patternless » geckos have by definition a rather uniform color, from brown-red, brow-yellow to dark brown. The « mottled » individuals have a marbled pattern made of two shades of color (we do not have this morph in our breeders). Finally, our favorite is the « white-spotted » morph that consists of large white spots on the back of the animal.
Our animal that have these white spots also have a « white-collared« , a band linking both eyes and forming a characteristic V. They also have white marks on their tail.
C. sarasinorum loves to climb. Thus, the terrarium must contain some branches. We recommend a terrarium of minimum 50x50x70cm (LxPxH) for one male with 2 or 3 females. Similarly than for the other geckos living in humid environments, we advise to have a natural substrate and green plants.
During summer, the terrarium should reach a temperature of 24-26°C during the day and be a bit cooler during the night. During winter, the temperature will be slightly colder, about 22-24°C.
C. correlophus is not complicated to feed. It appreciates the Repashy, powder, mashed fruits or baby mashes and insects like crickets.
Similarly to the crested and gargoyle geckos, the sex of the juveniles cannot be determined. When males reach a SVL size of a bout 8 cm, the bulges that contain the hemipenis will become visible, as well as the spurs that are present at both sides of the cloaca. It is also possible to observe the preanal pores using a lens. Males have two rows of pores.
The reproduction of this species is more hazardous than for the crested and gargoyle gecko. Indeed, while some females can lay up to 6 clutches of 2 eggs per breeding season, others might not produce any egg during a season or two…
