Croc skinks are not big on being handled. When held, they will usually be stiff and quiet in your hand–which usually means they’re not very happy and are just waiting for their chance to bolt back to safety. You can hold them some, but frequent handling is not recommended. If you provide the correct environment they can be quite active, even coming out some during the daylight hours (especially if you feed at around the same time every day).
Red eyed croc skinks come from moist, cool places in New Guinea. They are not huge climbers but will climb low lying branches and decor. Floor space is more important than height in your skink’s enclosure. Croc skinks do best when kept singly or in pairs of a one male and one female. Males kept together will fight. Females kept together become defensive and territorial.
Croc skinks prefer a very high humidity level. Providing lots of hiding spots, low lying foliage cover, and some taller foliage will enable your skinks to feel comfortable coming out. They like it if there is always a safe place close by to duck into.
