Red-eyed crocodile skinks reach 7 to 10 inches with distinctive keeled, armoured scales. Their small size keeps the footprint modest, but a shy species needs the enclosure densely furnished.

Getting there

Small and quickly finished

They reach adult size early and the housing requirement does not change substantially.

The red eye-ring develops with maturity

It is the feature the species is named for and becomes more pronounced in adults.

What that size means in practice

A small, humid, heavily furnished enclosure

Their size keeps the footprint modest, but they need leaf litter, cover and a water area. Cover is what makes a shy species settle.

Males should be housed separately

They are territorial toward each other, and conflict in a small enclosure is serious.

Common questions

How big do red-eyed crocodile skinks get?

Adults reach 7 to 10 inches, with males slightly larger than females. They have distinctive keeled, armoured-looking scales.

How big an enclosure do red-eyed crocodile skinks need?

Modest in footprint but densely furnished, with leaf litter, cover and a water area. Cover is what allows a naturally shy species to settle and be seen.

Can red-eyed crocodile skinks be kept together?

Not two males, which are territorial toward each other. A male with a female is the usual arrangement where they are kept in pairs.
