Blue Tailed Skink Enclosure: Temporary Care and Setup

A blue tailed skink enclosure has to solve two problems at once. The animal is often a wild juvenile someone found in a yard. It is not one species, but a shared color stage across several native North American skinks.

Setting one up starts with a legal and welfare question. It then moves to housing for a small, secretive lizard from moist woodland, not desert.

The sections below cover a short term holding container first. Then comes a full blue tailed skink enclosure, with size, substrate, temperature, and lighting numbers for each stage.

Found a Blue Tailed Skink? Decide Release or Keep First

“Blue tailed skink” is not a species name. It is the juvenile pattern shared by several native Plestiodon lizards.

The most common are the five lined skink, the broadhead skink, and the southeastern five lined skink. The western skink shares the pattern too, farther west.

All of them hatch with light stripes on a dark body. All show a bright blue tail. For range and identification detail, see the blue tailed skink overview and the five lined skink page for the adult stage.

These are wild native lizards. Collection rules vary by state. Some states list native skinks as protected.

Connecticut, for example, lists the five lined skink as state threatened. Its wildlife agency advises leaving any wild skink alone rather than capturing it.

Other states allow limited collection under a hunting license. Some allow none without a scientific permit. Check your own state wildlife agency before building any blue tailed skink enclosure.

If keeping the animal is not legal, release it. The same applies if it is an adult female likely tending eggs nearby. Release it exactly where it was found.

Never release a pet store or previously captive lizard into the wild afterward. It can carry disease into native populations. If collection is legal and you intend to keep the skink, move on to setup.

Short Term Holding While You Decide

A skink does not need a finished enclosure in its first hours with you. A ventilated plastic tub of 1 to 5 gallons works as a holding container. Line it with damp paper towel.

Add a shallow water cap. Tuck in a folded paper hide so the animal is not exposed. Keep the tub at room temperature, roughly 70 to 75 degrees Fahrenheit.

Keep it out of direct sun. A sealed container can overheat fast in sunlight. This setup should last hours to a couple of days, not weeks.

Use that window to confirm legality. Identify the species by range and pattern; the size guide covers adult and hatchling measurements by species. A roughly handled juvenile may drop its tail in defense, and the bite and handling page explains why.

Blue Tailed Skink Tank Size

General veterinary housing guidance for small terrestrial lizards calls for roughly 0.2 square meters, about 2.15 square feet, of floor space for every 10 centimeters of body length. A hatchling skink measures 5 to 6.4 centimeters and needs little floor area. It can start in a 5 to 10 gallon enclosure.

An adult five lined or southeastern five lined skink runs 5 to 8.5 inches, or 12.7 to 21.6 centimeters. That works out to roughly 4 to 5 square feet of floor space by the formula above.

A 36 by 18 inch footprint, commonly sold as a 40 gallon breeder tank, is a reasonable long term minimum for an adult. Broadhead skinks grow larger, to about 12.75 inches in males.

Broadhead skinks are primarily arboreal. They hunt and nest on the ground but climb when not active. A blue tailed skink enclosure for this species benefits from extra height and secured branches.

Floor space matters more for the ground dwelling five lined and southeastern five lined skinks. Give them room to move, not just height.

Substrate for a Blue Tailed Skink Habitat Setup

Veterinary housing guidance for terrestrial lizards recommends newspaper, artificial turf, bark chips, or recycled paper pellets. It warns against loose gravel or pebbles because of ingestion risk during feeding. For a natural style setup, see the site’s bioactive enclosure guide for layering and drainage.

Match substrate moisture to the species. Five lined skinks come from moist deciduous forest with rotten logs and loose rock. A coconut fiber and topsoil blend that holds light moisture, without turning soggy, suits them well.

Southeastern five lined skinks favor drier pine forest and fallen wood. That species tolerates a drier mix with less frequent misting. Whichever blend you use, add several inches of depth so the skink can burrow.

These species dig and hide under cover rather than basking out in the open. Depth matters as much as moisture.

• Bottom layer: several inches of a coconut fiber or cypress mulch and topsoil blend for burrowing depth.
• Surface cover: leaf litter, flat bark pieces, and small rock slabs, to mimic the rocky habitat described for wild five lined skinks.
• Avoid: loose gravel, sand as a sole substrate, or anything small enough to be swallowed with prey.

Blue Tailed Skink Temperature Setup

The Merck Veterinary Manual gives a preferred zone of 68 to 91 degrees Fahrenheit (20 to 33 Celsius) for temperate and tropical reptiles. A basking spot should run 9 degrees Fahrenheit (5 Celsius) warmer than the air. Night temperatures should drop by the same 9 degrees.

Applied to a blue tailed skink enclosure, that means a basking surface of about 88 to 92 degrees Fahrenheit. The warm side air should sit in the low 80s. The cool side should stay at 72 to 76 degrees.

The nighttime low can drop to 65 to 70 degrees without extra heat. No published figure exists for this species specifically, so these are Merck’s general lizard numbers applied to a temperate woodland animal.

Use an overhead basking bulb on the warm end only. Never warm the whole enclosure evenly, since the skink needs zones to move between.

A digital thermostat keeps the basking bulb from overheating a small enclosure; see the thermostat guide for wiring one in. Check the basking surface and the cool side with a probe thermometer. A heat lamp dial is often several degrees off from the true surface reading.

Blue Tailed Skink Lighting and UVB

Broad spectrum UVB in the 290 to 300 nanometer range is required for vitamin D3 synthesis and calcium regulation in diurnal lizards. Fluorescent UVB tubes should sit within about 12 inches, or 30 centimeters, of the basking branch. Output drops off sharply with distance.

Run the light on a 12 hour photoperiod, to mimic a natural day and night cycle. The site’s guide to heating and UVB and the UVB lighting gear guide cover bulb types in more depth.

Five lined and southeastern five lined skinks spend much of the day under cover, in leaf litter or beneath logs. No published UV index target exists for them, so common keeper practice is a modest T8 or lower output T5 UVB tube rather than a high output desert bulb. The skink still needs a way to move fully into shade.

Replace fluorescent UVB tubes every 9 to 12 months, even if the bulb still lights. UVB output fades before visible light does. Mercury vapor bulbs supply both heat and UVB together and are typically rated for about a year as well.

Humidity, Water, and Hides

Wild five lined skinks live in habitat described as moist but not wet. Rock cover, rotten logs, and leaf litter hold ground level moisture there. Reproduce that by keeping the lower substrate lightly damp rather than dry.

For the air, the Merck Veterinary Manual lists 30 to 50 percent humidity for temperate zone reptiles. That is the target for the open part of the enclosure, with the damp substrate and a humid hide supplying the moisture the skink finds under cover. Merck also notes humidity needs rise during a shed.

Mist as needed rather than on a rigid schedule. Track humidity with a hygrometer rather than guessing; the site’s measurement gear guide covers hygrometer options. Southeastern five lined skinks tolerate the drier end of that range, in line with their pine forest habitat.

Provide a shallow water dish the skink can enter and exit easily. These are ground dwelling lizards, not climbers that drink from misted leaves alone. They need standing water within reach.

Include at least two hides, one on the warm end and one on the cool end. The skink should never have to choose between warmth and security. A humid hide, a small enclosed box packed with damp sphagnum moss, helps with shedding.

A humid hide is especially useful in the days after a skink drops and regrows its tail. The moisture speeds healing at the break point.

Full Blue Tailed Skink Enclosure Setup Checklist

Once the enclosure is running, feeding follows naturally from the housing. Five lined skinks and their relatives are insectivores. They hunt crickets, roaches, and similar prey among the leaf litter and rock cover.

The diet page covers feeding schedules and prey sizing by age. The breeding page is worth reading if your skink turns out to be a gravid female. Nesting behavior changes what the substrate needs to offer.

Frequently Asked Questions

What size enclosure does a blue tailed skink need?

A hatchling can start in a 5 to 10 gallon enclosure. An adult five lined or southeastern five lined skink runs 5 to 8.5 inches long. That size does best with roughly 4 to 5 square feet of floor space, commonly a 36 by 18 inch footprint such as a 40 gallon breeder tank.

Is it legal to keep a blue tailed skink I found?

It depends on the state. Some states protect native skinks or restrict collection without a permit. Connecticut lists the five lined skink as state threatened and advises leaving wild skinks alone; check your state wildlife agency before keeping one.

What temperature does a blue tailed skink enclosure need?

Merck’s general reptile guidance points to a basking surface of about 88 to 92 degrees Fahrenheit. The warm side air should sit in the low 80s, and the cool side at 72 to 76 degrees. The nighttime low should drop about 9 degrees, to 65 to 70.

Does a blue tailed skink need UVB lighting?

Yes. Diurnal lizards need broad spectrum UVB for vitamin D3 synthesis and calcium regulation. Provide it with a fluorescent tube placed within about 12 inches of the basking area, replaced every 9 to 12 months, alongside a shaded retreat the skink can use to escape the beam.

What substrate is best for a blue tailed skink habitat setup?

A coconut fiber and topsoil blend several inches deep works well for the five lined skink. Top it with leaf litter and bark or rock cover. Southeastern five lined skinks tolerate a somewhat drier mix, and loose gravel or sand should be avoided.

Why does the blue tail fade as the skink grows?

In five lined and related skinks, the bright blue juvenile tail darkens toward gray with age. Females more often keep some blue into adulthood. Adult males typically show duller gray tails, and in some species brighter head coloring during the breeding season.
