Mourning Gecko Care Guide: 17 Key Tips

If you’re researching mourning gecko care, prepare yourself for one of the weirdest—and frankly coolest—reptiles in the hobby.

These tiny geckos look adorable, climb like caffeinated ninjas, and reproduce without males like nature accidentally turned on creative mode.

Yes… really.

Mourning geckos are famous for being:

tiny escape artists
surprisingly active
ridiculously fun to watch
and biologically confusing enough to make your high school science teacher proud

But despite their size, mourning gecko care isn’t as simple as “put gecko in tank, add bug, hope for best.”

They have very specific humidity, enclosure, feeding, and heating needs.

And if you get them wrong?

Well… your gecko may start protesting harder than a cat being introduced to bath water.

What Is a Mourning Gecko?

The mourning gecko (Lepidodactylus lugubris) is a tiny tropical gecko species known for its:

all-female colonies
parthenogenetic reproduction
arboreal climbing behavior
small adult size
communal nature

Unlike many pet reptiles, these geckos can reproduce without males.

That means:

Buy two females?
Congratulations.
You may have accidentally started a tiny gecko empire.

Why Mourning Geckos Are So Popular

There’s a reason reptile keepers love them:

Pros

Beginner-friendly once setup is correct
Small enclosure footprint
Very active and entertaining
Fascinating breeding behavior
Can live communally
Great display pets

Cons

Extremely fast
Difficult to handle
Escape artists of Olympic caliber
Tiny babies can fit through absurdly small gaps

Think of them as:

“The Ferrari of tiny geckos—fast, beautiful, and absolutely gone if you leave the door open for 0.4 seconds.”

Mourning Gecko Size: How Big Do They Get?

Adult mourning geckos typically reach:

Average Size

3 to 4 inches total length
Around 2–5 grams

That makes them:

Roughly the size of a very determined house key.

Despite their tiny size, they use every inch of vertical space available.

Mourning Gecko Lifespan

With proper mourning gecko care, lifespan is typically:

8–10 years average
Some live 10+ years

That’s a solid commitment for a reptile smaller than your thumb.

Mourning Gecko Enclosure Setup

A proper setup is one of the most important parts of mourning gecko care.

Minimum Tank Size

For 1–3 adults:

12x12x18 inches minimum

Better options:

18x18x24 inches

Vertical space matters more than floor space.

Why?

Because mourning geckos are arboreal.

They don’t want a mansion.

They want a treehouse.

For broader reptile husbandry guidance and evidence-based gecko care practices, the ReptiFiles reptile care resource library offers excellent educational information used by many reptile keepers.

Mourning Gecko Tank Setup Essentials

Your enclosure should include:

Climbing Branches

Provide:

Cork bark
Driftwood
Vertical branches
Bamboo

Dense Foliage

Use:

Pothos
Fake vines
Bromeliads
Hanging plants

Hides

Even arboreal geckos want privacy.

Provide:

Elevated cork tubes
Plant cover
Hidden ledges

Substrate for Mourning Geckos

Best options:

Coconut fiber
Bioactive substrate
ABG mix
Paper towel (quarantine only)

Avoid:

Dry desert substrates
Loose sand
Walnut shell

Because yes—

Tiny gecko + giant substrate chunk = bad math.

Temperature for Mourning Gecko Care

Ideal ambient temperatures:

Daytime

75–82°F (24–28°C)

Warm Spot

82–85°F max

Night

70–75°F

Avoid overheating.

Mourning geckos are tropical—not tiny dragons.

Do Mourning Geckos Need Heat?

Usually:

Yes, if your room is below 72°F regularly.

Use:

Low wattage heat lamp
Nano ceramic heater
Overhead heating preferred

Avoid heat mats when possible.

They climb.

They don’t sit on the floor like leopard geckos waiting for room service.

Do Mourning Geckos Need UVB?

This is one of the most searched questions in mourning gecko care.

Short Answer:

UVB is highly recommended.

Best setup:

2–5% UVB bulb
Shade options throughout enclosure

Benefits include:

Better calcium metabolism
More natural behavior
Improved long-term health

Can they survive without UVB?

Sometimes.

Should you skip it?

Not if you want optimal husbandry.

Mourning Gecko Humidity Requirements

Ideal humidity:

60–80%

Allow natural fluctuations:

Higher after misting
Lower during daytime dry-out

Misting Schedule

Typically:

1–2 times daily

Your tank should not stay swampy 24/7.

If it smells like a Florida marsh…

You have overdone it.

What Do Mourning Geckos Eat?

Diet includes:

Primary Foods

Crested gecko diet / gecko MRP
Small feeder insects

Best Feeder Insects

Flightless fruit flies
Pinhead crickets
Small roaches
Bean beetles

Can Mourning Geckos Eat Fruit?

Technically some lick fruit…

But do not rely on fruit.

Use proper formulated gecko diet instead.

Fruit alone is like feeding your child only applesauce and hoping algebra works out.

Feeding Schedule for Mourning Geckos

Adults

CGD / prepared diet: 3–4x weekly
Insects: 1–2x weekly

Juveniles

Feed more frequently

Always dust insects with calcium.

Are Mourning Geckos Good Pets?

Yes—if you want a display pet.

No—if you want a cuddly reptile.

They are:

not ideal for handling
too fast for beginners wanting interaction
better for observing than touching

Think:

“Tiny rainforest TV subscription.”

Can Mourning Geckos Live Together?

Yes.

In fact, communal setups are common.

Keep Them In:

Female groups
Similar-sized individuals

Monitor for:

Bullying
Food competition
Dominance behavior

Are All Mourning Geckos Female?

Nearly all captive mourning geckos are female.

That’s why this species is famous.

How Do Mourning Geckos Reproduce?

Through parthenogenesis.

Meaning:

Females clone themselves.

Nature really said:

“We don’t need males for this one.”

Do Mourning Geckos Reproduce Asexually?

Yes.

This is one of the coolest facts in reptile keeping.

A single female can produce fertile eggs without mating.

Mourning Gecko Eggs and Breeding

Females lay:

Usually 2 eggs at a time
Every 4–6 weeks

Eggs are often glued to surfaces.

Which means removing them can be…

An emotional experience.

Baby Mourning Gecko Care

Baby mourning geckos are:

Extremely tiny
Extremely fast
Extremely capable of vanishing into alternate dimensions

Raise separately if needed.

Use:

Tiny secure grow-out enclosures
Paper towel substrate
Frequent misting
Small food portions

Common Mourning Gecko Care Mistakes

1. Underestimating Escape Risk

They fit through absurdly tiny gaps.

2. Tank Too Dry

They are tropical geckos.

Not crunchy geckos.

3. No Vertical Space

Horizontal tanks waste their natural behavior.

4. No UVB

Survival ≠ thriving.

5. Overhandling

These are display animals.

Not pocket lizards.

Bioactive Setup for Mourning Geckos

Bioactive works exceptionally well because:

They love planted enclosures
Humidity is easier to maintain
Looks stunning
Encourages natural behavior

Recommended cleanup crew:

Springtails
Isopods (small species)

Are Mourning Geckos Beginner Friendly?

Yes—with caveats.

They are beginner-friendly if:

You want a display gecko
You understand humidity/husbandry basics
You can secure an enclosure properly

They are NOT ideal if:

You want handling
You dislike insects
You panic when tiny things move quickly

Final Verdict: Is Mourning Gecko Care Easy?

Once setup is dialed in?

Yes.

But they require more precision than many beginners expect.

They may be tiny…

Yet they somehow carry the energy of:

a parkour athlete
a magician
and a tax auditor looking for enclosure weaknesses

Get their environment right, and mourning geckos become one of the most fascinating micro-reptiles in the hobby.

Yes, mourning gecko care is beginner friendly for keepers who want a display pet rather than a handling reptile. They are easy to maintain once humidity, temperature, and enclosure setup are correct.

For proper mourning gecko care, a vertical 12x12x18 enclosure is the minimum for a small group, though larger planted terrariums are strongly recommended.

While some keepers raise them without UVB, modern mourning gecko care standards recommend low-level UVB lighting to support calcium metabolism and natural behavior.

Successful mourning gecko care requires humidity between 60% and 80%, with natural daily fluctuations after misting.

A balanced mourning gecko care diet includes crested gecko diet or other prepared gecko formulas along with tiny feeder insects like fruit flies or pinhead crickets.

Yes, communal housing is common in mourning gecko care, and they often do well in female groups when enough space and hiding spots are provided.

One of the most unique parts of mourning gecko care is understanding that they reproduce through parthenogenesis, meaning females can produce fertile eggs without males.
