Full Description
Here’s a complete care guide for the Black Water Leopard Gecko (Eublepharis macularius) — a rare melanistic morph line similar to the Black Night, known for its intensely dark body coloration and selectively bred traits.
Black Water Leopard Gecko Care Guide
Scientific Name: Eublepharis macularius
Morph Type: Line-bred melanistic morph
Similar To: Black Night, Black Pearl, Midnight
Note: “Black Water” is a line name, not a genetic mutation. Its care is identical to other leopard geckos, with special consideration for light sensitivity and stress reduction due to its dark pigmentation.
Morph Overview
| Trait | Description |
|---|---|
| Coloration | Very dark (charcoal to near-black), often with reduced patterning |
| Eyes | Dark brown to black |
| Pattern | Minimal or speckled; some may be nearly patternless |
| Genetics | Line-bred; not a simple dominant/recessive trait |
| Behavior | Similar to standard leos but may be more light-sensitive |
Size & Lifespan
| Feature | Details |
|---|---|
| Length | 7–10 inches (18–25 cm) |
| Weight | 50–90g (adult) |
| Lifespan | 15–20 years |
Enclosure Setup
Tank Size
| Age | Recommended Size |
|---|---|
| Juvenile | 10–20 gallons (long) |
| Adult | 20–40 gallon breeder |
Floor space is more important than height for leopard geckos.
Substrate
| Safe Choices | Avoid |
|---|---|
| Slate or ceramic tile | Loose sand (especially calcium sand) |
| Reptile carpet | Wood chips/bark |
| Paper towel (temp/quarantine) | |
| Packed soil/clay bioactive mix (advanced) |
Hides (Minimum 3)
-
Warm Hide — on the heated side
-
Cool Hide — on the opposite end
-
Humid Hide — filled with moist moss or coco fiber to aid shedding
Decor
-
Natural rocks, bark, fake or live plants
-
Enclosure with shaded areas to reduce stress from overhead lighting
-
Low basking surfaces (they are terrestrial)
️ Temperature & Humidity
| Zone | °F | °C |
|---|---|---|
| Warm side | 88–92°F | 31–33°C |
| Cool side | 75–80°F | 24–27°C |
| Nighttime | 68–75°F | 20–24°C |
| Humidity | 30–40% (ambient), 70–80% in humid hide |
Heating
-
Under Tank Heater (UTH) controlled by a thermostat is essential
-
Optional: Ceramic Heat Emitter (CHE) for nighttime temps
-
No need for overhead basking bulbs — they can cause stress
Lighting
-
UVB: Optional (low-level UVB such as 2.0–5.0 is beneficial but not required)
-
Day/Night Cycle: 12 hours light / 12 hours dark
-
Light Sensitivity: Black Water morphs benefit from low-light setups with shaded hides
Use indirect or dim lighting. Too much brightness can wash out coloration and cause stress.
️ Diet & Supplementation
Feeder Insects (gut-loaded)
| Insect | Notes |
|---|---|
| Dubia Roaches | High protein, easy to digest |
| Crickets | Affordable and active |
| BSF Larvae (Calciworms) | Great calcium source |
| Mealworms | Good in moderation |
| Superworms | Use sparingly (high fat) |
| Waxworms | Treat only |
Feeding Schedule
| Life Stage | Frequency |
|---|---|
| Juveniles | Daily |
| Adults | Every 2–3 days |
Supplements
| Supplement | Frequency |
|---|---|
| Calcium (no D3) | Always in tank |
| Calcium + D3 | 1–2× per week |
| Multivitamin | 1× per week |
✅ Dust insects with appropriate supplement before feeding
Maintenance
-
Daily: Remove droppings, replace water
-
Weekly: Clean hides and decor
-
Monthly: Deep clean the tank or refresh substrate (unless bioactive)
⚠️ Morph-Specific Considerations
| Issue | Recommendation |
|---|---|
| Light Sensitivity | Provide shaded hides and low ambient light |
| Stress Reactivity | Avoid bright lights and heavy handling |
| Color Fading | Overexposure to UV or stress may dull color |
| Genetic Line Strength | Source from ethical breeders to avoid inbreeding issues |
Handling Tips
| Tip | Why |
|---|---|
| Handle during evening | Matches their natural activity |
| Short sessions (5–10 min) | Reduces stress |
| Always support body | Prevents injury and builds trust |
| Avoid during shedding | Sensitive during this time |
✅ Quick Checklist
✔ 20–40 gal long tank
✔ UTH with thermostat
✔ 3 hides (warm, cool, moist)
✔ Gut-loaded insect diet
✔ Calcium + vitamin supplementation
✔ Ambient light control (dim is best)
✔ Spot-clean daily
✔ Clean, moist hide for shedding
✔ Gentle, infrequent handling
