Recommended Tank Sizes
Enclosure size guidance by life stage for Giant Day Gecko. General guidelines — always research species-specific requirements and size up whenever possible.
12" × 12" × 18" (~10 gal / 38 L) (30 × 30 × 46 cm)
18" × 18" × 24" (~25 gal / 95 L) (46 × 46 × 61 cm)
18" × 18" × 36" (~40 gal / 151 L) (46 × 46 × 91 cm)
24" × 24" × 48" (~65+ gal / 246+ L) (61 × 61 × 122 cm)
Ferguson Zone & UVB
The Ferguson Zone system categorizes reptiles by their natural UVB exposure needs, guiding lighting choices.
Tropical canopy species bask in filtered sunlight. Provide moderate UVB (5–10% T5) across part of the enclosure, with dense foliage for shade and cover.
Zone 1
Crepuscular / Shade
Zone 2
Occasional Basker
Zone 3
Open Sun Basker
Zone 4
Full Sun Lover
Temperature Gradient

Humidity

Lighting & Photoperiod
5–10% T5 HO UVB bulb. Basking bulb or LED grow lights for plants. 12 hr photoperiod year-round. Full-spectrum LED helps sustain live plants.
Heating
Overhead basking bulb or ceramic heat emitter. Heat panels for tall enclosures. Avoid heat mats for arboreal species — they offer little benefit.
Decor & Furnishings
- •Sturdy vertical branches and bamboo for climbing
- •Live plants (Pothos, Bromeliads, Philodendron)
- •Cork bark tubes and background for hiding
- •Misting system or fogger for humidity
- •Broad leaves as water-catching surfaces
Setup Notes
Maintain high humidity with daily misting or an automatic system. Use a drainage layer (LECA) under the substrate to prevent waterlogging. Provide good ventilation to prevent stagnant, moldy air.
