Your giant day gecko can't tell you the viv has crept too warm or the humidity has dropped. baskr watches the pattern across your logs, temperature, humidity, weight and feeding, and shows you what needs attention before it becomes a problem.

Giant Day Gecko
Humidity dropping
Averaged 48% vs the 60–80% it needs. Increase misting.
Warm zone
28–30°C · 82–86°F
Ambient
24–27°C · 75–81°F
Humidity
60–80%
Ideal ranges for Phelsuma grandis, the same targets baskr scores your logs against.
Basking and warm figures are surface temperatures at the spot; cool and ambient are air. Measure with a probe or infrared thermometer at the animal's height.
Diurnal
Active by day
Northern Madagascar
Wild climate. Warm, humid tropical forest of northern Madagascar; bright warm days, humid air and seasonal rains.
Why the care is what it is. This is why baskr targets a 28 to 30°C warm zone, 60 to 80% humidity, real UVB for a diurnal basker, and a tall, bamboo-planted vivarium.
Logging is the input. The product is spotting when a single off reading becomes a pattern worth acting on.
28–30°C (82–86°F), no hotter
Too hot stresses it; too cool and it slows down and stops feeding.
60–80% with daily misting
Too dry brings bad sheds and dehydration; stagnant damp risks respiratory infection.
6% over the basking area, renewed yearly
Weak UVB risks metabolic bone disease in an active day gecko.
Insects plus a day-gecko diet, calcium-dusted
Refusals or lethargy warrant checking warmth, prey size and calcium.
Steady, watch egg-laying females
A downward trend or thinning tail base is a red flag.
Clean, complete sheds
Stuck shed on toes needs more humidity.
Safe to include
Avoid
A heavily planted bioactive viv holds humidity and gives climbing routes; bamboo is a signature feature.
Staples
Occasional / treats
Never feed
Supplements. Calcium at most feeds (with D3 per your UVB) and a multivitamin about weekly. Calcium is critical, especially for egg-laying females.
Good to know. It eats much like a crested gecko plus live prey: a day-gecko diet plus insects. Keep calcium up.
The right kind of kit, pick brands you trust.
UVB lighting
A 6% T5 HO tube (Ferguson zone 2–3) over the basking area, replaced every 12 months.
Basking heat
A gentle basking source to reach 28–30°C at the top, on a thermostat.
Thermostat
Controls the heat so a planted viv can't overheat.
Misting
Daily misting for humidity and drinking droplets, with airflow so it dries between sprays.
Thermometer + hygrometer
To track the warm zone and 60–80% humidity.
Tall planted enclosure
A tall, planted glass or fine-mesh vivarium.
Grounded in your own logs and the ideal ranges above, plain language, never a diagnosis.
Humidity averaged 48% this week, below the 60–80% a giant day gecko needs. Increase misting before it affects sheds.
Warm zone hit 33°C, hot for this gecko. Ease the bulb so it can't overheat.
No feeding logged in several days. Check warmth, prey size and calcium.

A quick guide, not a diagnosis. Ideal ranges vary with age, morph and setup, and individual animals differ, so confirm anything critical with an experienced keeper or a reptile vet.
Not really. Their skin tears easily and they can drop their tail, so they're a display gecko, best watched rather than held.
Insects plus a powdered day-gecko diet and a little fruit, much like a crested gecko plus live prey. Keep calcium up, especially for females.
Yes. Unlike most geckos it's diurnal and genuinely benefits from UVB over the basking spot.
A single, or an established male-female pair, in a large planted viv. Males fight, so never house two males together.
