Your ackie can't tell you the basking surface has cooled or that it's stopped digging. baskr watches the pattern across your logs, temperature, humidity, weight and feeding, and shows you what needs attention before it becomes a problem.

Ackie Monitor
Basking too cool
Surface averaged 44°C vs the 50–65°C an ackie needs. Check the basking bulbs and stack.
Basking surface
50–65°C · 122–150°F
Ambient
26–30°C · 79–86°F
Humidity
40–60% (humid burrow)
Ideal ranges for Varanus acanthurus, 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
Arid northern Australia
Wild climate. Hot, arid rocky ranges and spinifex of northern Australia; blazing days, cooler nights, and deep burrows to escape the heat.
Why the care is what it is. This is why baskr targets a fierce 50 to 65°C basking surface, strong UVB and deep, slightly damp substrate for burrowing, not a bare tank.
Logging is the input. The product is spotting when a single off reading becomes a pattern worth acting on.
A very hot surface of 50–65°C (122–150°F) on stacked rock or slate
Too cool and this high-drive lizard can't digest or thermoregulate, ackies need real heat.
Ambient 26–30°C with a cool end around 24°C
No gradient leaves a big, active lizard nowhere to cool down.
Deep, slightly damp substrate holding burrows, ~40–60% with a humid layer below
Substrate too shallow or bone-dry and burrows collapse while sheds and hydration suffer.
Steady; ackies run to obesity on rich, fatty diets
A sharp gain from too much fatty prey, or a real drop, both warrant a closer look.
Insects and lean protein, gut-loaded and calcium-dusted; often for juveniles, measured for adults
Off food often means the basking surface is too cool, check heat before anything else.
Clean sheds and daily digging and foraging
A normally busy ackie gone still and hidden for days is worth investigating.
Safe to include
Avoid
Ackies dig and bulldoze, so most keepers build a hardscape of rock, cork and deep substrate rather than a planted display.
Staples
Occasional / treats
Never feed
Supplements. Dust feeders with calcium and use a reptile multivitamin regularly, especially for growing juveniles.
Good to know. A high-drive carnivore, mostly insects for adults with occasional richer items. Feed juveniles often; measure adults to avoid obesity.
The right kind of kit, pick brands you trust.
UVB lighting
A high-output 10–12% T5 HO tube (Ferguson zone 3) over the basking platform, replaced every 12 months.
Basking heat
A cluster of basking bulbs (often halogen floods over stacked rock) to hit a 50–65°C surface, on a dimming thermostat.
Thermostat
A dimming or pulse thermostat to hold that hot basking zone safely.
IR/probe thermometer + hygrometer
A surface or infrared thermometer for the basking rock, plus ambient and humidity tracking.
Deep substrate
20–30 cm+ of a soil and sand mix that packs and holds a burrow, kept damp underneath.
Enclosure
A large, robust wood or PVC enclosure with a secure lid, an ackie is powerful and shifts decor.
Grounded in your own logs and the ideal ranges above, plain language, never a diagnosis.
Basking surface has averaged 44°C this week, cool for an ackie (target 50–65°C). Check the basking bulbs and stack, digestion depends on real heat.
Weight has climbed steadily on frequent rodent feeds. Shift toward leaner insects and space meals to avoid obesity.
Digging and surface activity have dropped off for several days. Check basking heat and substrate depth and moisture.

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.
They're the most beginner-accessible monitor, but that's relative: they still need a large enclosure, a very hot basking zone, strong UVB, deep substrate and a real feeding routine. Think dedicated intermediate keeper, not an easy first lizard.
Around 60–70 cm (24–28 in) total length including the spiny tail. Small for a monitor, but a big, active presence that needs a 6×3 ft-plus enclosure.
Yes. A localised basking surface of roughly 50–65°C is normal and important, monitors bask hard and briefly to power digestion. It must be paired with a proper cool end so they can regulate.
Often, yes. They're intelligent and food-motivated, and with calm, consistent routine many become confident and interactive. Go at the animal's pace.
