Rubber Ducky Isopod

Cubaris sp. 'Rubber Ducky'ไอโซพอด

Narrower than the page we cite. The source we cite, read on 10 Aug 2026, gives a wider range than the one above. The narrowing is ours and nobody here has written down why. krawlo.com

The way of life is written in this sheet, word for word. The climate words summarise the two figures above them, they do not add to them.

The numbers

Temperature

152025303540 °C
24–27°Ambient

One ambient band, 24–27°C. This sheet states no warm side, no cool side and no night figure, so none are shown. Same scale on every sheet here, so two species compare by eye.

Humidity

Enclosure
6 L+ tub, 15 cm deep substrate, humid

The size the sheet states for a grown animal.

Why

Two drawings, because they answer two questions. The silhouette is at true scale against a 1.75 m person: it says how big this animal actually is, which no number does for someone who has never seen one. The bar under it is logarithmic and shared by every sheet here, so a 2 cm isopod and a 4 m python both stay readable on the same axis and two species can be compared at a glance.

What your climate adds

This sheet states a range to hold. Your local climate decides how much work holding it is. Pick the nearest city: nothing is sent anywhere, the choice stays in this browser.

Diet

Feeding rhythm

every 7 dAs the sheet states
4Meals in 28 days

Twenty-eight days, one row. Each band is a meal window.

Why

The windows widen as they go because the interval is a range: four meals after a 10–14 day cycle land anywhere between day 40 and day 56.

The sheet statesLeaf litter, rotting wood, decaying plant matter · Continuous access; add protein/veg weekly

Staple food
Leaf litter, rotting wood, decaying plant matter
Feeding frequency
Continuous access; add protein/veg weekly
Supplements
Cuttlebone / crushed limestone always available (calcium)

Behaviour and handling

HandlingSafe; harmless: but minimise disturbance to breeding colonies
CommunalYes – colony/communal, keep as a group
Defense / stress signsRolling into a ball, hiding, colony stalls if too dry

Reproduction

Life course

Day 0Hatch
2–3 yrLifespan in care
2 yrMinimum commitment
Sexual maturityNot in our data

Read from the lifespan and maturity the sheet states, for animals in care and not in the wild.

Why

The minimum commitment is the low end of that lifespan, and the reproductive window is what is left after maturity: both are subtractions on stated figures, not figures of their own.

Reproduction
Broods young in a marsupium; slow but year-round once established

Common health problems

Common health issues
SignsColony crash from low humidity or lack of calcium; mite overgrowth
Red flags / quarantine
SignsQuarantine new stock; watch for grain mites and mould

Good to know

  • Its yellow face-plate and round body look uncannily like a rubber duck.

Not stated: The size of the enclosurethis sheet describes the enclosure without a figure: « 6 L+ tub, 15 cm deep substrate, humid »

Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation. What the sheet does not state is listed too, rather than left out: a kit that looks complete is worse than one that names its gap.

This sheet states 6 of 7 of the fields this product runs on. What is missing turns something off: day/night engine and awake count on the globe. We show the gap rather than fill it with a plausible number.

UVB is measured but does not count: it is absent from 421 of 678 sheets, and on most of them that is not a gap, since a nocturnal snake's sheet has no reason to state a UV index. Counting it would call the library incomplete without cause.
