Overview
The Powder Orange Isopod is the workhorse of bioactive terrariums - a quick, prolific, apricot-colored woodlouse with a frosted finish that tolerates nearly any conditions and cleans up after nearly any animal. Average lifespan is 1-2 years, offset by relentless breeding. (Porcellionides pruinosus 'Powder Orange'.)
Origin & Habitat
A bright orange form of a fast-moving cosmopolitan species, powdered with the frosted bloom that names the group.
Appearance
1-1.2 cm, soft orange overlaid with a powdery blue-white bloom, on long quick legs - they scurry rather than trundle.
Temperament & Handling
The busiest isopod in the trade: fast, surface-active and always working. Harmless to tankmates large and small, which is why it's the default clean-up crew.
Enclosure
Any ventilated tub from shoebox size up, with coco-leaf substrate, bark hides and the standard damp-to-dry gradient. Equally happy loose in a bioactive vivarium.
Heating, Humidity, Lighting
The tolerance champion: 18-29°C and almost any humidity with a moist refuge. This flexibility - not looks - made it ubiquitous.
Diet
Leaf litter, decaying wood, scraps, and it excels on animal waste in vivariums - the actual job description. Cuttlebone for calcium; light protein now and then.
Health & Lifespan
Nearly unkillable as a colony; individuals are short-lived (1-2 years) but reproduction outruns mortality effortlessly. The standard beginner-can't-fail species.
Pros & Cons
Pros
- Best clean-up crew in the hobby
- Thrives in almost any conditions
- Pretty frosted-orange color at a tiny price
Cons
- Individuals short-lived
- Too quick to 'handle' meaningfully
- Can overpopulate small sealed tanks
Powder Orange Isopod - frequently asked questions
Powder Orange or Dairy Cow for a vivarium?
Powder Orange - smaller, gentler with tank inhabitants and faster at waste processing. Dairy Cows are better as a display colony in their own tub.
What's the powdery coating?
A natural waxy 'pruinose' bloom, like on a plum - the species name pruinosus means frosted. It's healthy, not fungus.
How many do I need to start?
A dozen seeds a vivarium; within two or three months at room temperature the population self-sustains.
