🐛 Rough woodlouse (Porcellio scaber)

📊Overview

One of the most widespread and hardy pet isopods, fast-breeding and available in dozens of color morphs (orange, dalmatian, 'lava'). Honest caveat: it cannot roll into a ball like Armadillidium, and its rapid breeding means a colony can overpopulate a small tub quickly.

🧭Temperament & needs

📈Compared with other Isopods

🧠Personality & temperament

Rough woodlice are hardy, active, and about as easy as a pet gets, which makes them a classic 'starter' isopod and a workhorse cleanup crew for bioactive terrariums. They roam the surface more than most species, especially at night, and breed so readily that a small culture soon becomes a thriving colony. They are undemanding and forgiving of beginner mistakes.

📜Origin & background

Native to Europe, Porcellio scaber has hitchhiked with human trade to become one of the most widespread land isopods on Earth. It turns up under logs, bark, and stones across temperate regions on nearly every continent.

🏃Exercise & enrichment

One of the more active isopods, they patrol the surface and climb bark and decor, so a varied terrain of cork, wood, and leaf litter keeps them occupied. Give them room to roam plus plenty of hides to explore and shelter under.

✂️Grooming & hygiene

No animal grooming is needed; upkeep is keeping one side of the enclosure moist and one drier, and removing mold or excess food. They molt in two halves and eat the shed skin, so molting needs no help from you.

🍽️Diet & feeding

Detritivores that eat leaf litter, rotting wood, vegetables, and a calcium source (cuttlebone or limestone), plus occasional protein such as fish flakes or dried shrimp. Feed a little every few days and clear away anything that begins to mold.

🏠Housing & environment

An easy species: a ventilated tub with a couple of inches of coco fiber and leaf-litter substrate, kept moist at one end and drier at the other, suits them well. Room temperature is fine (roughly 18-25C) and they tolerate a wide range; add cork bark, leaf litter, and a calcium source. Good cross-ventilation prevents a stuffy, mold-prone tank and keeps the colony thriving.

🩺Health & lifespan

Very hardy and among the most resilient isopods, with most losses coming from a bone-dry enclosure, no calcium (leading to molt failure), or overheating. Watch for grain mites and imbalance if the tank is kept too wet with food left sitting. Individuals live around 2-3 years while the colony continually replaces itself.

🎓Training & socialization

Not trainable, but they are one of the more handleable isopods and will simply wander across a palm during brief, gentle handling. Note that Porcellio cannot roll into a full ball like true pill bugs, and minimal handling with observation is still best.

💰Cost of ownership

Among the cheapest pets you can keep: a starter culture is inexpensive and everything else (substrate, leaf litter, calcium) is low-cost and long-lasting. They breed so fast that a single purchase can effectively supply you indefinitely.
