🔍 At A Glance: Crystal White Isopod Husbandry Summary
Scientific Name: Porcellio laevis (Crystal White Morph)
Common Names: Crystal White Isopods
Adult Size & Lifespan: 1–2 cm | Adults can live up to 2 years
Life Cycle Timeframe: Exceptionally rapid; completes a full life cycle in approximately two months
Breeding Rate: High; explosive population growth once established (among the most prolific Porcellio species)
Ideal Climate: Temperature: 18–23°C (20–22°C for optimal results) | Humidity: 60–80% (70–80% preferred)
Physical Identification: Completely stark white, translucent-leaning morph with a entirely smooth dorsal surface, two pairs of pleopodal lungs, and distinctive spear-shaped uropods visible on mature males.
Enclosure Sizing Guide: Starter cultures of 10–20 individuals thrive in a 20x15x15cm environment; large breeding master colonies scale up cleanly into a 40x20x20cm ventilated storage container setup.
Dietary Base: Detritivore essentials (Hardwood leaf litter, rotten hardwood, premium edible flake soil, organic waste, and damp sphagnum moss)
Supplemental Nutrition: High-protein sources (fish flakes, shrimp pellets, nutritional yeast) fed 1–2 times per week + constant calcium access (crushed cuttlebone or eggshells)

Explore the sections below for our biology-led guide on dietary requirements, humidity gradients, and the rapid lifecycle of these iconic crystal white isopods.
- Size & Life Cycle: Porcellio laevis are one of the larger species of isopod, with adults reaching anywhere between 1-2cm. P. laevis can complete their life cycle in around two months, and adults can live for up to two years.
- Morphology: This species can come in a variety of colour morphs, but typically all have a smooth dorsal surface, two pairs of pleopodal, or ‘external’ lungs, and males can easily be identified by their long, ‘spear-shaped’ uropods.
- Establishment time: We suggest adding any clean-up crew 7-14 days prior to adding other inhabitants, to ensure the colony has enough time to establish itself within their new environment.
- Protein hungry: Bare in mind this species is very protein hungry, so can sometimes do more harm than good for certain reptiles when moulting if their population is not kept in check.
