Overview
The Porcellio scaber 'Dalmatian' variety showcases a stunning white to cream-colored base with random dark gray to black spots scattered across their dorsal surface, creating the distinctive dalmatian dog pattern that gives them their name. Pattern intensity varies dramatically between individuals—some display heavily spotted coats while others remain nearly pure white with minimal markings. Interestingly, juveniles often start completely white and develop their characteristic spots as they age and molt, making colony observation particularly rewarding.
These remarkable isopods represent one of the first colour morphs to enter the hobby, pioneering the breeding community that exists today. Unlike their pill bug cousins, Porcellio scaber cannot roll into a ball when threatened, instead adopting a "playing dead" posture while remaining surprisingly active and fast-moving compared to many species. Their adaptability to varying moisture levels makes them exceptionally forgiving for beginners, though they still require proper environmental gradients to thrive.
As excellent cleanup crew members, dalmatian isopods process organic waste efficiently while contributing essential minerals to bioactive substrates through their molted exoskeletons. Their moderate size and gentle temperament make them suitable for educational purposes, and their prolific breeding habits ensure sustainable colonies that can support multiple enclosures or bioactive setups.
Basic Care
Temperature management is straightforward with dalmatians, as they thrive at standard room temperatures between 75-80°F, though they can tolerate a broader range from 60-90°F. These hardy isopods are more cold-tolerant than many species while remaining comfortable in typical household conditions. Understanding proper humidity and moisture management is crucial for their well-being, requiring a moisture gradient from damp to dry areas rather than uniform humidity throughout their enclosure.
Ventilation plays a critical role in dalmatian success, as poor airflow can lead to sudden colony crashes from CO2 buildup. Create multiple ventilation holes around the container circumference, not just the lid, to ensure proper cross-ventilation. The complete beginner's guide to keeping isopods provides detailed setup instructions that work excellently for this species.
Feeding dalmatians centers around providing a thick layer of quality leaf litter as their primary food source, supplemented 1-2 times weekly with small portions of fresh vegetables like zucchini, carrots, or squash. Remove uneaten fresh food within 2-3 days to prevent mold development, following the guidelines in our comprehensive isopod feeding guide.
Substrate Mix
Create an ideal habitat using a base of organic potting soil or worm castings mixed with sphagnum moss for moisture retention and structure. Avoid waterlogged conditions while maintaining adequate dampness for proper molting. The substrate should be 2-3 inches deep to allow natural burrowing behavior, with the surface completely covered by a thick layer of quality leaf litter.
For optimal results, establish a moisture gradient by concentrating sphagnum moss and additional misting on one side while keeping the opposite end well-ventilated and drier. This setup allows dalmatians to self-regulate their moisture needs by moving between areas. Include pieces of cork bark, rotting white wood, or other hiding spots throughout the enclosure to provide security and additional feeding opportunities.
Essential calcium supplementation can be provided through cuttlebone pieces, crushed oyster shell, or specialized calcium supplements placed strategically around the enclosure. The detailed isopod substrate guide offers comprehensive mixing ratios and preparation techniques that work exceptionally well for Porcellio scaber varieties.
