Porcellionides pruinosus - Orange Koi Isopods

Porcellionides pruinosus Orange Koi are popular terrarium isopods known for their distinctive orange coloration and active behaviour. Thanks to its size, rapid reproduction and attractive appearance, it is one of the most commonly bred species in bioactive terrariums and as an independent breeding colony.

Characteristics and appearance

Orange Koi, a variant of Porcellionides pruinosus, is characterized by a deep orange to marbled pattern that stands out on a dark substrate. Adults grow approximately 1–1.5 cm and are very mobile. This species is unpretentious and suitable even for novice isopod breeders.

Breeding and conditions

For the successful breeding of Orange Koi isopods, a high-quality substrate, sufficient shelters and stable humidity are important. A bioactive mixture with an admixture of leaf and pieces of rotting wood is ideal. The colony will also appreciate the bark, moss and leaves, which provide shelter and a natural source of food.

• Temperature: approx. 20-26 °C
• Humidity: wetter part of the box + drier zone
• Feeding: vegetables, leaves, fish food, calcium (cuttlefish bone)

Use in bioactive terrariums

Porcellionides pruinosus Orange Koi are an ideal cleaning crew for bioactive terrariums with reptiles, amphibians and invertebrates. They help break down food debris, droppings, and dead plant parts, thus supporting a healthy ecosystem. Thanks to its rapid reproduction, the colony is easy to maintain and stabilizes the environment for a long time.
