Orange Koi Isopods (Porcellionides pruinosus)

Orange Koi Isopods (Porcellionides pruinosus) are one of the most popular bioactive isopod morphs available today. Combining the hardiness and rapid reproduction of Porcellionides pruinosus with a vibrant orange and white “koi” pattern, these isopods are both highly functional and visually attractive.

Orange Koi Isopods are extremely active and spend much of their time exploring the enclosure surface, making them an excellent choice for keepers who want a clean-up crew that is frequently visible.

Why choose Orange Koi Isopods?

• Beautiful orange and white koi coloration
• Fast breeding and colony growth
• Highly active and visible species
• Excellent bioactive clean-up crew
• Suitable for beginners and experienced keepers

Orange Koi Isopods in bioactive terrariums

Orange Koi Isopods help break down decaying plant matter, leftover food, animal waste and other organic debris. Their constant activity contributes to a healthier substrate and supports nutrient recycling within the enclosure.

Due to their adaptability and high reproduction rate, Porcellionides pruinosus “Orange Koi” are commonly used in reptile, amphibian, invertebrate and planted bioactive setups.

Care Requirements
