The Red Koi Isopod (Porcellionides pruinosus) is a bold, high-visibility isopod prized for its energetic surface activity and striking red marbled patterning. Their coloration ranges from soft mottled reds to deep maroon spotting, giving each individual a beautifully unpredictable, almost koi-fish inspired appearance. If you’ve ever wanted an isopod species you’ll actually see moving around your enclosure, Red Koi will quickly become a favorite. These little powerhouses are fast, curious, and constantly on the surface — perfect for keepers who love observing their cleanup crew in action and ideal for reptiles with natural foraging or “hunting” instincts. Raised on Microforest soil blends and fed exclusively with our homemade Isopod Superfood, our Red Koi display exceptional color, vigor, and colony stability from the moment they arrive. Behavior & Activity Red Koi Isopods are extremely surface active — far more visible than most isopod species. Expect to see them darting across the substrate, exploring leaf litter, and clustering around hides. They’re quick, responsive, and always up to something. They especially love hiding and congregating inside cholla wood and beneath cork bark, making these two items ideal enrichments for their enclosure. If visibility matters to you, Red Koi are unmatched. Colony Growth & Breeding Red Koi are one of the fastest-breeding isopod species available. Once settled, colonies can expand quickly and consistently. You may even notice tiny babies sooner than expected — they waste no time building numbers. Because of their fast reproduction, they benefit greatly from a high-protein diet, making our Isopod Superfood the perfect nutritional foundation for color, growth, and colony stability.
