How to keep Penguin isopods

• Stable humidity matters, so don't let the whole tub dry out.
• Use deep substrate, with a steady supply of leaf litter and decaying wood.
• Expect slower breeding than beginner species.
• Feed leaf litter and decaying hardwood as a staple, with cuttlebone for calcium and a small pinch of protein (fish flakes or dried shrimp) once a week.
• Use a tub with small vents and deep organic substrate (topsoil, coco fibre, leaf litter), with cork bark for hides.
