Isopod Care Guide

Overview

Isopods are nature’s cleanup crew — detritivores that feed on decaying organic matter, helping recycle nutrients and maintain healthy bioactive soil conditions. In a terrarium or vivarium, they break down waste, improve aeration, and serve as supplemental feeders for some amphibians and reptiles.

Enclosure Setup

  • Container: For cultures, use a 6–16 qt plastic tub with a tight-fitting lid. Add ventilation holes on both sides for cross airflow (covered with fine mesh).
  • Substrate: 2–3 inches of Microterra Bioactive Substrate or a mix of organic topsoil, coco fiber, leaf compost, and sand.
  • Moisture Zones: Maintain a moist half (regularly misted) and a drier half (for burrowing). Isopods self-regulate by moving between zones.
  • Leaf Litter: Add a generous layer of dried hardwood leaves (oak, magnolia, maple). Replace as they’re consumed.
  • Hides: Cork bark, curved wood, or pieces of egg crate provide cover and surface area.

Temperature & Humidity

  • Temperature Range: 70–80°F is optimal.
  • Humidity: 70–90% depending on species. Mist lightly every 2–3 days; never let substrate dry out completely.
  • Lighting: Ambient room light is fine; avoid direct sunlight or heat lamps.

Feeding

  • Primary Diet: Leaf litter and decaying wood are staples.
  • Supplements: Add small amounts of vegetables (sliced zucchini, sweet potato, carrot) once weekly. Remove leftovers before mold develops.
  • Calcium Source: Provide crushed eggshell, cuttlebone, or limestone chips to support exoskeleton health.
  • Protein Boost (Optional): Dried shrimp, fish flakes, or small bits of reptile chow once per week encourage reproduction.

Maintenance

  • Spot clean debris and mold as needed.
  • Add fresh substrate every few months to maintain nutrient balance.
  • Split and rehouse colonies once populations exceed 300–400 individuals to prevent crowding.

Species Notes

  • Powder Orange / Powder Blue (Porcellionides pruinosus): Fast-breeding, surface-active, excellent generalists.
  • Oreo Crumble (Porcellio laevis): Larger, bold, enjoy slightly drier zones.
  • Orange Cream (Porcellio scaber): Hardy, slower-breeding, excellent for display tanks.
  • Dwarf White (Trichorhina tomentosa): Fully subterranean, ideal for humid enclosures and amphibian setups.
