Isopod Care Hub
Isopods are detritivores, meaning they primarily eat decaying organic matter. A varied diet keeps colonies healthy and breeding consistently.
Staple Foods (Always Available)
- Leaf litter — oak, magnolia, or maple leaves, replenished every few weeks
- Decaying wood — cork bark or untreated hardwood breaks down slowly and provides constant grazing material
Supplemental Foods (1-2x per week)
- Fish flakes or pellets — high in protein, isopods are drawn to them quickly
- Vegetable scraps — carrots, zucchini, spinach, cucumber
- Dry dog food (crushed) — an occasional protein boost
Calcium Sources (Critical for Molting)
- Cuttlebone — crushed or left whole for isopods to graze on
- Crushed eggshell — a free, easy calcium source
Calcium deficiency is one of the most common causes of failed molts. Always keep a calcium source available in the enclosure.
Feeding Schedule
Feed supplemental foods 1-2 times per week in small amounts. Remove any uneaten fresh food (vegetables, fish flakes) after 24-48 hours to prevent mold buildup — leaf litter and wood can stay indefinitely since they break down naturally.
Signs of Overfeeding
Excess mold, fruit fly infestations, or a strong odor usually mean you’re feeding too much or leaving food in too long. Cut back and remove leftovers more promptly.
