Protein is a supplement, not the base of an isopod diet. Leaf litter, decayed wood, and the organic substrate remain the constant foods. Protein is useful when the portion matches what the colony can finish quickly.
Choose dry, simple foods
Quality insect-based diets, dried crustacean, or suitable fish foods are common choices. Avoid oily, seasoned, salty, or spoiled table food. Read labels and use foods intended for animal feeding.
Start smaller than expected
For a new or slow colony, begin with a crumb rather than a full pellet. Place it on a dry leaf, bark chip, or feeding dish. If a noticeable amount remains after a day, remove it and offer less next time.
Watch the enclosure, not the calendar
- Rapid removal with no odor can justify a slightly larger portion.
- Mold, mites, gnats, or a sour smell mean portions are too large or too frequent.
- Pregnant females and fast-growing colonies may use more than small starter groups.
- Warm conditions speed spoilage as well as appetite.
Do not mistake protein for a cure
Poor molts or population decline can also come from moisture, ventilation, contamination, or substrate problems. Adding more protein will not correct an unstable habitat.
Quick checklist
- Leaf litter remains the staple
- Protein placed on removable surface
- Leftovers checked within 24 hours
- Portion reduced after spoilage
