Caring for Porcellio magnificus

Porcellio magnificus stands out because of its size and long, light-colored antennae. This Isopod is primarily a pet to observe in its own, well-ventilated enclosure and is not a one-size-fits-all cleaning solution for a terrarium.

The temperature figures are approximate values based on previous experience. Measure the temperature at the location of the box. Direct sunlight and an uncontrolled heat source can quickly cause the container to overheat.

Caring for Porcellio magnificus: Enclosure and Environment

Choose an escape-proof box with securely covered ventilation openings. Larger species and growing groups require more floor space. Fill the enclosure with several centimeters of nutrient-rich soil and cover it with decomposed leaves. Flat pieces of bark provide hiding places. Pure coconut fiber is not a sufficient food source.

Most of the surface tends to stay dry. However, one corner—under leaves or moss—must remain slightly moist at all times. Moisten this hiding spot specifically, rather than spraying the entire container. Good ventilation prevents moist air from becoming trapped.

Food for Porcellio magnificus

Leaves and white-rotten hardwood should always be kept in the box. They serve as both food and shelter. You can collect clean, suitable leaves yourself; if you don’t have a safe place to collect them, pre-prepared leaf litter is a practical alternative.

A source of calcium supplements their diet. Cuttlefish powder can be offered sparingly in an easily accessible spot. Small portions of earthworm food are a supplement, not a substitute for leaves and wood. Check for leftovers the next day and remove any perishable items promptly.

Behavior and Offspring

These animals can be very agile and share hiding spots. Provide plenty of floor space and several large pieces of bark. A damp corner gives them options without keeping the entire floor wet.

In our experience, growth was slow and could take about a year. Accordingly, you should let a new group grow for a while before thinning it out too soon.

Check the food and humidity levels regularly without rearranging the entire setup. If you find mold, first remove the affected food dish and check the amount of food and the ventilation. A complete bedding change is usually unnecessary for a group that is otherwise stable.
