Armadillidium klugii “Montenegro”: Care Guide
Sep 27, 2026
Armadillidium klugii “Montenegro” stands out with its colourful markings. Its enclosure needs a balance: part of the surface can stay drier, but a moist retreat must always be available. Here is how to provide both without soaking the whole box.

Getting to know your isopods
Montenegro is a pill isopod and can roll up when disturbed. Several animals may gather beneath one piece of bark.
That is not unusual, but still offer more than one shelter so they can choose between moister and drier places.
Setting up the enclosure
Build your own setup
If you are choosing your own substrate and furnishings, our Assel Box with Quad Ventilation (11 L) provides the enclosure on its own. It measures 37 × 26 × 14 cm, is stackable and has four ventilation areas. Keep these clear on the shelf and fasten the lid on both sides.
Start with a set
Our Isopod Starter Set includes the same 11-litre enclosure, TropicSoil, sphagnum, feeding leaves/leaf mulch and cuttlebone pieces. An XL feeding dish and Mini insect drinker are included too. Cork and our isopod food are optional additions, not contents of this set.
Add substrate and leaf litter
Add several centimetres of loose, suitable substrate with decomposed leaves and white-rotted wood, then cover the surface with leaf litter. With the starter set, prepare the sphagnum according to its packaging and arrange the TropicSoil, leaves and moss to create a moist side and a less damp side.
Arrange shelters and a moist retreat
Our Cork Fragments 200 g provide cover. Choose suitable pieces and position them securely, leaving sheltered spaces underneath. Spread the shelters across different moisture levels and leave one corner accessible for watering.
A lotus seed pod for the isopod enclosure adds structure between existing shelters, with small nooks and another surface to explore. Choose openings wide enough for your animals and position it securely on the floor. Leaf litter and cork remain the basis of the setup.
Keep the feeding spot accessible
Position the feeding dish so you can remove it for cleaning without rearranging the shelters. Keep the drinker accessible too. Both are already included in the starter set, so you do not need an additional Carefree Bundle for this setup.
Distribute Montenegro’s cork across both areas: some on the drier side, some sheltering the moist corner. This lets the animals choose where to settle.
Managing temperature and moisture
Use 22–24 °C as a guide. Keep part of the floor relatively dry and one corner beneath leaves or moss consistently moist.
Check how quickly that corner loses moisture, especially in well-ventilated boxes. Water according to the substrate’s condition rather than on a fixed day each week.
Food, calcium and a practical feeding spot
Keep leaves, wood and calcium available
Leaf litter and white-rotted wood provide food as well as habitat. Replenish them as they are consumed and keep a calcium source such as cuttlebone available. Cuttlebone pieces are already included in the starter set.
Portioning our isopod food
Offer our Premium Sowbug Food in small portions with the included wooden spoon, either dry or lightly moistened. The plant-and-mineral mixture contains herbs, vegetable ingredients, brewer’s yeast and algae-derived calcium. Check what has been eaten before adding more, and remove leftovers before they spoil.
Choosing a feeding dish
Our Isopod dish provides a compact feeding spot. The Isopod double dish keeps food and minerals separate. Choose the Isopod dish XL when larger animals or more isopods need room around the food. A larger dish does not mean you need to fill it with a larger portion.
If Montenegro leaves a portion, remove it and offer less next time. The dish supplements the leaf-and-wood base rather than replacing it.
Choosing a dish and drinker together
Already have a furnished enclosure and want to add a feeding and watering station? The main difference between our Isopod Carefree Bundles is the dish:
- Isopod Carefree Bundle M: a standard isopod dish for a compact feeding spot.
- Isopod Carefree Bundle L: a double dish with two separate feeding areas.
- Isopod Carefree Bundle XL: an XL dish with more feeding space.
Each also includes a Mini insect drinker, a 30 ml bottle and three cotton pads. Enclosure, substrate and food are not included. Fill the drinker with water only, clean it regularly and replace the cotton pad.
Young isopods and a growing colony
Allow the group time to establish and leave its retreats largely undisturbed. Small juveniles may remain hidden in the substrate at first.
Replenish consumed leaves and keep the moist corner well covered. Add shelters or divide the colony as numbers increase.
To start another culture, you can furnish an additional Assel Box with Quad Ventilation (11 L) in the same way. Label each separate group with its full species or form name so that offspring remain easy to identify.
Your quick care check
- Check moisture beneath leaves and cork; the moist retreat must never dry out completely.
- Check the dish, remove leftovers and refill according to consumption. Keep the drinker and cotton pad clean.
- Replenish leaves, keep ventilation clear and provide more floor space and shelters as numbers increase.
Do not release isopods outdoors. Wash your hands after maintenance. Before adding them to a terrarium, check that its climate and inhabitants suit the species.
Choosing between isopods
Montenegro’s colourful pattern differs clearly from the stripes of zebra isopods. Compared with Armadillidium gestroi, more of its enclosure surface can remain drier.
That does not mean removing the moist corner. The basic setup remains similar: leaves, wood, cork and calcium.
Questions about care
Can I keep Montenegro completely dry?
No. Part of the floor can be drier, but a moist retreat must always remain accessible.
Why do they roll up when sprayed?
It is a defensive response. Add water gently to the moist area instead of spraying directly onto the animals.
What if they leave vegetables uneaten?
Remove leftovers and offer less next time. Plenty of suitable leaves and decaying wood remain the main food supply.
