Species description
Geographical Origin and Habitat: Armadillidium klugii 'Slano' is a geographic variant or specific locality of the clown isopod, native to the coast of Croatia, particularly the area surrounding the coastal town of Slano in southern Dalmatia. In its natural habitat, it lives in Mediterranean environments characterized by a warm-temperate climate, populating leaf litter, crevices between limestone rocks, the base of dry stone walls, and damp soil patches.
Taxonomy and Genetics: This species belongs to the family Armadillidiidae and is a terrestrial isopodic crustacean. The 'Slano' designation identifies a stable geographic population displaying unique coloration traits compared to other Armadillidium klugii localities. It possesses the classic ability to undergo conglobation (rolling into a tight, almost perfect sphere) as a defensive behavior against potential predators.
Behavior and Habits: It is a detritivorous and scavenging species, extremely peaceful and active primarily during the night or in dim conditions. It spends daylight hours hiding under pieces of bark, leaves, or rocks where moisture levels are most stable. It is a highly social animal that forms large, breeding colonies. It is ideal as a clean-up crew (CUC) in bioactive terrarium setups.
Morphology: The coloration is beautiful: it features a dark grey-black base color decorated with three longitudinal rows of light spots (the central row is typically yellow or gold, while the outer rows are white). The outer margin of the carapace exhibits a prominent reddish-brown or orange border, creating a sharp visual contrast. There is no obvious sexual dimorphism, except for slight size differences.
Care, breeding and tankmates
Terrarium Setup: Housing requires a small plastic or glass enclosure (faunabox or terrarium) of at least 10-15 liters for a starting colony. The substrate must be at least 5-8 cm deep, consisting of an organic mix of peat moss, coco coir, crushed oak or beech leaves, and decaying wood. It is crucial to add a top layer of whole dry leaves and pieces of cork bark to provide shelter and foraging options.
Lighting and Heating: It does not require complex lighting or heating systems. The ideal breeding temperature ranges between 20 and 25 °C, and it can tolerate brief winter drops down to 15 °C. Avoid placing the enclosure in direct sunlight or near heat sources to prevent overheating. Ambient room light or a low-intensity LED strip to simulate a day-night cycle is more than sufficient.
Humidity and Hydration: Humidity must be managed by creating a moisture gradient within the enclosure. Keep approximately one-third of the substrate damp by placing wet sphagnum moss on that side, while leaving the remaining two-thirds dry. This allows the isopods to self-regulate their hydration by moving between zones. Mist the damp area once or twice a week with dechlorinated water.
Feeding and Supplementation: Feeding is straightforward, as their primary diet consists of the leaf litter and rotting wood in the substrate. Supplement this weekly with protein sources (fish flakes, dried gammarus) and fresh vegetables (carrots, zucchini). A constant source of calcium, such as cuttlebone or powdered eggshells, is absolutely mandatory to support healthy carapace development and successful molting.
Compatibility: This is an extremely peaceful species that coexists well with conspecifics of all ages. It can be housed with other calm invertebrates or used as a clean-up crew in enclosures with small, non-predatory reptiles or amphibians. Avoid co-housing them with aggressive, fast-reproducing isopod species (like Porcellio scaber) that might outcompete them for resources.
Health and Common Diseases: Primary risks include desiccation if the substrate dries out completely, or excessive stagnant moisture which can lead to mold outbreaks and grain mite infestations. A lack of calcium will lead to failed molts and high mortality in juveniles. Remove uneaten fresh food within 24 hours to prevent pest issues. No veterinary care is required.

The catalog's scalar value is 2.1 cm. The Schmalfuss (2013) — revision of the Armadillidium klugii group source reports a maximum adult measurement of 2.1 cm for this species, recorded as the dataset's reported length dimension. The biological datum refers to the base species Armadillidium klugii, not exclusively to the commercial variety. These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
