Armadillidium nasatum 'Dalmatian' is a charming and distinctive European isopod that combines two genuinely appealing features: the bold spotted "Dalmatian" pattern and the species' famous elongated "nose." A. nasatum is commonly known as the Long-nosed or Nosy Pill Woodlouse for its prominent forward-projecting snout (a distinctive scutellum), which sets it apart from almost every other Armadillidium. The Dalmatian morph adds scattered dark spots and patches — usually black, sometimes brown — over a pale grey-cream base, often with the species' characteristic light banding, creating a genuinely eye-catching, dappled look. For keepers who want a hardy, easy isopod with real character and a distinctive spotted pattern, the nasatum Dalmatian is a delight.

What makes the nasatum Dalmatian particularly worth keeping is the combination of that distinctive appearance with genuinely easy, forgiving, beginner-friendly care. They're hardy, prolific, and quick to establish — and notably cool-tolerant, even suitable for outdoor or unheated setups, which makes them especially well-suited to UK keeping. They're true pill bugs, conglobating into a tight ball when disturbed, and share the reliable, accessible husbandry that makes Armadillidium the most beginner-friendly isopods in the hobby. They sit alongside easy, colourful Armadillidium like the Zebra, Magic Potion, and T+ Albino.

They're a European species — found across Western and Southern Europe, and well-naturalised in Britain — which makes them genuinely hardy and adaptable in UK conditions, tolerating cooler temperatures that many tropical isopods can't. As a temperate species they prefer moderate humidity with a gradient and good ventilation, and they're notably forgiving of a wide range of conditions.

What Makes Nasatum Dalmatian Isopods Special

Several factors make the nasatum Dalmatian a genuinely appealing isopod:

The distinctive "nose." The standout structural feature of A. nasatum is its prominent, forward-projecting snout (scutellum) — the reason it's called the Long-nosed or Nosy Pill Woodlouse. It's a genuinely unusual and characterful feature that distinguishes it from virtually every other Armadillidium, and a real talking point.

The bold Dalmatian spotting. The Dalmatian morph scatters dark spots and patches — usually black, occasionally brown — over a pale grey-cream base, often with the species' characteristic light banding. The dappled pattern varies between individuals, giving a colony genuine visual interest and that eye-catching "Dalmatian" look.

Genuinely easy and prolific. They're hardy, adaptable, and quick to establish, breeding readily to build a self-sustaining colony. This makes them ideal for beginners, satisfying for keepers who enjoy watching colony growth, and dependable as a bioactive cleanup crew.

Cool-tolerant and UK-friendly. As a European species naturalised in Britain, the nasatum Dalmatian tolerates cooler temperatures far better than tropical isopods — even suitable for outdoor or unheated enclosures. This makes them genuinely easy and reliable to keep in UK homes without supplemental heating.

Adaptable and forgiving. They tolerate a notably wide range of humidity (45–80%) and conditions, making them one of the more forgiving isopods for newcomers still finding their feet with husbandry.

Conglobation. Like all Armadillidium, they roll into a tight defensive ball when disturbed — the classic roly-poly behaviour, here on a characterful long-nosed, spotted isopod.

How Nasatum Dalmatian Compares to Other Armadillidium

If you're choosing between easy, distinctive Armadillidium, here's how the nasatum Dalmatian fits in:

  • vs Zebra (A. maculatum): Both are hardy, beginner-friendly patterned Armadillidium (and confusingly, Zebras are sometimes also called "Dalmatian"). Zebras show bold black-and-white stripes; the nasatum Dalmatian shows scattered spots plus its distinctive nose. Different species, different patterns — both easy and rewarding.
  • vs Magic Potion (A. vulgare): Both are easy, colourful Armadillidium morphs. Magic Potion shows pale semi-transparent tones with yellow markings; the nasatum Dalmatian is spotted with its long nose. Both beginner-friendly — choose based on whether the pale potion look or the spotted long-nosed look appeals.
  • vs T+ Albino (A. vulgare): Both are easy, hardy Armadillidium morphs. The T+ Albino glows warm orange-gold; the nasatum Dalmatian is dark-spotted on pale with its distinctive nose. Different looks from the easy Armadillidium range.
  • vs Yellow Spanish Granulatum (A. granulatum): Granulatum are larger, bumpy, and yellow-spotted; the nasatum Dalmatian is smooth, black-spotted, and long-nosed. Both hardy Mediterranean/European species with similar care — different textures and patterns.

Setting Up the Enclosure

A 10–15 litre plastic container or terrarium suits a starter colony — these are sociable isopods that don't need vast space, and they grow well in groups. Plastic tubs with clip-lock lids hold appropriate humidity while allowing the ventilation Armadillidium need. The 3L Braplast tub works for smaller starter colonies, with larger housing as the prolific population grows.

For ventilation, drill holes on opposite sides of the container for cross-ventilation. Medium ventilation suits them — enough airflow to prevent stagnant, overly-humid conditions while maintaining the moist zone of a gradient. Provide plenty of hiding spots with cork bark, leaf litter, and bark pieces. Keep the enclosure out of direct sunlight. As a cool-tolerant species, they don't need a warm spot — a normal room (or even a cool one) suits them. Browse our accessories collection for appropriate enclosures, vents, and other essentials.

Substrate

Build a straightforward substrate appropriate for this hardy European species:

  • Organic topsoil base (pesticide-free) as the foundation
  • Sphagnum peat moss mixed throughout for moisture retention
  • Crushed limestone, oyster shell, or eggshells distributed throughout for calcium
  • Flake soil mixed in for added nutrition
  • Pieces of rotting white wood incorporated throughout (genuinely favoured)
  • Forest moss for humidity and grazing

Substrate depth: 5–8 cm for burrowing — they appreciate enough depth for moulting and security.

Top layer: Generous hardwood leaf litter — magnolia leaves and oak leaves work particularly well for long-lasting cover and food. Add cork bark, rotting white wood, and forest moss, plus a sphagnum moss patch on one side to create the moist zone of the gradient (around ⅓ of the enclosure moist).

Humidity and Temperature

Maintain a moisture gradient — keep around ⅓ of the enclosure moist with forest moss, rotting white wood, and damp leaf litter, while the rest stays drier. A. nasatum are notably adaptable, tolerating a wide humidity range (45–80%), so a gradient lets the colony self-regulate comfortably. Good ventilation prevents stagnation.

As one PostPods customer noted about following the website's care guidance, getting moisture right is the key to keeping isopods successfully — even with a forgiving species, a proper gradient beats a uniformly wet enclosure. When in doubt, provide the gradient and let them choose.

Temperature should be 15–28°C — and notably, the nasatum Dalmatian is cool-tolerant, comfortable at cooler room temperatures and even suitable for outdoor or unheated setups. This makes it genuinely easy to keep in most UK homes without supplemental heating. It tolerates warmth within range too, but avoid sustained extremes.

Diet

Nasatum Dalmatian isopods are unfussy detritivores that enjoy a slightly higher-protein diet than some:

  • Primary diet (always available): Hardwood leaf litter (oak, beech), decaying rotting white wood, forest moss, lichen, dried plant matter
  • Vegetables (1–2x weekly): Carrot, courgette, sweet potato, greens. Replace within 24–48 hours.
  • Fruit (occasionally): Apple, banana — small amounts
  • Protein (at least 2x weekly): Fish flakes, dried shrimp, dried daphnia. They genuinely enjoy a slightly higher-protein diet, which supports their prolific breeding. They'll also consume shed invertebrate and reptile moults. Browse our accessories collection for the full range of protein supplements.
  • Calcium (essential — always available): Cuttlefish bone, crushed limestone, oyster shell, eggshells. Essential for healthy moulting — provide multiple sources distributed throughout.

Feeding approach: Maintain a base of leaf litter and rotting white wood, supplementing with vegetables, occasional fruit, regular protein, and a constant calcium source. Remove uneaten fresh foods within 24–48 hours to prevent mould.

Breeding

Nasatum Dalmatian isopods are prolific and easy breeders, quick to establish a self-sustaining colony — one of their genuine appeals.

Breeding basics:

  • They reproduce sexually — males and females mate, and females carry fertilised eggs in a marsupium (brood pouch)
  • Live mancae emerge as fully-formed miniature versions of adults
  • They establish quickly and build colonies readily
  • The Dalmatian spotting develops as juveniles mature; a pure colony breeds the morph reliably (you may occasionally see brown-spotted individuals alongside the black-spotted)

For breeding success:

  • Stable temperatures within range (18–24°C is ideal, though they tolerate cooler)
  • A proper moisture gradient (⅓ moist)
  • Adequate calcium for breeding females
  • Regular protein supplementation (they breed especially well with good protein)
  • Plenty of cover and rotting white wood

As a prolific, easy breeder, the nasatum Dalmatian rewards keepers with quick, steady colony growth — genuinely satisfying, and forgiving of the occasional beginner mistake.

Pair With Springtails

Add a thriving springtail culture to any nasatum Dalmatian setup. Springtails handle mould and microbial growth at a scale isopods can't manage — particularly useful around protein foods and in the moist zone of the moisture gradient. They coexist peacefully with the nasatum Dalmatian and form a helpful cleanup partnership.

Who Should Buy Nasatum Dalmatian Isopods?

Ideal for:

  • Beginners wanting an easy, hardy, characterful first isopod
  • Keepers who love the distinctive "nose" and bold spotted pattern
  • Cooler homes, unheated rooms, or outdoor setups (they're cool-tolerant)
  • Bioactive setup builders wanting a hardy, prolific cleanup crew
  • Collectors building an easy or distinctive Armadillidium collection
  • Anyone wanting a reliable, fast-establishing self-sustaining colony

Not ideal for:

  • Keepers wanting large, bold display isopods (these are medium-sized)
  • High-humidity tropical setups (they prefer a moderate gradient)
  • Heavily-planted bioactive setups where plant-nibbling is a concern (Armadillidium enjoy plants)
  • Anyone wanting non-rolling fast surface species (these are rolling pill bugs)

Realistic Expectations

The nose and spots are the appeal. Set expectations toward the distinctive long-nosed profile and the dappled Dalmatian spotting rather than bright colour — that characterful combination is precisely what makes them special. Spotting varies between individuals and develops as they mature.

They're genuinely easy and forgiving. As a hardy, adaptable European species, the nasatum Dalmatian tolerates a wide range of conditions and won't punish minor husbandry mistakes — one of the best characterful first isopods.

They're cool-tolerant. Unlike warmth-loving tropical species, they're happy at cooler room temperatures and even in unheated or outdoor setups — genuinely well-suited to UK homes.

They can't be kept bone dry, but tolerate a wide range. While adaptable across 45–80% humidity, they still need a moist zone in their gradient — provide the damp retreat and good ventilation.

Expect prolific, quick breeding. As an easy, fast-establishing breeder, colonies build steadily and reliably — genuinely satisfying, and quick to become a self-sustaining cleanup crew or display colony.

Building Your Setup

A complete nasatum Dalmatian setup needs basic substrate components, abundant calcium-rich materials, generous leaf litter and bark, rotting white wood, and regular protein. Browse our accessories collection for everything you need — enclosures, ventilation, leaf litter, calcium (cuttlebone, limestone, oyster shell), and protein supplements.

The Perfect Sheets To Lie On While Writing Amazon Reviews
Size: Full, Color: Light Gray
As I write this, I am laying on an adjustable full sized bed by Hofish and a 10.5" comfort foam mattress by Classic Brands. I know I sound like I am an Amazon plant, but I swear I am not. I'm not even a stockholder anymore. This is the most awesome bed stylings combination I have had in many, many years. In fact, it is the best I have ever owned and it is beat only by some ritzy resort I stayed at on vacation like 20 years ago, though I admit I was pretty drunk the entire time so my memory might not be the most accurate. But getting back to today... these sheets are great. I washed them twice - I'm not a neat freak, I am just amazingly disorganized and easily distracted while doing laundry, so tonight they went though two wash cycles and one dry. And then I put them on the bed. While these sheets are not deep pocket sheets, they don't need to be with this mattress. There is enough room and border for them to tuck and wrap with the elastic to give a strong grip under the mattress, which is important as the adjustable frame continually put the sheets and mattress though its repeated adjustable calesthenics-type positioning. The other two sheet sets I have used since I got this bed have struggled poorly with this. In the day or so and at least a dozen position changes, these sheets stay in place with no popped corners to exposing the bowl as the head and feet rise. Of course, till will tell if it lasts, but so far they are the best of the batch of sheets in my closet. As for texture, they are awesome. I'm a dude. I don't really know what thread count or knit or whatever really means. But these sheets feel like a well-washed favorite, quality rock & roll concert t-shirt. And not one of these glitter puff stupid new groups, like a real rock band from the 80s that now charges $250 for a concert ticket and $60 for a t-shirt...but that group you saw back then, paid $10 for the shirt and you STILL have it and love to wear it because it is perfectly molded to your body, soft and reliable. The kind of shirt you will wear under your suit at work and just grin not just for mental middle finger to corporate dress codes, but because the t-shirt is just that great of a feeling. Well, that is what these sheets feel like. And now you get to sleep in it. It is that awesome. In LA right now we are having a nasty heat wave, but these sheets don't seem to bake me even with my stuttering AC. The flannel sheets I love seem to trigger the butt sweats as soon as I lay down in this heat, but no such problem with these. So really, I'm absolutely happy with these things. I am going to order more in other colors as soon as Amazon gets them back in stock. Great price, great quality, great comfort, great fit, great deal. It is that simple.

Soft smooth and wrinkle free!
Size: King, Color: White
The most comfortable sheets I’ve had in years! Soft and don’t wrinkle up in the bed. Some reviews said they are thin but I think they’re perfect! I don’t want super thick sheets as we are hot sleepers. These are the perfect feel. They also stretch very well to fit on my mattress all the way around and I have a thick mattress! My precious sheets were a struggle to get over the corners but these fit perfectly. Would buy 10 times over! Such a good value as well!

Soft Material, but Color Not as Expected
Size: Queen, Color: Oatmeal, Size: Queen, Color: Oatmeal
I did not open or use this sheet set because the color wasn’t suitable for the occasion I intended. I prefer to return items in unused condition so they can be resold as new, so I cannot comment on the exact fit. From a price point, it's value for money. From touching the fabric through the packaging, the material feels soft and of fair quality. There is no unpleasant smell, and the overall functionality seems fine based on its construction. My only disappointment is the oatmeal color—it looks somewhat dull and gives off an aged or slightly used appearance. I was hoping for a brighter, creamier tone. Aside from the color issue, the product appears to be well made and comfortable, which is why I’m giving it four stars.

Nice and soft
Size: Queen, Color: Chambray
Update: I’m very happy with this sheet set! I’m currently only using the fitted sheet as I don’t have a need for the top sheet or pillow cases right now. It hasn’t popped off the mattress at all like the previous cheep sheet I had. Original post: The sheet set arrived today. Haven’t actually tried it yet because I need to wash it first. From I can see, looks great. Once it’s washed and on my bed, and can figure out how to update my review I will do so accordingly. It’s soft like most people have said and the color is nice, though they didn’t have my favorite color purple in a shade I like so I got the ‘fancy blue’ (don’t remember the actual name of the color) because I desperately needed a new sheet of quality.

Very comfy sheets, nice fabric
Size: Full, Color: Oatmeal
I wasn’t expecting such good quality forthis price. They’re very soft, but of fairly thick fabric. I’m sleeping great on them. The pockets are deep enough for an 8” foam mattress plus my 3” topper. Will be getting another set for the second bedroom.
