Cubaris sp. 'Red Edge Peach' is a warm-toned colour phase of the popular Red Edge isopod — displaying soft peach, pink, and coral body tones in place of the standard grey-brown, while retaining the characteristic red "skirts" or edges that give the species its name. The result is a genuinely lovely warm-toned Cubaris: peachy-cream to coral-pink across the body, rimmed with that signature red edging. For keepers who find the standard grey Red Edge a little plain, the Peach phase adds real warmth and visual appeal without changing the easygoing nature that makes Red Edge such a popular species.

Originating from Thailand, Red Edge isopods are widely considered one of the more accessible and forgiving Cubaris species — hardy enough to tolerate the occasional minor care slip while still offering that distinctive Cubaris look and the satisfying "duck face" profile. That combination makes them a sensible stepping stone for keepers who've mastered basic isopod care and want to move into more exotic Cubaris territory before tackling the most demanding species like Rubber Duckies. The Peach is simply the warm-toned version of that same approachable animal.

The Red Edge comes in several colour phases, and they make a natural collector's set: the standard Red Edge (grey-brown), the pale Red Edge Blonde, an orange phase, and this Peach. Like all Cubaris, they conglobate (roll into a tight defensive ball) when disturbed. Browse the full Cubaris collection to compare options.

What Makes Red Edge Peach Isopods Special

Several factors make the Red Edge Peach a genuinely appealing Cubaris:

The warm peach colouration. This is the headline. Soft peach, pink, and coral tones across the body — a real departure from the standard grey-brown Red Edge — finished with the signature red edging rimming each segment. The warm palette is the whole appeal of the Peach phase, and many keepers strongly prefer it to the standard variety.

One of the more forgiving Cubaris. Red Edge isopods have a well-earned reputation as one of the better "starter" Cubaris — hardier and less delicate than many premium species, with enough tolerance for minor care imperfections to give a learning keeper some margin for error. That accessibility carries straight through to the Peach phase.

More active than most Cubaris. A genuine plus — Red Edge isopods are notably more active and visible than many of their reclusive premium cousins. While still primarily nocturnal, they're frequently out exploring, which makes them a far more rewarding display species than the Cubaris that spend their lives hidden.

A natural stepping stone. For keepers who've succeeded with hardy beginner species and want to move into Cubaris, the Red Edge (in any colour phase) is the sensible bridge — offering the Cubaris experience without the unforgiving fragility of the most demanding species.

The signature red edging. Across every colour phase, the red "skirts" rimming each body segment are the defining Red Edge feature — and they look particularly striking set against the warm peach base of this phase.

Conglobation. Like all Cubaris, they roll into a tight defensive ball when disturbed — the classic rounded charm, here on a warm-toned, red-rimmed body.

How Red Edge Peach Compares to Other Red Edge Phases and Cubaris

If you're choosing between Red Edge phases or accessible Cubaris, here's how the Peach fits in:

• vs Standard Red Edge: Same species, different colour. The standard shows the classic grey-brown body with red edging; the Peach replaces the grey-brown with warm peach and coral tones while keeping the red edges. Identical care — choose by colour preference, or keep both.
• vs Red Edge Blonde: Both are warm-toned Red Edge phases. The Blonde is the paler, lighter variant; the Peach leans into warmer peach-and-coral tones. Natural companions in a Red Edge colour-phase collection.
• vs Miyako (Japanese Red Edge): Worth clarifying, because the names get conflated. The Thai Red Edge (this species) and the Japanese "Miyako" / Cubaris iriomotensis are often both called "Red Edge" in the hobby, but they're generally treated as distinct animals from different regions. The taxonomy of both is genuinely muddled — "iriomotensis" is widely regarded as questionable — so the names get used loosely. If you want the Japanese version specifically, see the Miyako listing.
• vs Rubber Ducky: The Red Edge is the accessible stepping stone; the Rubber Ducky is the more demanding premium species many keepers graduate toward. Master Red Edge care first, then step up.

Setting Up the Enclosure

A 6-litre container works well for a starter colony, with larger enclosures of 12 litres or more suiting established groups. Red Edge isopods appreciate consistent humidity, so aim for a setup that holds moisture while allowing medium ventilation — enough airflow to prevent stagnation and mould without drying out the enclosure.

Provide plenty of hiding spots — cork bark is essential, and they particularly appreciate mossy retreats and multiple hiding options. The warm peach colouration shows particularly beautifully against darker, naturalistic substrate. Keep the enclosure out of direct sunlight. Browse our accessories collection for appropriate enclosures, vents, and other essentials.

Substrate

Use a soil-based mix that retains moisture and provides calcium:

• Organic topsoil (pesticide-free) as the base
• Sphagnum moss patches for the moist section and moisture retention
• Flake soil for added nutrition and structure
• Rotting white wood pieces (important for nutrition)
• Leaf litter mixed through and on the surface
• Crushed limestone, oyster shell, or eggshells worked throughout for calcium

We recommend a topsoil and sphagnum-based mix rather than coco coir. Substrate depth: 5–8 cm for burrowing and security.

Top layer: Generous hardwood leaf litter — magnolia leaves, oak, birch, and maple all work well for long-lasting cover. Add cork bark and a sphagnum moss patch on the moist side. They genuinely appreciate mossy retreats.

Humidity and Temperature

Maintain humidity around 60–80% with a moisture gradient — keep approximately one-third of the enclosure consistently moist using sphagnum moss, while the rest stays drier with leaf litter and bark cover. Red Edge isopods like mossy retreats and will use the moist zone when they need it. Medium ventilation prevents stagnation and mould while retaining enough humidity.

As one PostPods customer noted about following the website's care guidance for Cubaris-type isopods, getting moisture right is the key to keeping them successfully — too much moisture is the most common avoidable mistake. While Red Edge isopods are more forgiving than many premium Cubaris, they still do best with a proper gradient rather than uniform wet conditions.

Temperature should be 23–26°C — they're tropical isopods that prefer consistent warmth. Room temperature in heated UK homes generally works well; avoid fluctuations and don't place the enclosure near heat sources or windows.

Diet

Red Edge isopods benefit from a slightly higher-protein diet than some other isopod species:

• Leaf litter (always available): Oak, birch, maple, and other hardwood leaves form the foundation of their diet
• Decaying wood: Particularly white-rotted softwood — an essential nutrition source; include pieces in the enclosure
• Vegetables (1–2x weekly): Sweet potato, carrot, pumpkin, squash are readily accepted. Replace within 24–48 hours.
• Protein (twice weekly — particularly important for this species): Fish flakes, freeze-dried shrimp, or dried bloodworms. Browse our accessories collection for the full range of protein supplements.
• Calcium (essential — always available): Cuttlefish bone, limestone, or crushed oyster shell supports healthy moulting — provide a constant source.

Feeding approach: Keep leaf litter and decaying wood available at all times as the dietary base, supplementing with vegetables, regular protein (more than most species), and a constant calcium source. Remove uneaten fresh foods within 24–48 hours to prevent mould.

Behaviour

Red Edge isopods are notably more active than many other Cubaris species. While still primarily nocturnal — hiding under cover during the day — they're frequently visible exploring their environment compared to shyer premium species. This makes them a far better "display" Cubaris: you'll actually see them out and about from time to time, rather than wondering whether they're still alive in there.

Their combination of activity, relative hardiness, and warm colouration makes the Red Edge Peach genuinely engaging to watch — more so than many of the rarer, more reclusive Cubaris varieties. Like all Cubaris, they roll into a ball when threatened.

Breeding

Once established, Red Edge isopods breed at a moderate rate. Broods tend to be on the smaller side compared to prolific species like Porcellio scaber, but they reproduce reliably under good conditions.

They're not the fastest breeders, so patience is needed when establishing a colony. Stable conditions — consistent temperature, humidity, and food supply — matter far more than any specific breeding triggers.

For breeding success:

• Stable temperature (23–26°C)
• A proper moisture gradient (one-third moist)
• Regular protein supplementation (important for this species)
• Plenty of calcium for breeding females
• Abundant cork bark and mossy hides
• A larger starter group establishes faster and provides genetic diversity

The Peach phase breeds the warm colouration reliably within a pure colony, with normal individual variation — some specimens showing more vivid peach-coral tones than others.

Pair With Springtails

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

Who Should Buy Red Edge Peach Isopods?

Ideal for:

• Keepers who've succeeded with hardy beginner species (like Porcellio scaber or Armadillidium vulgare) and want to try Cubaris
• Those wanting a more active, visible Cubaris species
• Keepers building experience before attempting more demanding species like Rubber Duckies
• Anyone who prefers warm peach and coral tones over the standard grey-brown Red Edge
• Collectors building a Red Edge colour-phase set (standard, Blonde, Peach)

Not ideal for:

• Complete beginners to isopods — start with a hardy Porcellio or Armadillidium first
• Keepers who tend to overwater (even forgiving Cubaris dislike waterlogged conditions)
• Those wanting a fast-breeding cleanup crew (broods are moderate-sized)

Realistic Expectations

The peach colouration varies between individuals. Set expectations toward a range from subtle peachy-cream to more vivid coral-pink — not every specimen will be identically vivid, and individual variation is completely normal. The signature red edging is consistent across the colony.

They're forgiving, but not invincible. Among the more tolerant Cubaris, with a margin for error while you learn — but they're still Cubaris, and they reward proper care rather than neglect.

They're more visible than most Cubaris. A genuine plus — you'll actually see these out exploring, unlike many of the reclusive premium species.

Breeding is moderate, not explosive. Broods are smaller than prolific species, and colonies build steadily rather than rapidly. Patience pays off.

The taxonomy is genuinely uncertain. Red Edge isopods carry several names and their classification is unsettled — part of the broader taxonomic messiness across the Cubaris genus. The animal itself is well-understood in keeping terms even where the naming isn't.

Building Your Setup

A complete Red Edge Peach setup needs a humidity-retentive soil-based substrate, abundant calcium, generous leaf litter, plenty of cork bark and mossy hides, and regular protein supplements. Browse our accessories collection for everything you need — enclosures, ventilation, leaf litter, calcium (cuttlebone, limestone, oyster shell), and protein supplements.
