Bold, brilliant, and endlessly captivating — Trigoniulus coralinus, the Scarlet Millipede, is one of the most visually striking millipede species available in the invertebrate hobby. Native to tropical Southeast Asia and the Pacific, this compact species is cloaked in vivid coral-red to scarlet coloration that makes it look like a living jewel rippling across the substrate. A communal species that thrives in groups, the Scarlet Millipede is as easy to keep as it is beautiful to observe — an ideal species for both newcomers to the millipede hobby and experienced collectors seeking a vibrant, active display animal.

Why Choose Trigoniulus coralinus?

• Stunning Scarlet Coloration: Vivid coral-red to scarlet coloration across the entire body — one of the most brilliantly colored millipede species available in the hobby, instantly eye-catching in any enclosure
• Communal Species: Thrives in groups — a colony of Scarlet Millipedes moving through a bioactive enclosure is a genuinely spectacular display that improves with numbers
• Beginner-Friendly: Hardy, adaptable, and forgiving of minor husbandry variations — an excellent entry point into the millipede hobby for keepers of any experience level
• Active & Observable: Far more active and visible than many millipede species — frequently out in the open, making them a joy to observe throughout the day
• Bioactive Compatible: An excellent addition to bioactive enclosures as a cleanup crew species — they process leaf litter, decaying wood, and organic matter efficiently
• Compact & Display-Friendly: A small millipede reaching 3–5 cm — perfectly suited to detailed display enclosures where their vivid coloration can be appreciated up close
• Fast Reproducing: A prolific species that reproduces readily in captivity under good conditions — a self-sustaining colony is achievable with proper care

Natural History

Native to tropical Southeast Asia, northern Australia, and Pacific island regions, Trigoniulus coralinus inhabits humid tropical forest environments where it processes decaying organic matter in the leaf litter and soil layer. A detritivore by nature, this species plays an important ecological role as a decomposer, breaking down leaf litter, rotting wood, and organic debris into nutrient-rich material. The vivid scarlet coloration serves as aposematic warning coloration — advertising the presence of defensive secretions produced by the millipede’s ozopores when threatened. Despite this chemical defense, T. coralinus is entirely harmless to handle with clean, dry hands and poses no significant risk to keepers.

Handling & Defensive Secretions

⚠️ Defensive Secretions: Like all millipedes, Trigoniulus coralinus produces mild defensive secretions from its ozopores when stressed. These secretions are harmless to most people but can cause mild skin irritation in sensitive individuals and should not be rubbed into eyes or mucous membranes. Always wash hands thoroughly after handling. Avoid handling stressed or freshly disturbed specimens.

Care Requirements

• Enclosure: Well-ventilated enclosure with a secure lid; a 5–10 liter container is suitable for a small group, scale up for larger colonies
• Substrate: 3–5 inches of moist coco fiber mixed with leaf litter, rotting hardwood, and organic matter — the substrate is both habitat and food source
• Temperature: 75–84°F; consistent tropical warmth promotes activity and reproduction
• Humidity: 75–85%; keep substrate consistently moist but not waterlogged; provide good surface ventilation
• Diet: Decaying hardwood leaves (oak, magnolia, beech), rotting wood, leaf litter, and occasional fresh vegetables or fruit; calcium supplementation (cuttlebone) supports healthy exoskeleton development
• Groups: Best kept in groups of 6+ for optimal activity, display, and reproduction
