Texas gold millipedes are the best native millipede for a first-time keeper, and one of the few you can buy captive bred rather than wild caught. Chicobolus spinigerus is a slim, glossy species banded in amber and dark brown, reaching around 4 inches. They need less depth than a giant African millipede, tolerate a wider temperature range, and are almost entirely undemanding provided the substrate is right. The catch, and it is the same one for every millipede, is that the substrate is the food. Get that wrong and nothing else you do matters.
Species Overview
Texas golds come from the southeastern United States, mostly Florida, Georgia, and the Gulf states, despite the common name pointing at Texas. Names in the hobby are loose, and this species is also sold as the Florida ivory millipede, which causes genuine confusion with the true ivory millipede, Chicobolus being the same genus in some listings and not in others.
They live in leaf litter and rotting wood on the forest floor, burrowing shallowly rather than deeply. That is the key difference from the giant African species: less digging, more surface browsing. The husbandry principles shared across the group are set out in general millipede keeping, and this species follows them with a shallower substrate.
Adults reach 3 to 4 inches with a slim cylindrical body, glossy dark brown segments edged in amber or gold, and dark red legs. They are detritivores, meaning they eat decaying plant matter, and they have no interest in live prey at all.
Like all millipedes they secrete a defensive fluid when stressed, containing benzoquinones. It is harmless on skin but stains, and it should be kept away from eyes. Wash your hands after handling.

Enclosure Setup
A 5 to 10 gallon tank or a 6 to 12 quart plastic bin suits two or three adults. Millipedes are unbothered by company and can be kept in small groups without any risk of aggression.
Substrate depth: 4 to 6 inches. Less than a giant African millipede needs, but still deep enough for the animal to bury completely and for a female to lay.
Substrate is the whole build. Millipedes eat their bedding, so the mix matters more than any other element:
- 3 parts crumbling rotten hardwood, ideally oak or maple, well decayed
- 2 parts coconut fibre or peat
- 1 part organic topsoil, no fertiliser or perlite
- A generous top layer of dry hardwood leaf litter
The rotten wood is not optional. A millipede kept on coco fibre alone will slowly starve while looking fine, and this is the single most common reason captive millipedes fail to thrive. Source wood from a hardwood log soft enough to crumble in your hand, away from roadsides and treated timber.
Leaf litter, thickly. Oak, magnolia, maple, or beech. Several inches deep and topped up as it disappears, because its disappearance is the animal eating.
Cover: a piece of cork bark laid flat and some larger chunks of decaying wood. They will spend daylight hours underneath.
Lid: solid with modest ventilation. Millipedes climb well and will find gaps, and the substrate needs to stay humid.
Temperature and Humidity
Room temperature works across a wide band, 68 to 78F, with no supplemental heat needed in a normally heated home. This tolerance is one of the species’ real advantages over tropical millipedes.
Humidity should sit at 70 to 80%. The way to achieve it is substrate moisture, not misting. Pour water into one section of the bin until that area is damp throughout, and let the rest stay merely moist. The substrate should hold together when squeezed without releasing water.
Two failure modes to avoid. A bin that dries out causes a millipede to bury and stop eating, and prolonged drying kills. A bin that is waterlogged goes anaerobic, smells sour, and produces mites and mold. The gradient is the safety margin, since the animal will place itself wherever suits it.
Check moisture weekly by digging a finger into a corner where nothing is buried.
Diet and Feeding
The substrate and leaf litter provide most of the diet. Feeding is supplementary and easy to overdo.
Calcium, always available. Cuttlebone, crushed eggshell, or crushed oyster shell on the surface. Millipedes need it for their exoskeleton and get through it visibly.
Vegetables, twice weekly at most. Cucumber, courgette, squash, sweet potato, carrot, and soft fruit in small amounts. Remove anything uneaten within 48 hours.
Occasional protein. A pinch of fish flake every few weeks. Optional, and easy to overdo.
Skip: citrus, anything salted, produce from a treated garden, and any wood or leaves from a conifer.
Add springtails at setup. They suppress mold in the damp section and compete for nothing the millipede wants. A small population of dwarf white isopods works alongside them, processing waste and leftover vegetables before mites establish, and the two together make a millipede bin close to self-maintaining.
Behaviour and Handling
Texas golds are among the easiest invertebrates to handle. They do not bite, they have no sting, and a millipede on your palm will simply walk. Keep the session short and low over a table, wash your hands afterwards because of the defensive secretion, and do not handle one that has coiled tightly, which is its stress response.
Expect most activity at night and after you dampen the substrate. During the day they are usually buried or under bark.
Normal behaviours worth recognising:
- Coiling into a flat spiral. Defensive, and a sign to leave it alone.
- Burying for days or weeks. Normal, and usually a molt.
- Surface wandering in daylight. Often a substrate problem, either too dry or too wet.
Molting
Millipedes molt in an underground chamber they construct themselves, and they add body segments and legs with each molt rather than simply growing larger. A juvenile gains segments through successive molts until it reaches its adult count.
A molting millipede stays buried for one to several weeks and is soft and vulnerable throughout. Do not dig, do not disturb the bin, and do not go looking for it. They also frequently eat the shed exoskeleton for its calcium, so leave anything you find in place.
Because molts happen out of sight and weeks apart, they are easy to lose track of, particularly with several animals in one bin. Logging what you observe in InvertMate, our free invertebrate care app gives you a record of when each animal was last seen on the surface, which is the practical way to distinguish a normal molt from a problem.
Breeding
Texas golds breed readily in a well established bin, which is why captive bred stock is actually available for this species.
Conditions do the work. Deep substrate with plenty of rotting wood, consistent humidity, constant calcium, and a group of at least three or four animals so both sexes are present. Sexing is possible by examining the seventh body segment, where males have modified legs called gonopods in place of a normal leg pair, though it takes a careful look.
Females lay eggs in a small chamber in the substrate. Hatching takes several weeks, and the young emerge tiny with few segments and legs, adding both as they molt. They are easy to miss entirely until they are several months old.
Do not sift the substrate looking for eggs or juveniles. The most common cause of breeding failure is a keeper disturbing the bin.
If you want a larger species after this one, our guides to giant African millipede care and the arid-adapted desert millipede cover two very different alternatives.
Common Problems
Mites. Small pale specks around the legs and segments. A light load is normal and harmless. A heavy load usually follows overfeeding on vegetables, so cut back and rehouse into fresh substrate if it persists.
Refusing food and staying buried. Usually a molt. Leave it alone.
Surface wandering constantly. Substrate too dry, too wet, or exhausted. Check moisture first, then whether the rotten wood has been consumed.
Sour smelling bin. Waterlogged and anaerobic. Increase ventilation and let it dry back.
Not growing. Insufficient rotting hardwood in the mix. This is the commonest underlying problem in millipede keeping.
Death shortly after purchase. Often a wild caught animal of unknown age, or shipping stress. Captive bred stock is worth seeking out for this species specifically.
FAQ
How long do Texas gold millipedes live?
Five to seven years in captivity, which is typical for a mid-sized native species and longer than most keepers expect. Lifespans across the group vary considerably, as covered in our guide to how long millipedes live.
Are Texas gold millipedes good for beginners?
Yes, one of the best choices. They tolerate a wide temperature range, need no heating, do not bite or sting, and handle calmly. The only strict requirement is plenty of decaying hardwood in the substrate, since that is their food.
What do Texas gold millipedes eat?
Decaying hardwood and leaf litter as the staple, supplemented with a constant calcium source and small amounts of vegetables twice weekly. They are detritivores and take no live prey. Overfeeding vegetables is the main cause of mite problems.
Do Texas gold millipedes bite?
No. They have no biting mouthparts capable of harming a person and no sting. When stressed they coil up and may release a staining defensive fluid, which is harmless on skin but should be kept away from the eyes.
Can Texas gold millipedes live together?
Yes. They are not territorial and are commonly kept in groups, which is also necessary for breeding. Three or four animals in a 10 gallon tank works well, provided the substrate is deep and food is plentiful.
Are Texas gold millipedes the same as ivory millipedes?
Not quite, and trade names are inconsistent. Chicobolus spinigerus is sold as both Texas gold and Florida ivory, while the name ivory millipede is also applied to other species. Buy on photographs and scientific name rather than the common name.
How is a millipede different from a centipede?
Millipedes have two pairs of legs per segment, eat decaying plant matter, and are harmless. Centipedes have one pair per segment, hunt live prey, and can deliver a painful bite. The full comparison is in our guide to millipedes and centipedes.
