Cubaris sp. "Red Edge"
An undescribed pill isopod from the limestone caves of Thailand. Every segment of the dark blue-grey to near-black body is framed in bright red from head to tail. Bold for a cave Cubaris and comparatively easy to keep.
Cubaris sp. 'Red Edge' is an undescribed pill isopod from the limestone cave systems of Thailand and one of the most enduringly popular lines in the hobby. The body runs dark blue-grey to near-black and every segment is framed by a band of bright red that traces the whole outline from head to tail. That is bold enough to read from across a room, which is unusual among cave Cubaris, most of which lean muted. The warmer Red Edge Orange and the pale Red Edge Blonde were both drawn from this stock. Give a deep living substrate of flake soil blended with rotted hardwood and a little topsoil, and keep a plain coco coir base out of the mix since it feeds them nothing. Cross-ventilation matters as much as moisture, so keep air moving without drying the tub out. Leave calcium within reach at all times and lay down leaf litter with cork bark or limestone for cover. Breeding is steady rather than explosive, with small broods arriving dependably in a mature, undisturbed enclosure.

The ideal temperature for the Red Edge Isopod is 22〜26℃. Ideal humidity is 75〜85%.
Care follows the familiar Thai cave template: 22-26C and around 75-85% humidity, with one damp end and one drier end so the colony can choose.

Leaf litter and rotten wood as the base, with small amounts of vegetable and protein, plus permanent crushed limestone or cuttlebone
22-26C and 75-85% humidity. Build a gradient with one damp end and one drier end, misting lightly two or three times a week.
Deep substrate of flake soil blended with rotted wood and topsoil; do not base it on coco coir. Add cork bark and limestone pieces for cover.
Leaf litter and rotten wood are the staples. Add small amounts of vegetable and protein, and keep crushed limestone or cuttlebone permanently available.
Harmless to people and conglobates when startled. Kept in groups, picking its way slowly across the leaf litter.
Breeding is slow, so leave the colony undisturbed rather than digging after it. A springtail culture keeps mould in check.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Red Edge Isopod is 22〜26℃. Recommended humidity is 75〜85%. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Red Edge Isopod is 2-3 years. With proper care and nutrition, they can live a long and healthy life.
Red Edge Isopod feeds on: Leaf litter and rotten wood as the base, with small amounts of vegetable and protein, plus permanent crushed limestone or cuttlebone. Aim for a balanced diet with appropriate feeding frequency.
