Cubaris sp. "Shiro Utsuri"
An undescribed pill isopod from Taiwan, white with black markings whose extent varies a lot between individuals. Hardy and quick to settle.
Cubaris sp. 'Shiro Utsuri' is an undescribed pill isopod from Taiwan whose trade name is borrowed from koi keeping, where a shiro utsuri is a black fish broken up with clean white markings. The ground colour is a translucent white with black marks that range from heavy patches to a light scatter, so no two animals match. Adults sit at 15-20mm and stay out on the surface, which makes the markings easy to enjoy; it conglobates when startled and the contrast still shows on the curled body. Coming from subtropical Taiwan it wants more warmth and moisture than Mediterranean species, around 22-26C, with supplementary heat in a cold room over winter. Set up a humid gradient rather than a uniformly wet box, with good cross-ventilation to hold off mould. Give 5-8cm of living substrate built on flake soil with leaf litter and decaying hardwood, and keep a constant calcium source. It is hardy and settles quickly, breeds from roughly six to eight months old, and lives two to three years.

22-26C. Being subtropical it may need supplementary heat in winter. Dampen one end well and leave the far end drier.
5-8cm of living substrate: flake soil topped with leaf litter and decaying wood, with cork bark for cover. Keep cross-ventilation running.
Keep leaf litter and rotten wood available and add a little carrot or courgette and some protein weekly. Cuttlebone or crushed shell stays in permanently.
Harmless and placid, conglobating when startled. Kept in groups and happy alongside springtails and other isopods.
It likes humidity but must never be waterlogged. Note that sellers list it under either Nesodillo or Cubaris.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Shiro Utsuri Isopod is 22〜26℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Shiro Utsuri Isopod is 2-3 years. With proper care and nutrition, they can live a long and healthy life.
Shiro Utsuri Isopod typically reaches 15-20mm as an adult. Size may vary depending on care conditions and individual genetics.
Shiro Utsuri Isopod feeds on: Leaf litter and decaying wood as the base, with a little carrot or courgette and some protein each week, plus permanent cuttlebone or crushed shell. Aim for a balanced diet with appropriate feeding frequency.
