Cubaris sp. 'Ice Flower' Isopods

The first thing you notice about Cubaris sp. 'Ice Flower' is the frost. Across a single colony you get a soft, wintry mix of pale whites, creams and subtle blue-greys, and because the morph is colour-variable, no two individuals look quite the same. Some lean almost pure white, others carry a faint blue-grey wash, and a few settle somewhere in the cream middle. It is an understated, ethereal look rather than a bold one, and that is exactly why I keep coming back to it.

'Ice Flower' is a hobby trade name for an undescribed Cubaris, most likely of Thai limestone-cave origin like the other premium species in this group. These are small, dwarf-tier animals at around 10mm fully grown, so they sit naturally in a planted display without dominating it. They are mostly nocturnal and a little shy while they settle, hiding in the substrate for the first few weeks, but a mature colony becomes far more visible and will live happily together for two to three years. Like all Cubaris they conglobate, rolling into a tight defensive ball when disturbed, and the pale pastel body against a dark substrate makes that little rolled marble a lovely thing to watch.

If you are building a pale cluster, the Ice Flower sits beautifully next to the brighter white of the Snow Queen, and it is a gentler starting point than the more demanding Rubber Ducky or the high-contrast Panda King. If you have never kept the genus before, I would still point you toward Cubaris murina first, then come back to the Ice Flower once you have a colony ticking along.

Care follows standard Cubaris lines. They are cave-adapted animals that appreciate a little warmth, ideally around 21 to 26°C, and they want a humid gradient rather than a wet box. Keep one end damp at roughly 75 to 85% humidity and let the far end run drier, with good cross-ventilation so the air stays fresh instead of stagnant. Give them plenty of cover, cork bark, decaying wood and a few flat stones, and skip the water dish, since misting and a damp corner are all they need and standing water only invites mould. Moist, not wet, is the whole game, and overwetting is the quickest way to lose a colony.

Give them a deep, living substrate, around 10cm so they can burrow. I build a base of flake soil, rotted hardwood and topsoil rather than a plain coco-coir mix, which holds moisture without turning sour and feeds the colony as it breaks down. Work plenty of calcium and limestone through it for clean moults, cap the surface with leaf litter such as magnolia leaf litter and a few pieces of decaying wood, and add a springtail culture to keep mould down and the base ecosystem turning over.

They are a steady breeder rather than an explosive one. Given stable warmth, a proper gradient and enough calcium, a settled colony grows reliably, with females carrying young in a marsupium and releasing fully formed juveniles that pick up the frosty colouration as they moult through. They feed as detritivores on the leaf litter and rotting wood in the enclosure, topped up now and then with a little veg or a protein source such as fish flake, so most of their diet is simply the setup around them. It is slow, patient population growth, and I think that suits the animal.

Every order is captive-bred, boxed double-walled around a ventilated tub of damp sphagnum and posted Monday to Thursday by tracked next-day Royal Mail with a live-arrival guarantee and a small overcount as standard.
