Cubaris Isopods for Sale

Cubaris is the genus that changed the isopod hobby. When the Rubber Ducky was discovered in Thai limestone caves in 2017, it sparked an entire collecting culture around designer isopods — and Cubaris has been at the centre of that ever since. With 56 species and morphs in this collection, this is our largest and most varied genus page, ranging from genuinely beginner-accessible entry points through to some of the rarest and most expensive isopods available anywhere in the UK.

What unites the genus is their origin. The vast majority of Cubaris in the hobby come from the limestone caves and karst formations of Thailand and Vietnam — dark, humid environments rich in calcium. That background shapes almost everything about their care: they need warmth, consistently high humidity, deep substrate for burrowing, minimal disturbance, and abundant calcium sources, ideally including actual limestone in the enclosure rather than just powdered supplements. They breed slowly compared to Porcellio or Porcellionides, and most need several months to acclimate to a new setup before reproduction begins in earnest. Patience is a genuine requirement with this genus, not just a caveat.

Where to start depends entirely on your experience. If you've never kept isopods before, we'd recommend beginning with something from our Porcellio or Porcellionides collections first — the skills you build managing humidity, substrate, and ventilation on forgiving species will serve you well when you move to Cubaris. If you have some isopod experience and are ready to try the genus, the accessible end of this collection includes the Little Sea Isopod (Cubaris murina) and Murina Glacier — the most forgiving species in the genus — alongside the White Shark, White Side/Penguin, Panda King, and Pak Chong, all of which offer genuine Cubaris appeal without the most demanding care requirements.

The mid-range includes well-established species like the Amber Ducky, Jupiter, Red Panda King, and Pink Panda King — visually striking, with reliable breeding once settled. At the premium end sit the iconic Rubber Ducky and its variants — the species that started it all, still among the most sought-after isopods in the world.
