Porcellionides Isopods for Sale UK

If you're after the most beginner-friendly, bioactive-ready isopods in the hobby, you've found them. Porcellionides pruinosus - the Powder isopod - is the species most keepers start with, and there's a good reason it stays popular long after you've moved on to fancier genera. It's fast, prolific, genuinely hardy, and comes in enough colour morphs to keep things interesting.

Everything in this collection is the same species. All morphs share identical care requirements and will happily interbreed if housed together, so keep them in separate enclosures if you want your colour lines to stay pure. If you just want a thriving, visually varied cleanup crew, the Rainbow Mix is the obvious choice - and one of our best sellers.

All captive-bred in the UK, dispatched Monday to Thursday by Royal Mail next-day, with a live arrival guarantee and 20% overcount as standard.

The Morphs

• Powder Blue - the original morph that gave the whole line its name, and still the most popular.
• Powder Orange - bright, prolific, and probably the single best first isopod for a new keeper.
• Powder White - clean white morph, effective as a subtle cleanup crew.
• Oreo Crumble - mottled dark-and-cream patterning.
• Orange Dalmatian - orange with dark speckling.
• Rainbow Mix - all the morphs together, for maximum visual variety in a working colony.
• Wild Type Guadeloupe - a natural, unmodified Caribbean locality, for keepers who'd rather their cleanup crew blended into the setup than stood out against it.

Why They're the Default Beginner Isopod

Powders tolerate a wide moisture range, breed fast enough that a starter colony becomes self-sustaining within months, and forgive nearly every mistake a new keeper makes. They're happy at normal UK room temperature with no supplementary heating, and they don't need deep substrate or a carefully engineered humidity gradient the way premium Cubaris do.

They're also one of the most effective cleanup crew species available - fast, numerous, and relentless at processing waste - which is why so many reptile and amphibian keepers use them even when they've no interest in isopods as display animals. Our Powder Orange and Powder Blue care guide covers the husbandry in full.

Frequently Asked Questions

What is the easiest isopod for beginners?
Powder Orange (Porcellionides pruinosus) is the usual answer. It's hardy, prolific, tolerant of a wide moisture range, happy at UK room temperature without heating, and forgiving of the mistakes every new keeper makes. Powder Blue and the Rainbow Mix are equally straightforward.

Are all Powder isopods the same species?
Yes. Powder Blue, Powder Orange, Powder White, Oreo Crumble, Orange Dalmatian and Wild Type are all colour morphs of Porcellionides pruinosus. They share identical care needs and will interbreed freely, so house them separately if you want to keep the colour lines pure.

Do Porcellionides isopods roll into a ball?
No. Like other Porcellionides and Porcellio, they're flat-bodied and rely on speed rather than conglobation. If you want the classic rolling pill-bug behaviour, look at Armadillidium instead.

Can you keep Powder isopods with other isopods?
In a bioactive cleanup crew, yes - Powders are fast and prolific enough to hold their own alongside larger species, and mixing is common in vivariums. For a breeding project, keep them separate: larger Porcellio will outcompete them at feeding time, and you can't track colony numbers in a mixed tub.

How fast do Powder isopods breed?
Fast - among the quickest in the hobby. A starter colony typically becomes visibly self-sustaining within a few months, which is a large part of why they're recommended to beginners. You see results while you're still learning.

Are Powder isopods good as a cleanup crew?
They're one of the best. Fast, numerous, hardy across a wide humidity range, and relentless at processing waste - which makes them the default choice for bioactive reptile and amphibian setups. Pair them with springtails for a complete crew, and see our bearded dragon cleanup crew guide for a worked example.
