Powder Blue Isopods Size, Appearance and Behaviour
Powder Blue isopods are a small to medium-sized species.
They’ll typically grow up to just over 1cm (around 0.5′) in size, but these little pocket rockets are plenty active. Pop them in and watch them go!
Much like their Porcellionides pruinosus twins, the Powder Orange Isopods, these critters have a dusty texture to their carapace – ranging from pale silver to a darker chrome color.
Powder Blue Isopods are incredibly active feeders and breeders, which makes them a great bioactive choice and an excellent beginner species.
Let’s take a closer look at why.
Pros (and Cons) of Powder Blue Isopods
Porcellionides pruinosus have a great reputation in the industry and continue to be one of the most popular
- Adaptable – Powder Blue Isopods can easily handle most terrarium/vivarium conditions with no issues at all. So you can confidently choose this species for your next project.
- Prolific – Let’s just say these little critters put their energy to good use… They are rapid breeders, and they tend to have large broods, so you’ll have a thriving population in record time.
- Bioactive – These isopods have a voracious appetite, so they make excellent tank custodians. Munching on any decomposing organic material and keeping your enclosure clean and healthy.
In terms of cons, there’s really only one that’s important to note.
- Delicate – Despite their hardy appearance, they’re actually a soft-bodied species. So they’re not the best
isopodspecies for handling. If you’re looking for an isopodpet you can interact with a bit more, you might want to consider something like the Zebra Isopodinstead.
Powder Blue Isopod Care
Habitats – Isolated and/or Bioactive
You can keep Powder Blue Isopods in two ways.
Either in their own culture container or in a larger bioactive terrarium/vivarium – or both!
Even for established terrariums, it’s often a good idea to have a separate culture going as a means to top-up your colony (or as a full backup if something goes wrong).
As medium-sized isopods, you won’t need a huge container for their culture. But they do multiply rapidly, so be prepared to upscale or divide if you start off small.
I always like to recommend at least a shoebox-sized container to start with.
They’ll need plenty of ventilation, so unless you’re running with a dedicated
When it comes to ventilation holes – as with most things – little and often is the best way. You’ll get better airflow with lots of little holes right around the container rather than one big hole.
Terrariums and vivariums often have this built-in with a partial lid or venting system.
However you keep your Powder Blue Isopods, you’ll need a versatile bioactive substrate.
It must be able to retain moisture well (isopods absolutely cannot be allowed to dry out) and have some organic components to feed on.
In an isolated container, you can use a simple mix of coco coir, earthworm castings, and sphagnum moss.
That being said, I swap out some of their materials for more renewable versions (as mentioned in the bioactive substrate article linked above).
On top of the substrate, you’ll always need a layer of sprinkled leaf litter.
This is the easiest way to provide both their natural food and their environmental materials in one go!
Powder Blue Isopods Humidity and Temperature
A big part of what makes Powder Blue Isopods so adaptable is their ability to thrive in a wide range of temperature and humidity levels.
They really don’t need anything fancy here. A typical household temperature range of 70-80°F (21-27°C) is absolutely fine.
Unless you run a cold house… in which case you might want to pop your enclosure in the warmest spot.
Humidity is just as easy to achieve too. Provided you’re using a mostly closed container (which I’d recommend with these little jailbreakers), and you’re keeping the moisture levels up, it should be generating plenty of humidity.
Aim for above 50% for best results.
What do Powder Blue Isopods Eat?
In a bioactive setup, the naturally decaying organic matter (also known as detritus) should form the primary nutrition source, but there’s plenty more they’ll eat.
Powder Blue Isopods eat a diverse range of foods, and they have enormous appetites for their size.
They’ll happily consume just about any supplementary fruit or vegetable cuttings.
So, you can generally give them whatever comes out of the kitchen. Though it’s better to go with small bits at a time so nothing goes to waste and spoils.
Vegetables are also preferable over fruit, as fruit can attract unwanted pests.
In an isolated culture, you’ll probably want to feed them a couple of times a week. But, in an established vivarium ecosystem, they may need a lot less.
They’ll also need protein to stay strong and healthy.
Fish flakes/pellets are a common and convenient choice, but Powder Blue Isopods will reportedly consume all manner of meat scraps too.

Breeding Powder Blue Isopods
Breeding Powder Blue Isopods is as simple as keeping them happy and warm.
Honestly, they’re such prolific breeders. You really just need to meet their basic care requirements, and the rest will take care of itself.
Though they do breed faster at warmer temperatures, so turn up the thermostat a little for a boost!
In a culture, it’ll probably be a matter of weeks, and you can expect an established terrarium colony to easily maintain itself.
