Powder Blue Isopods and Springtail Culture Combo for Sale
Overview
This is a bundled bioactive starter combo: 15 live Powder Blue Isopods (Porcellionides pruinosus) plus one 8oz live Springtail Culture, shipped together in a single order. Buyers choose between Temperate or Tropical springtails at checkout based on what their enclosure needs.
The Powder Blue portion of this combo comes from a TC INSECTS in-house line traced back to a 2017 mother culture. Accordingly, this is the most established Powder morph in our catalog. The combo itself targets first-time bioactive builders who want both layers of the standard cleanup crew (larger surface-active isopods plus tiny mold-control springtails) without ordering two products separately.
What This Combo Includes
- 15 Powder Blue Isopods. Live Porcellionides pruinosus “Powder Blue” from a TC INSECTS in-house bred line dating to 2017. Surface-active, diurnal, and quick on the substrate, with a dusty cool blue-gray coat over a darker base.
- 1 × 8oz Springtail Culture. Choose Temperate or Tropical at checkout. The 8oz cup contains an active culture with substrate, ready to seed an enclosure or transfer into a dedicated culture container.
- Optional Feed Add-On. A separate checkout option adds 2oz Isopod Feed and 2oz Springtail Feed for supporting the cleanup crew after arrival.
Honest Note on the Blue Color
Powder Blue reads as a subtle cool-toned dusty gray-blue, not a vivid bright blue. Under standard tank lighting and against natural brown substrate, the blue cue can look more like a soft frosted finish than a clear color. Photographs sometimes exaggerate the tone. Buyers who specifically want a high-impact color isopod in this combo style should consider the Powder Orange combo instead, since the warm orange reads more dramatically against dark substrate.
Temperate vs Tropical Springtails: How to Choose
This choice should match the enclosure type, not the keeper’s preference. Match the springtail to what you are building:
- Tropical springtails work best in dart frog vivariums, mourning gecko tanks, day gecko enclosures, and any consistently humid tropical setup. They tolerate higher temperatures and prefer constant moisture.
- Temperate springtails work best in cooler or moderately humid enclosures, including crested gecko tanks, many planted terrariums, and indoor setups that stay around standard room temperature. They handle a wider moisture range.
However, both types overlap well in most bioactive setups. When in doubt, Tropical is the default for most reptile and amphibian bioactive builds because it tolerates the heat and humidity those enclosures usually run at.
Why a Combo Instead of Buying Separately?
- One order, one shipment. First, both live components ship together. As a result, the shipping cost stays lower than splitting into two separate live-animal orders.
- Beginner-friendly quantities. Next, 15 isopods and an 8oz springtail culture is a sensible seeder amount for a small to medium bioactive enclosure. Therefore, the buyer does not need to guess at the right counts.
- Slight bundle discount. Additionally, the combo price comes in slightly lower than buying each component separately.
- Full cleanup crew coverage. Finally, isopods and springtails work at different scales. Isopods handle leaf litter, decaying wood, and larger waste, while springtails handle mold, biofilm, and smaller particles. Therefore, running both gives more complete coverage than either one alone.
Honest Note on the 15-Count Quantity
This combo is a seeder pack, not a working breeding colony from day one. 15 Powder Blue Isopods will take a few months to grow into a clearly visible population, and the early weeks will look quiet. This is normal for any new isopod culture. Keepers who want a productive culture faster, or who are seeding a larger enclosure, should consider a 25 or 50 count Powder Blue Isopods single-product order instead of (or alongside) this combo.
Setting Up the Combo
Both components do best in the same general enclosure conditions, which is part of why they pair well. The setup should give both species what they need without forcing one to compromise.
Substrate and Layout
Use a moisture-retaining substrate like coconut fiber blended with flake soil or decayed hardwood. Then top it with a generous layer of leaf litter and a few pieces of cork bark. In addition, add a moist sphagnum moss pocket in one corner as the humid zone. Both isopods and springtails will use the moss pocket heavily during the first weeks.
Moisture
Aim for a moisture gradient: one side moist with sphagnum or damp substrate, the other side slightly drier with bark and leaf litter. Powder Blue Isopods handle a drier average enclosure than many isopods, but they still need a humid retreat for molting and reproduction. Springtails prefer the moist side. Therefore, the gradient layout suits both at once.
Ventilation
Cross-ventilation matters for the isopod side of this combo. Sealed bins with no airflow tend to develop mite blooms and crash cultures. Therefore, a vented lid with one moist corner outperforms a closed lid at uniform high humidity.
Food
Leaf litter and decaying hardwood (avoid pine and cedar) feed both populations as a base diet. Add small vegetable scraps for the isopods. Springtails will graze on biofilm, mold, and decaying organic matter without much supplemental feeding required. However, a balanced prepared diet like TC INSECTS Isopod Food simplifies feeding and adds calcium support for the isopods.
Releasing the Combo
Open both containers indoors as soon as possible after delivery. Transfer the shipping material directly into the prepared enclosure, since small mancae and springtails often hide in the packing. Place the isopod material near the moist side. Then leave the enclosure mostly undisturbed for the first week so both populations can settle.
Best For
- First bioactive enclosure builds where the keeper wants both cleanup layers in one order
- Naturalistic vivariums where a subtle color cue suits the build better than a bright contrast morph
- Small to medium bioactive setups with dart frogs, mourning geckos, day geckos, or crested geckos
- Planted terrariums where mold control matters as much as larger waste cleanup
- Refresh orders for older bioactive setups where the original cleanup crew has thinned out
Not Best For
- Keepers expecting a vivid bright blue isopod, since the color cue is naturally subtle and dusty
- Large bioactive enclosures (40+ gallons), since 15 isopods is too small a seeder count to populate that volume in a reasonable timeframe
- Fully dry reptile enclosures with no humid retreat, since springtails will not survive and Powder Blue will struggle
- Sealed, no-ventilation tubs, which tend to crash mixed cultures faster than single-species ones
- Keepers wanting a productive feeder culture immediately, since the small starter count is a slow-build colony
Recommended Add-Ons
- TC INSECTS Isopod Food for a calcium-supported diet that helps the isopod population build faster
- TC INSECTS Springtail Feed for boosting the springtail culture, with up to 40% protein and laboratory-grade nutritional yeast
- TC INSECTS Assorted Hardwood Leaf Litter for natural food, hiding cover, and humidity support for both species
- TC INSECTS Ultra Habitat Kit for keepers who do not already have a prepared enclosure ready for the combo

Bioactive Combo FAQs
Exactly what comes in this combo?
15 live Powder Blue Isopods (Porcellionides pruinosus) and one 8oz live Springtail Culture. You choose Temperate or Tropical springtails at checkout. An optional 2oz Isopod Feed + 2oz Springtail Feed add-on is available during checkout.
How blue do Powder Blue isopods actually look?
The color is subtle, not vivid. Powder Blue shows as a cool dusty gray-blue tone over a darker base, more like a soft frosted finish than a bright blue. Under standard tank lighting and against natural brown substrate, the blue cue can be hard to see at a glance. Photographs sometimes exaggerate the tone.
Should I pick Temperate or Tropical springtails?
Tropical springtails are the default choice for most reptile and amphibian bioactive builds because they tolerate the heat and constant humidity those enclosures usually run at. Temperate springtails work better for cooler or moderately humid setups like crested gecko tanks or indoor planted terrariums. When in doubt, choose Tropical.
Is 15 isopods enough to populate a bioactive enclosure?
It is enough to seed a small to medium enclosure, but the early weeks will look quiet while the colony establishes. Generally, expect a few months before the population becomes clearly visible. Keepers seeding a larger enclosure (40+ gallons) should consider adding a 25 or 50 count Powder Blue order alongside this combo.
How is this combo different from the Powder Orange combo?
The combo structure is identical: 15 isopods plus an 8oz springtail culture. The difference is the isopod color. Powder Blue reads as a subtle cool gray-blue, while Powder Orange reads as a warm bright orange. Care for both is the same. Pick based on which color suits your enclosure substrate and lighting.
How long until the cleanup crew is self-sustaining?
Springtails typically reproduce visibly within a few weeks under good conditions. Isopods take longer, usually a few months before the population reaches a clearly visible working size. Stable humidity, leaf litter, calcium, and a varied diet support the timeline.
