Another collector’s springtail rather than a cleanup crew. Rambutanura sp. from Vietnam is a rare, spiny, non-jumping species kept for how unusual it looks (the same specialist tier as the Red Thai Spiky, from a different locality). Slow to establish, particular about its food, and genuinely uncommon in the hobby.
Two honest notes up front:
- This is a display animal, not a workhorse. It grazes on slime mold, so it won’t do the mold-and-waste cleanup that a standard culture does. Keep it because it’s strange and beautiful.
- The genus is real; the species is undescribed. We list it honestly as Rambutanura sp. rather than inventing a species name.
What You’re Buying
A live culture: a starter population, not a headcount of individuals. Springtails are sold as a culture because the culture is the unit that establishes and reproduces.
This is an advanced springtail: slow, specific about its diet, and uncommon in the US. It suits an experienced keeper who wants a display culture, not a beginner looking for vivarium cleanup.
Keeping Them
- Very high humidity (85–95%): a wet-loving tropical species; keep the medium consistently damp, not merely humid, but never flooded.
- A specialist diet: like its Thai cousin, this Rambutanura grazes on slime mold rather than general mold and detritus. It will not reliably clear vivarium film mold the way a workhorse culture does.
- Stability: a stable, warm, undisturbed culture; it doesn’t recover from swings like a hardy species.
- Charcoal or a moisture-retentive substrate base, as with any culture.
The universal culture mechanics are in the springtail culture guide. Just note the feeding difference above; this species does not eat like the workhorse types that guide is written around.
Vietnam Spiky vs the Others
For a springtail that actually cleans and controls mold, this is not it. Reach for Tropical White (the workhorse) or Orange. The Vietnam Spiky is a display/collector culture, alongside the Red Thai Spiky. New to all this? Start with the bioactive terrarium guide.
Frequently Asked Questions
Will they clean my terrarium or eat mold?
Not reliably. They graze on slime mold, not the general film mold and waste a workhorse culture handles. Keep them for the look; run Tropical White for cleanup.
Do they jump?
No, this species doesn’t have a working spring, so it crawls rather than jumps, which is part of what makes it a good display culture.
How is it different from the Red Thai Spiky?
They’re close relatives: both spiny, non-jumping Rambutanura, from different localities (Vietnam vs Thailand). Both are specialist display cultures, not cleanup crews.
Can I keep them with other springtails or isopods?
Keep the culture on its own. Mixing cultures lets a hardier species out-compete this slow specialist, and you lose the animal you paid for.
How many do I get?
A starter culture sized to establish. Details show on the variant when these go on sale. Join the waitlist to hear first.
