Thai Red Springtails: Care Guide
Thai Red Springtails (Lobella sp.) are a large, vivid red tropical springtail kept both as a bioactive cleanup crew and as live food. They want a consistently damp substrate, high humidity of 85-95%, and warmth of 24-28°C, which is warmer than many UK rooms, especially over winter, so a small heat mat on a thermostat keeps them breeding. They are unusually protein-hungry, so sprinkle fish flakes lightly every few days, mist with dechlorinated water, and keep the lid on. They breed more slowly than white springtails but build steadily once settled, and unlike most springtails they don't jump - which makes them far easier to work with.

What Makes Them Different
Thai Reds are detritivores (Collembola), red to reddish-brown, and big and stout for a springtail, easy to see with the naked eye. Like all springtails they feed on decaying plant material, fungi, algae and bacteria, recycling nutrients and keeping an enclosure clean. They're particularly valued for mould control: in a planted terrarium they consume mould and fungus spores before they can spread, and help keep nuisances like fungus gnats in check.
Two things set them apart from the standard white springtail. First, the colour - they're genuinely visible against dark substrate, which most keepers enjoy and which makes it far easier to see whether your culture is thriving. Second, they don't jump. Most springtails use a springing organ called a furcula to launch themselves when disturbed; Thai Reds don't, so you can open the enclosure without them pinging out of it.
Setting Up Their Habitat
Thai Reds want a moist environment rich in organic matter, so a simple tub, terrarium or vivarium with the right substrate makes an ideal home. They like to dig, so give them a deep layer of organic topsoil, at least 3 to 5cm, mixed with coconut fibre and topped with a little sphagnum moss and leaf litter - it holds moisture, provides shelter, and slowly breaks down to feed them. Adding pieces of rotting wood or cork bark gives them hiding places (springtails are shy and like to tuck into crevices) and a slow food source. A secure lid keeps humidity in.
Humidity, Moisture and Temperature
Moisture is the most important factor. Thai Reds need consistently high humidity - around 85-95% - but can be harmed by waterlogging as much as by drying out, so aim for reliably damp, not wet.
- Misting: mist regularly with dechlorinated water - tap water's chlorine can harm them. A hygrometer makes humidity easy to monitor, and a solid lid holds moisture in.
- Temperature: unlike cooler-preferring species, Thai Reds are tropical and do best in warmth, broadly 24-28°C. That is warmer than many UK rooms, especially over winter, and below about 22°C they slow right down, so a low-wattage heat mat on a thermostat, fixed to the side of the tub, keeps a culture productive. Avoid strong heat, which dries them out, and never let standing water stagnate.
Feeding
The substrate itself - leaf litter, rotting wood, coir - feeds them as it breaks down, along with the fungi and bacteria growing on it, but Thai Reds are unusually protein-hungry and a colony builds on regular protein. To supplement, offer:
- Extra dried leaves, bark and rotting wood
- Small amounts of vegetable scraps
- Fish flakes, the reliable favourite, sprinkled lightly every few days, with dried daphnia, a little mushroom or a purpose-made springtail food alongside
Sprinkle food on the substrate surface. The one rule is not to overfeed: excess food quickly goes mouldy and fouls the culture, so offer a little at a time and let them clear it before adding more. For portion sizes and how often to feed, see what springtails eat.
Breeding and Population
Thai Reds breed more slowly than white springtails, so expect a starter culture to take two to three months or more to build to the point where you can split it. Given steady warmth, humidity and regular protein, a healthy culture then maintains itself with little effort, with tiny young appearing throughout the substrate. Their numbers are also self-limiting: when food or space runs short, reproduction naturally slows, so a culture settles at whatever level its conditions support rather than overrunning.

Using Them as a Cleanup Crew
In a bioactive setup, Thai Reds do the work isopods can't. Isopods process leaf litter and larger debris; springtails graze the mould, biofilm and fine organic matter in the top layer of substrate. They occupy different niches and thrive in the same humid conditions, which is why most bioactive enclosures want both. Our guide to building a bioactive cleanup crew covers the pairing.
Key Differences from Common White Springtails
Worth understanding before purchase - Thai Red Springtails aren't a direct substitute for Folsomia candida:
- Size: up to around 5mm and stout-bodied, far easier to see than white springtails at 1-3mm
- Movement: They don't jump. Folsomia candida flicks itself away with the furcula, the spring that gives springtails their name; Thai Reds have no working furcula, so they walk slowly and deliberately
- Breeding rate: Slower than white springtails - colonies take longer to establish
- Care difficulty: They need more warmth and humidity than white springtails and are less forgiving when a culture dries out or runs cold
- Function: Primarily display species rather than workhorse cleanup crew
- Cost: More expensive due to slower breeding
If you want a cleanup crew that establishes fast in a general bioactive setup, white springtails (Folsomia candida) are the quicker option. If you want a specialised display species or supplementary microfauna, Thai Red Springtails are an interesting choice.
What They DON'T Do Well
Honest framing for keepers considering them:
- Not a workhorse cleanup crew - populations too slow-breeding
- Not for beginners - more demanding than standard springtails
- Not for dry setups - demanding high humidity
- Not ideal as primary feeder - too slow to keep up with regular feeding demands
Frequently Asked Questions
How do you care for Thai red springtails?
Keep the substrate consistently damp but not waterlogged, humidity at 85-95%, and temperature at 24-28°C. Feed a little protein such as fish flakes every few days, mist with dechlorinated water, and keep a lid on to hold humidity. Once settled they are steady, but they are less forgiving than white springtails if the culture dries out or gets cold.
Are Thai red springtails warmth-loving?
Yes - they're tropical and prefer 24-28°C, warmer than temperate species like Folsomia candida. Many UK rooms run cooler than that, especially over winter, so a low-wattage heat mat on a thermostat keeps a culture active; below about 22°C they slow right down.
Do Thai red springtails jump?
No. Unlike most springtails, Thai Reds have no functional furcula, so they don't launch themselves when disturbed. That makes them considerably easier to watch, handle and contain than a jumping culture.
What do Thai red springtails eat?
They graze decaying organic matter, mould, fungi and bacteria in the substrate, but they are unusually protein-hungry: fish flakes sprinkled lightly every few days, with dried daphnia or a little mushroom alongside, are what build a colony. Don't overfeed; excess food moulds and fouls the culture.
Can Thai red springtails live with isopods?
Yes - it's a classic bioactive pairing. They occupy different niches (springtails handle mould and microfauna, isopods larger debris) and thrive in the same humid conditions, so they complement each other rather than compete.
Why are my Thai red springtails dying?
Almost always moisture or chlorine. Substrate that's dried out or waterlogged will crash a culture, and untreated tap water can kill them - use dechlorinated water. Overfeeding is the other common cause: excess food moulds and sours the substrate. A culture that runs cold or short of protein stalls rather than dying outright, so check the warmth and the feeding too.
