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 70-80%, and warmth of 21-27°C - normal room temperature suits most UK homes. Feed lightly on leaf litter, spirulina, fish food or a purpose-made springtail food, mist with dechlorinated water, and keep the lid on. They breed prolifically once settled, and unlike most springtails they don't jump - which makes them far easier to work with. Browse our captive-bred Thai Red Springtails for current UK stock.
What Makes Them Different
Thai Reds are tiny detritivores (Collembola), red to reddish-brown, and only a few millimetres long. 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. A mix of coconut fibre, sphagnum moss and leaf litter works well - 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. Springtails need consistently high humidity - around 70-80% - 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 21-27°C. Normal room temperature suits them in most UK homes; only if your room runs cold would a low-wattage heat mat help. Avoid strong heat, which dries them out, and never let standing water stagnate.
Feeding
Feeding is simple, since springtails live on decaying organic matter. The substrate itself - leaf litter, rotting wood, coir - feeds them as it breaks down, along with the fungi and bacteria growing on it. To supplement, offer:
- Extra dried leaves, bark and rotting wood
- Small amounts of vegetable scraps
- A purpose-made springtail food, a pinch of spirulina or fish food, or a few grains of rice - all popular ways to boom a culture
Sprinkle food on the substrate surface, which suits their habit of feeding on top. 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.
Breeding and Population
Thai Reds are prolific breeders, and a healthy culture maintains itself with little effort. Given the right conditions they reproduce rapidly, and you'll see numbers build quickly 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.
Frequently Asked Questions
How do you care for Thai red springtails?
Keep the substrate consistently damp but not waterlogged, humidity at 70-80%, and temperature at 21-27°C. Feed small amounts of springtail food, spirulina, fish food or leaf litter, mist with dechlorinated water, and keep a lid on to hold humidity. They're one of the most forgiving cultures in the hobby.
Are Thai red springtails warmth-loving?
Yes - they're tropical and prefer 21-27°C, warmer than temperate species like Folsomia candida. Normal UK room temperature suits them in most heated homes; a low-wattage heat mat helps only if your room runs cold.
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 handle and to keep in an open-topped setup.
What do Thai red springtails eat?
Decaying organic matter, mould, fungi and bacteria - most of which the substrate provides on its own. Supplement lightly with dried leaves, rotting wood, vegetable scraps, spirulina, fish food or a purpose-made springtail food. 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.
