Building a lush, living, bioactive vivarium doesn’t need to drain your wallet — unless you let it. The UK dart frog hobby has its share of pricey gear and boutique moss blends, but you don’t need a sponsored YouTube channel to grow a jungle.
Here’s how I’ve built successful, long-term dart frog enclosures for under £150 — using real products available in the UK, no fluff.
Why Bioactive?
A proper bioactive vivarium runs on a little ecosystem. Springtails, isopods, worms, plants, frogs — all keeping each other in check. Less cleaning, happier frogs, better display.
But bioactive doesn’t have to mean overcomplicated or expensive.
The Cheapest Vivarium That Still Works
Skip the fancy arboreal setups if you’re on a tight budget. Start with a 45x45x45cm Exo Terra or similar. You can often find these second-hand on Facebook Marketplace or Gumtree for £30–£50.
If new, try:
Avoid faunariums or fish tanks — they’re either unsealed or hard to ventilate correctly.
Drainage Layer: Foam Over Balls
Everyone bangs on about LECA or hydroballs, but 25ppi filter foam is where it’s at.
Why?
- Structural support — holds its shape over years
- Inert — won’t break down or leach nasties
- Microfauna friendly — springtails and isopods love it
- Easy to cut to size and fit around hardscape
You can buy it in sheets online or from aquarium supply stores. Get black or dark grey if you can — it blends better.
Top with moss mesh or shade netting to keep the substrate out.
Substrate: Do You Need ABG Mix?
Nope. You can make a solid DIY version that works for UK dart frogs:
DIY Mix:
- 2 parts coco fibre
- 1 part orchid bark
- 1 part topsoil (no additives)
- Handful of leaf litter
Toss in some charcoal or crushed lava rock to boost aeration.
OR buy a ready mix:
Plants That Survive Neglect (and Frogs)
Buy plants once, propagate forever. Look out for:
- Pothos (Epipremnum aureum)
- Tradescantia
- Peperomia
- Ferns (button, Boston)
- Fittonia
- Creeping fig (Ficus pumila)
Try garden centres before going online. You’ll often find pothos cuttings for pennies.

Leaf Litter: You Don’t Need to Import from Peru
Dried oak, magnolia, and beech leaves work perfectly.
Collect from clean, pesticide-free UK woodland, dry them out completely, freeze for 72 hours (to kill pests).

Clean-Up Crew Without the Hefty Price Tag
You don’t need a dozen species.
Essentials:
- Springtails – culture your own in cheap Tupperware
- Isopods (dwarf whites or tropical greys) – get a starter culture and let them multiply
Avoid expensive rare morphs. They’re cool, but not essential.
Starter kits:
- Springtails & Isopods – UK cultures
Lighting: Skip the “Amphibian Specialist” Tax
Use a 6500K LED desk light or budget aquarium LED strip. Mount securely. That’s it.
No UVB needed for most dart frogs.
Heating: Do You Even Need It?
If your room stays above 18°C in winter, you’re good. Otherwise:
- Heat mat (on side, not bottom)
- Controlled with a thermostat
Basic UK setups can run entirely room-temp with no issues.
Misting Systems vs Manual
A £100+ misting system is nice but not vital.
Get a £5 pressure sprayer from Wilko or B&Q and give it a go. Some keepers automate later — most don’t bother.
Total Cost Breakdown (Approximate, UK prices):
| Item | Cost |
|---|---|
| Used Exo Terra | £40 |
| Filter foam + mesh | £10 |
| DIY substrate mix | £10 |
| Plants (local + plugs) | £15 |
| Leaf litter | £5 |
| Springtails & isopods | £15 |
| LED lighting | £12 |
| Misting bottle | £5 |
| Total | £112 |
You’ll spend a little more upfront if you buy everything new, but even then, staying under £150 is very doable.
