Running ten founding queens at once? Tube Holder 10 keeps them in line: a rack for 10 test tubes (16 mm) on a steady, anti-tip base, so no tubes roll off the desk and no colonies get tipped over by morning. It also keeps track of which tube holds which queen. Tough plastic that wipes clean and disinfects between colonies, fitting standard ant-keeping and lab tubes. Built for breeders juggling several species.
Bring order to ten founding queens — add one to your bench.
Every ant-keeper starts here. The Test Tube Arena is the simplest complete starter in the range — a 15 mm test tube set inside a compact 5 × 5 × 5 cm acrylic box. The water-charged tube gives a founding queen the humid, enclosed space she needs to raise her first brood; the box adds a small foraging area where you can drop food without disturbing her. An 8 mm or 10 mm port connects it to any modular nest when the colony grows.
New to the hobby? Start right here.
There’s one moment every founding colony reaches: the test tube is full and it needs a proper home. The Centre (14 × 11 cm) is built for exactly that step. Ready to populate from around 50 workers, with a 9 mm chamber for most popular species, a sponge humidity chamber and passive airflow; capacity 50–300. It’s small on purpose — a young colony settles faster and stays cleaner in a nest it can actually fill.

One nest, founding queen to roughly 600 workers — the Ziom earns its popularity by lasting. This compact square acrylic ant nest (13 × 13 × 5.5 cm) covers a colony’s whole early life, with a 9 mm chamber height for most popular species, a sponge humidity chamber, passive micro-perforation airflow, and an interior slider plus exterior security door. Capacity 10–600 workers.

One of Europe’s best-loved acrylic nests, and a true grow-with-you home (20 × 23 × 10 cm). Three independently controlled chambers let you open the nest in stages, dual ports take it further when the colony is ready, and a generous 20 cm arena gives 300–1200 workers a real foraging stage. The 9 mm chamber suits most popular hobby species, from Camponotus to Lasius and Messor. Many keepers raise their first serious colony here, then keep it for years.
Ready for a long-term home? Choose the Comfort.
The Ideal is the most complete nest we build (30 × 32 × 13 cm): four independently controlled sections, three humidity chambers and dual 15 mm ports, sized for an established colony of 500–2,500 workers. The 13 mm chamber height clears larger Camponotus and Messor majors, and you open sections in stages so a big colony is never given more room than it can keep clean. One nest with the control of a professional setup built in.

Most nests come with the chambers cut for you. The DigFix Nest Plate S (23 × 3 × 16 cm) hands that job to the colony — its nest section is packed with firm DigFix sponge substrate the ants tunnel themselves, building a gallery network all their own behind a full-width window. Two 14 mm holes connect a test tube on the nest side and an arena on the foraging side. Built for medium and large digging species. Made in Poland.
Watch a colony dig and build its own home.
Give a digging colony real depth and it builds down. The TerraCore Pro XL runs 7 cm of DigFix substrate, more than double the Pro’s 3 cm, so the ants excavate deeper tunnels and proper multi-level chambers, with room to keep developing for years. A wider 26 × 13 × 9.5 cm arena handles the foraging of a bigger colony. Self-contained 26 × 12 × 20 cm acrylic, universal 14 mm port, capacity ~400–800 ants, beginner-friendly, made in Poland.
More depth to dig, more nest to watch take shape.
A good nest doesn’t have to be big. The Diamond (10 × 9 × 5 cm) is our most popular gift formicarium — a tidy, self-contained home for a small or young colony of 50–150 workers that fits any desk or shelf. Laser-cut 3 mm acrylic, a 9 mm chamber for most popular species, one sponge humidity chamber, passive airflow and a slider door. A handful of ants can keep a small nest cleaner and more humid than an oversized one.

If you keep ants to watch them, viewing quality is everything. The Crystal (20 × 13 × 10 cm) is built around one priority — high-clarity transparent walls that show every gallery, worker and brood cluster in fine detail. Tall 16 mm chambers suit medium-to-large species from Camponotus to Messor harvesters, and the 400–1200 capacity means a maturing colony grows into it. As much a living display as a home.
Want the clearest view? Bring home the Crystal.
Big workers need height, and a big foraging force needs floor space. The Giant L (25 × 12 × 15 cm) gives both: 16 mm chambers that clear large Camponotus and Messor majors, plus an XXL 25 × 12 × 8 cm arena where a colony of 1,000–1,800 workers can run organised trails. This is the nest you move a thriving colony into once it has earned the room, and feeding a society this size is something to see.
Colony outgrowing everything? Order the Giant L.
Separating the feeding area from the nest is one of the simplest ways to keep a colony healthy, and the Modular Arena 10×10 cm makes it easy. This clear acrylic outworld pairs with any 10×10 nest for small-to-medium colonies. Four lockable nut-and-screw entrances, a single 8 mm port and micro-perforation keep it airy and escape-resistant. 10×10×10 cm, made in Poland.
Give the colony room to roam. Add your Modular Arena 10×10.
When a colony hits a few hundred workers, the queue at the nest entrance gets busy. The Modular Arena 20×10 cm, sized for 400 to 800 workers, opens up a clear acrylic place to forage and feed. Six lockable nut-and-screw entrances and a 10 mm port pair it with 20×10 nests; micro-perforation keeps it airy and escape-resistant. 20×10×10 cm, made in Poland.
Give the colony room to roam. Add your Modular Arena 20×10.
Built to crown the 20×20 Matrix and Helix nests, the Modular Arena 20×20 cm gives an established colony of 800 to 1300+ workers a clear acrylic place to hunt and feed. Eight lockable nut-and-screw entrances and a 10 mm port drop it into your setup; laser-cut micro-perforation keeps it airy and escape-resistant. 20×20×12 cm, made in Poland.

Buy one module today and build a whole system later. That is the idea behind the Modular Nest Nebula (10 × 10 cm). A wide central gallery splits into two side corridors, a branching path small-to-medium colonies of up to ~350 workers adopt fast. Lockable nut-and-screw entrances, a sponge humidity chamber and standard ports slot it straight into a growing setup. Fits Lasius, Tetramorium, Messor and most popular species; 9 mm chamber height.
Build the colony’s home module by module. Order your Nebula today.
A square grid of rooms gives the colony clean lines to organise from day one: brood here, food stores there, quarters apart. The Quad 10×10 cm suits the orderly, zone-keeping species especially well. Lockable nut-and-screw ports, a sponge chamber and 9 mm rooms hold up to ~350 Lasius, Tetramorium, Messor or smaller Camponotus, with a 20×10 version for when it outgrows this one.
A tidy, organised home from day one.
When shelf space is the constraint, the Prism 10×10 cm wins on density: tightly packed chambers cram an unusually generous amount of nest into the smallest footprint, and the close walls trap a steadier warmth and humidity. Lockable nut-and-screw ports, a sponge chamber and 9 mm rooms suit up to ~350 Lasius, Tetramorium, Messor or smaller Camponotus.
Maximum nest, minimum shelf space.
Run the corridors on a diagonal and you fit the longest connected path a 10×10 footprint allows. That’s the Nova 10×10 cm: more usable run than a straight grid the same size, so a founding colony settles it evenly from the start. Lockable nut-and-screw ports, a sponge chamber and 9 mm rooms suit up to ~350 Lasius, Tetramorium, Messor or smaller Camponotus.
Start small, grow module by module.
Ants don’t want every room the same — some dark and enclosed for brood, others open for traffic. The Quartz 10×10 cm gives them that with offset, asymmetric chambers instead of a uniform grid, so the colony gives each little space its own job. Lockable nut-and-screw ports, a sponge chamber and 9 mm rooms suit up to ~350 Lasius, Tetramorium, Messor or smaller Camponotus.
Varied rooms a colony actually uses differently.
Four arms of chambers meet at one junction, so nothing in the Pulsar 10×10 cm sits more than a short hop from the centre, so traffic stays quick and brood care stays efficient. Lockable nut-and-screw ports (one per arm), a sponge chamber and 9 mm rooms suit up to ~350 Lasius, Tetramorium, Messor or smaller Camponotus, and it links into a growing modular setup.
Short routes, busy colony, easy to watch.
Year-round shipping across Europe and the UK

Formicarium types — 6 material lines for sale
Acrylic formicaria — lightweight, fully transparent, non-porous. Best for tropical and dry-climate species (Cataglyphis, Messor, desert Camponotus). 23 acrylic models, single-tube starter to multi-chamber blocks.
Gypsum formicaria — absorbent walls hold humidity naturally without misting. Best for beginners, tropical species, and species that like a stable humid microclimate. The most beginner-tolerant build.
Ytong (aerated concrete) formicaria — porous, mineral, breathable. Good middle ground for European species and most genera with moderate humidity needs.
Wooden formicaria — natural look, excellent insulation, ideal for arboreal and wood-loving species (Crematogaster, some Polyrhachis, Camponotus ligniperda).
Cork formicaria — natural cork bark inserts in a sealed outer chamber. Aesthetic display option with a forest-floor feel. Limited models.
Digfix formicaria — natural excavation substrate; the ants build their own tunnels. Ideal for soil-nesting species (Lasius, Formica, Myrmica, Messor) where natural excavation behaviour matters.
Unique / mix formicaria — aquarium conversions, ponerine-specific setups, and one-of-a-kind ant farm concepts for keepers who want something different.
Standalone components
Nests (modular) — just the nest block, no built-in arena. Connect to any standard ANTonTOP arena via 16 mm tubing as the colony outgrows the first chamber.
Arenas and Terrariums — dedicated foraging spaces (outworlds). S to XL sizes to match any colony scale.
Tube holders — test tube stands for founding queens and small colonies before they move into a proper nest.
How to choose your first formicarium
For founding queens (under 30 workers): a test tube nest is enough. Move into a small formicarium once the first 15-20 workers are out and brood no longer fits.
For small colonies (30 to 200 workers): an S or M acrylic or gypsum nest paired with a small arena. Most beginners stay here for 6 to 12 months.
For mid colonies (200 to 800 workers): an L multi-chamber nest. Switch to a digfix or wooden build if the species naturally excavates.
For mature display colonies (800+ workers): an XL multi-chamber block plus a large arena. Camponotus singularis, Myrmecocystus repletes, and Polyrhachis dives shine in large transparent acrylic builds.

Frequently asked questions about formicaria
What is the best formicarium for beginners?
A small gypsum or acrylic nest paired with a small arena. Gypsum is the most forgiving for humidity, acrylic the easiest to clean. Match the choice to your species — dry-climate ants in acrylic, beginners with humidity-loving species in gypsum.
Acrylic, gypsum, ytong or wooden — which build is best?
Acrylic gives the clearest view and easiest cleaning; gypsum holds humidity naturally; ytong is breathable for moderate-humidity species; wooden insulates and suits arboreal genera. Pick by species, not by aesthetics alone.
How do I control humidity in a formicarium?
Gypsum and digfix builds absorb water and hold humidity for days. Acrylic and ytong need a wet sponge or syringe misting on one side. Aim for 40-60 % in the nest and 60-80 % in the arena for most species.
Do you ship formicaria with the queen ant?
Formicaria are sold separately from live colonies. To buy a formicarium paired with a queen, browse our Kits section — full setups with the colony already inside.
How long does delivery take?
1 to 2 business days inside Poland via InPost. 2 to 3 days to Germany, France, Netherlands, Belgium via DHL. 3 to 5 days to other EU countries. 4 to 7 days to the United Kingdom via DHL.
Can I expand a formicarium later?
Yes. All our nests use a standard 16 mm tubing connector, so you can chain additional chambers, attach a larger arena, or connect a second nest as the colony outgrows the first.
What's the difference between a nest and an arena?
The nest is where the queen and brood live, protected from light and disturbance. The arena (outworld) is the open foraging area where workers eat, drink, and explore. A complete setup has both connected via tubing.
Does a formicarium need cleaning?
The arena gets cleaned weekly (remove dead food, dead workers, empty seed husks). The nest itself is rarely cleaned — the workers handle inside hygiene. Wipe outer acrylic walls with a microfibre cloth if dusty.
Is the formicarium escape-proof?
Yes when set up properly. The nest seal is airtight at the connection ports. The arena rim is treated with talc or Fluon (sold in Accessories) to prevent climb-outs.
What size formicarium should I get for my colony?
Match it to colony stage: under 30 workers — test tube. 30 to 200 — S/M nest. 200 to 800 — L multi-chamber. 800+ — XL display block. Over-sized nests can stress small founding colonies, so start small and expand.
