Formicarium Centre

Moving a colony straight from a tube into a large nest is where a lot of beginners come unstuck: the empty chambers turn into damp, stale pockets a small colony can’t keep clean. The Centre is sized to skip that, small enough to hold humidity where it matters and big enough to grow into for months. It is the natural step up from a test tube and an easy nest for a first-time keeper or a classroom, with clear walls that let you watch the queen, brood piles and every forager without opening anything. When the colony is ready, the 3 mm port takes tubing to an arena or larger home, so growth never means a forced relocation. Fast-growing giants like large Messor barbarus or big Camponotus will use it through founding, then move on to something roomier.

Fill the sponge chamber through the 3 mm port with a syringe once or twice a week and the water spreads by capillary action between the layered sheets, giving a gentle gradient (damp near the sponge, drier toward the arena) so the colony picks the spot that suits its brood. Top the sponge up before it dries completely and never flood it; lightly moist is the goal. Laser-cut micro-perforations keep passive airflow constant, and fresh air plus controlled moisture is your main defence against mold, so clear leftover food promptly.

The Centre arrives clean and ready. Peel the protective film from both faces, connect a tube if you are joining a test tube or outworld, fill the humidity chamber and populate. The fitted lid and arena walls hold workers in; for tiny or climbing species, a thin band of anti-escape fluid around the arena rim adds security.

A drinking dish or feeding plate so food doesn’t spoil into the substrate, protein and carbohydrate jelly for steady nutrition, soft tweezers for brood and food, and a syringe for watering. Tubing connects a larger nest or arena when the colony outgrows the Centre. Dress the small arena lightly: a pinch of sand, a moss stone or a miniature house that clears the 4 cm height.

Is the Centre a good first nest?
Yes — it is made for a young colony’s first move out of the test tube, sized to populate from around 50 workers.

How many ants does it hold?
Around 50–300 workers; the 9 mm chamber height fits most popular beginner species.

How do I water it?
Through the 3 mm port with a syringe, once or twice a week, into the sponge chamber — never flood it.

Can I expand it?
Yes — connect a larger nest or arena by tube when the colony grows, and the ants migrate over on their own.

Does it suit children and classrooms?
With adult setup, yes — the acrylic is solid and the lid is secured; keep small assembly parts away from very young children.

Do you ship outside the EU?
Yes — dispatched in 24 h from Poland with tracked EU and worldwide delivery, year-round with heat or cool packs and a live arrival guarantee.
