Formicarium Marble S

Staged expansion is the gentlest way to grow a colony. With three latches, Marble S lets you keep a young colony in a small, easy-to-manage space and open the nest a little at a time as numbers build — cleaner, calmer, and far less stressful than dropping a founding colony into a big empty nest.

Marble S suits founding colonies and small, humidity-loving species, and any keeper who likes to manage growth precisely. Start a queen with her first workers and expand step by step.

Smaller space early means a tidier, more humid nest. Marble S is built for that — use the three latches to keep the colony close at first, then open each section as the colony earns it.

Fill the humidity chambers and the gypsum wicks moisture into the surrounding cells, holding an even gradient the colony can choose from. Top up the water every few days; the stone keeps the climate stable with none of the condensation swings of sealed acrylic.

Breathable gypsum plus light airflow keeps the nest fresh. Avoid over-watering, clear leftover food promptly, and leave a waterer empty for a day if a chamber gets too damp.

The fitted lid and arena walls keep workers contained. For tiny or climbing species, a thin band of anti-escape fluid around the arena rim adds extra security.

Marble S arrives clean and ready. Rinse the gypsum, let it take up water, connect a tube if joining an outworld, and populate — no curing, no fuss.

Dress the integrated arena with sand, a stone or some moss to make a tidy foraging space and a display piece. Keep it light so feeding and cleaning stay easy.

Pair Marble S with a drinking dish, protein and carbohydrate jelly, and soft tweezers for clean feeding. A tube connection lets you add an arena or link nests as the colony grows.

Gypsum is sturdy and easy to wipe down. Spot-clean the arena, refresh the water, and don’t force the latches while the colony is active.

Shipped year-round with heat or cool packs and a live-arrival guarantee — DHL across the EU, InPost in Poland, EMS worldwide. Questions on set-up or species fit? The ANTonTOP team keeps ants too and is glad to help.

Open the latches one by one as the colony fills each section. When Marble S itself is full, connect a larger nest or an arena by tube — growth stays gradual and stress-free.

Founding colonies do best in tight quarters — it mimics the small starting chamber a queen digs in the wild. Marble S’s staged latches let you recreate exactly that, then expand as nature would.

What makes Marble S different from Pearl S?
An extra latch — three instead of two — for finer staged expansion control.

Is it good for a founding queen?
Yes — it’s ideal for founding colonies and precise, low-stress growth.

How often do I add water?
Usually every few days; top up the four humidity chambers.

Can I expand later?
Yes — open the latches in stages, then connect a bigger nest or arena by tube.
