ANTMART Flow White 220×110, Variant A is a partially plaster-based formicarium with a white gloss body, transparent viewing surfaces, and triangular geometry. Its structure combines a nest module, a tall arena, and chambers that can be opened in stages, supporting close observation while allowing the available living area to expand as the colony grows.

A white background and distinctive geometry

The Flow White Edition combines layered white and transparent acrylic panels measuring 3 mm thick with PETG plastic components. The white base provides a contrasting background against which ants, brood, larval feeding, and dirt in visible chambers are easier to notice. Its gloss finish and Organic Flow passage design with smooth transitions are paired with a triangular layout that distinguishes Variant A from conventional rectangular arrangements.

The body measures 220×110 mm. Placement should account not only for that footprint but also for the room required to open the arena, service the humidification area, and operate the removable dividers. The model supports observation and gradual occupation, although the chamber system must still be matched to the species and size of the intended colony.

Acrylic, PETG, and non-metallic fasteners

White nylon bolts are used throughout the joints, and the structure contains no metallic fasteners. This is particularly relevant around the moist plaster area, where ordinary metal could oxidize and leave corrosion products or visible staining. Nylon does not rust when exposed to water and helps the joints retain their neutral white appearance.

The formicarium is not made entirely from plaster. Plaster forms a functional section of the nest floor, while the principal body components use acrylic and PETG. This combination provides transparent observation panels, rigid enclosure walls, and a dedicated area through which a humidity gradient can develop across the living chambers.

Zoned hydration with G-23 plaster

Variant A contains a 6 mm slab of high-strength G-23 dental plaster in the residential nest area. Because the slab covers only part of the floor, not every chamber receives the same amount of moisture. The colony can move brood closer to the humidified area and keep stores in a drier section when such distribution suits the biology of the species.

Partial hydration is useful for ants that require moist areas for eggs and larvae while also needing dry storage chambers. Messor is specifically mentioned in the source: a dry section can help reduce the chance that stored seeds will germinate. The actual watering schedule and moisture level must nevertheless be selected for the colony rather than inferred from the formicarium design alone.

G-23 is described as a strong plaster that resists being chewed by ants. The 6 mm slab maintains the shape of the residential area and distributes water through capillary action. The plaster condition and chamber moisture still require visual monitoring; a zoned system does not eliminate routine maintenance.

An 80 mm-high arena

The above-ground functional area is 80 mm high. It provides space for feeding, a water or syrup feeder, and regular colony care. The added height gives the keeper working clearance over the arena floor, although every maintenance action must still account for the speed and body size of the species housed inside.

The arena lid consists of two acrylic sheets. This arrangement increases the rigidity of the upper panel and is intended to reduce warping caused by differences in humidity or temperature between the inside and outside. Mechanical sliding locks hold the edges of the lid against the body.

The double panel and locks form a barrier against gaps and accidental opening. Even so, the lid fit, lock position, and the size of all ventilation or service openings should be checked before occupation and after every maintenance session. These design features assist with escape prevention but do not replace inspection by the keeper.

Two sections for a growing colony

Removable dividers split the nest into two sections that can be opened independently. A small colony can initially receive access to only part of the chamber system rather than being placed in excessive unused space. As worker numbers increase, the divider can be removed to make the next residential section available.

This arrangement supports staged occupation and helps align accessible nest volume with colony development. Before expansion, the keeper should confirm that the existing section is being used and that the new area is clean and has a suitable moisture level. The removable divider is a zoning tool, not an automatic regulator of population size.

Compatibility and practical limits

The source identifies the model as suitable for Messor, Camponotus, active Pogonomyrmex, and many other ants. Chambers are up to 21 mm high, providing clearance for larger workers and queens when the remaining dimensions are appropriate for the species. “Versatile” should not be interpreted as compatible with every colony: the smallest worker size, humidity requirements, ability to chew materials, population, and growth rate must all be considered.

A colony that outgrows the 220×110 mm format will require a larger system. Before occupation, the keeper should also determine whether a partially plaster-based nest is suitable for the selected species and whether its required humidity gradient can be maintained safely.

Questions and answers

1. What is the purpose of the white body?
It provides a contrasting background for observing workers and brood and makes dirt easier to notice. It is a visual feature, not a separate source of illumination.

2. Why are the bolts made from nylon?
Nylon fasteners do not rust beside the moist plaster slab and do not create typical corrosion stains. No metallic joints are used in the structure.

3. How does partial hydration work?
The 6 mm G-23 plaster slab occupies only part of the nest floor. This creates relatively moist and relatively dry areas within the chamber system.

4. Why are there two nest sections?
Removable dividers allow a small area to be opened first. Additional living space can then be released as the colony becomes larger.

5. What secures the arena?
The 80 mm-high arena is covered by a lid made from two acrylic sheets. Mechanical sliding locks hold its edges against the enclosure body, and their position must be checked manually before use.
