Angular nest architecture with a controlled moisture gradient

The ANTMART Trigon Black Variant A 200×200 mm is a spacious formicarium built around a distinctive network of triangular chambers. Their many corners and recesses give the colony separate places for arranging brood and stored material, while the black finish emphasizes the internal geometry. Partial gypsum coverage, five nest sections, and two independent hydration zones allow the keeper to expand the usable area gradually and maintain both humid and drier parts of the nest.

The defining Trigon chamber system

Rather than using conventional rounded or rectangular spaces, the residential area is composed of triangular chambers. Their angles create localized niches where ants can gather larvae and cocoons. The clear geometric layout also keeps the interior easy to observe and gives the Trigon series its recognizable visual character.

Available vertical space changes across the nest. Chamber height is 15 mm above the gypsum and 21 mm in areas without gypsum. This additional depth is intended to accommodate larger ants, including Camponotus queens and workers, as they move and tend brood inside the residential zone.

Variant A and partial G23 gypsum

A 6 mm G23 gypsum plate occupies only part of the nest base. The arrangement produces hydrated chambers alongside areas that can remain drier, making it suitable for ants that need to store food away from moisture. Messor is specifically included in the source recommendations because seed reserves can be moved into the non-gypsum sections.

Two independent hydration zones provide further control over how water is distributed through the nest. The appropriate amount and frequency must be selected for the exact species and adjusted according to observed conditions. For ants that require high moisture across the entire residential surface, the source instead points to Variant B with full gypsum coverage.

Five sections for staged expansion

Removable dividers split the residential area into five independent sections. A young colony can begin in a restricted group of chambers, with the remaining sections opened as its population grows. This arrangement helps keep the accessible nest volume proportional to colony size and makes expansion a deliberate process rather than exposing a small family to the complete 200×200 mm layout immediately.

Construction materials

The base is made from PETG plastic, a material that does not absorb water. Clear structural and viewing elements use 3 mm acrylic. Black nylon fittings hold the layers together. Unlike metal hardware, nylon does not rust in a damp environment, so it does not introduce metal corrosion around the moist G23 gypsum.

Key construction details:

• 200×200 mm overall format;
• triangular residential chambers;
• partial 6 mm G23 gypsum coverage;
• 15 mm chamber height above the gypsum;
• 21 mm chamber height in non-gypsum areas;
• five sections with removable dividers;
• two independently hydrated zones;
• an 80 mm-high arena;
• support for a 15 mm test-tube auto-hydration system;
• a double acrylic lid with mechanical sliders;
• a PETG base, 3 mm acrylic, and black nylon fittings.

A rigid double arena lid

The 80 mm arena is covered by two acrylic sheets. Pairing the sheets increases rigidity and helps the cover retain its shape when exposed to humid air. Mechanical sliding locks press the lid against the body and reduce the chance of gaps appearing along the edge. All seams and closures should still be inspected after cleaning, reassembly, or transportation, particularly when the inhabitants are small or persistent explorers.

15 mm test-tube auto-hydration

The model supports an auto-hydration arrangement designed for a 15 mm test tube. It supplies a reserve of water to the hydration system and reduces the need for frequent small manual additions. The input does not state a fixed unattended operating period. Actual duration will vary with the water volume, ambient temperature, evaporation rate, and the moisture regime required by the colony.

Species guidance

The source lists Camponotus nicobarensis, Camponotus pseudoirritans, Camponotus fedtschenkoi, and Messor among the intended inhabitants. The increased chamber height is also discussed in relation to Camponotus japonicus queens. Myrmicaria brunnea and Camponotus maculatus subnudus are mentioned as sensitive species in the context of construction materials. Before relocation, the exact species requirements must be checked and the available nest volume matched to the colony’s current population.

Questions and answers

• What is the purpose of triangular chambers?

The geometry produces additional corners and recesses that ants can use when arranging larvae and cocoons. It also creates a clearly structured nest that remains visually open for observation.

• Why use nylon instead of metal fasteners?

Black nylon does not rust when exposed to water and does not leave metal corrosion products around damp gypsum. It is therefore a practical fitting material for a formicarium with an actively used hydration system.

• Can tropical ants live in this model?

Partial gypsum and two hydration zones make a moisture gradient possible, but compatibility depends on the precise species. If the entire nest must remain consistently humid, Variant B with full gypsum coverage may be the more appropriate layout.

• What makes Variant A suitable for Messor?

The non-gypsum areas provide a drier location for seed reserves while a separate portion of the nest remains hydrated. Conditions in both areas still require regular monitoring and adjustment.
