Pixel White A is an ant habitat with a clean white body, separate dry and humidified areas, and a 200×200 mm nest section. In this version, colored acrylic has been replaced with impact-resistant white PETG, while the solid base is also molded from PETG. The fastening nuts are concealed within the structure, leaving the underside flat. White nylon bolts resist rust and maintain the model’s consistent appearance.

Variant A: moisture only where it is needed

The defining feature of this configuration is the partial layer of high-strength G23 gypsum, 6 mm thick, inside the nest chambers. The gypsum does not cover the entire floor, so the ants can choose between humidified sections and completely dry areas. Brood may be kept close to the moist surface, while seeds and protein stores can remain in chambers with a smooth plastic floor.

This division is particularly useful for harvester ants, including Messor and Pogonomyrmex. The dry compartments separate grain stores from the humidified gypsum and help reduce the risk of moisture-related germination or spoilage. At the same time, the layout does not force the colony into a single microzone: the ants can select suitable areas within the sections currently open to them.

Five sections and four humidification zones

The 200×200 mm nest area is divided into five independent sections. Four separately controlled humidification zones are provided for distributing moisture. Special partitions keep the sections closed, allowing the keeper to expand the colony’s available space gradually instead of exposing the entire nest from the beginning.

Chamber clearance varies according to the floor material:

• 15 mm above the gypsum;
• up to 21 mm in the dry plastic compartments.

This clearance also accommodates larger species and large queens. Partial gypsum coverage, two chamber heights, and a sectional layout form a practical system: moist chambers provide areas where the colony can seek additional humidity, dry chambers serve as storage space, and the partitions support controlled, progressive occupation of the nest.

A tall arena with a sliding access door

The arena has an overall height of 83 mm. A sliding door provides access for feeding and waste removal without requiring the entire upper assembly to be taken off. This makes routine maintenance more direct and can limit disturbance to the colony while food is added or debris is removed.

The arena’s vertical space allows suitable furnishings to be arranged for the species being housed. Decoration and accessible volume should still correspond to the colony’s current size, and unused nest sections should remain closed until expansion is appropriate.

Double transparent lid

The top is fitted with a double lid made from transparent 3 mm acrylic. The paired structure is designed to resist deformation associated with moisture inside the enclosure. Close-fitting mechanical shutters complement the lid and secure the intended openings.

Escape protection depends on several components working together: the double acrylic lid, mechanical shutters, sectional partitions, and accurately assembled body. Every maintenance session should therefore include a check that the sliding door is shut, partitions are correctly installed, and shutters are secured. Before moving the formicarium, confirm that all movable elements are fully closed and handle the unit carefully.

Materials and functional layout

The main white components are made from PETG, including the body and opaque monolithic base. Transparent 3 mm acrylic is used for the double upper lid. A 6 mm layer of G23 gypsum forms the partially humidified floor, while white nylon bolts hold the construction together.

The design combines several functional areas:

• Chambers partially lined with gypsum for humidified zones.
• Dry chambers with smooth plastic floors for stored food.
• Five nest sections that can be opened in sequence.
• Four independent humidification zones.
• An 83 mm-high arena with sliding access.
• A double transparent lid with mechanical shutters.

Suitable ants

The chamber format is intended for Messor, Pogonomyrmex, and larger Camponotus species. The source recommendations specifically list:

• Camponotus japonicus;
• Camponotus fedtschenkoi;
• Camponotus nicobarensis;
• Camponotus pseudoirritans.

Species compatibility does not remove the need to consider the size and current population of an individual colony. A young colony should receive space in stages, with surplus sections kept closed until natural growth calls for expansion. Humidification must likewise follow the needs of the species. Four zones provide flexibility in moisture distribution, but they do not imply that every zone should be operated identically or continuously.

A structured white formicarium

Pixel White A is suited to keepers who want clearly divided humid and dry chambers instead of a continuous gypsum floor. White PETG creates the body and flat base, the transparent lid preserves visibility, and the sectional plan lets the usable nest volume grow with the colony. The result combines a 200×200 mm nest, tall arena, and controlled partial humidification in one enclosure.

Frequently asked questions

What is structurally different about the white version?

White PETG replaces colored acrylic in the main body components. The solid PETG base conceals the fastening nuts and creates a flat underside. The arena now includes a sliding access door, and the white nylon bolts do not rust.

Why is Variant A relevant for harvester ants?

G23 gypsum covers only part of the nest floor. This gives the colony a humidified brood area and separate dry plastic chambers with up to 21 mm of clearance, where grain and protein stores can be kept away from the damp surface.

How does the habitat accommodate colony growth?

The nest is divided into five sections closed by partitions. New rooms can be opened gradually as the colony expands. Four independent zones are available for distributing humidity.

What is the upper lid made from?

It is a double transparent lid made from 3 mm acrylic and supplemented by mechanical shutters. All closures should be checked before feeding, cleaning, or moving the enclosure.
