Pixel Yellow A is a high-contrast modular formicarium built around separate humid and dry nest areas. Its black, yellow, and white body components are made from colored PETG, while a partial G23 gypsum insert occupies part of the living space. The resulting layout supports distinct areas for brood and stored food without dividing the colony between separate enclosures.

Colored PETG with a smooth underside

PETG replaces conventional colored acrylic in the main body components. Black, yellow, and white elements produce the characteristic appearance while forming the functional structure of the ant farm. A single solid PETG sheet is used for the bottom, concealing the lower hardware and creating a flat base.

Black nylon bolts and nuts hold the layers together. Nylon does not rust, and the dark hardware integrates with the black parts of the enclosure. With no exposed fastener heads protruding underneath, the formicarium can sit neatly on a desk, shelf, or other furniture surface.

Variant A and its partial gypsum floor

A 6 mm G23 gypsum insert covers only part of the nest rather than extending through every chamber. The gypsum carries moisture in its section, while neighboring spaces retain a smooth plastic floor. This arrangement creates several functional areas:

• a humidified region where the colony can place brood;
• dry chambers for seeds and other food stores;
• four independently arranged humidification zones;
• five sections that can be made available over time.

The separation is particularly useful for harvester ants because their seed stores need distance from excess water. It does not establish one universal husbandry setting. The amount and frequency of watering should be selected for the species, colony population, and observed condition of the nest.

Five sections for gradual expansion

The living area measures 200 × 200 mm and is divided by solid partitions into five individual sections. A small colony can begin with access to a limited area, then receive additional chambers as its population rises. Available nest volume can therefore follow the colony’s stage of development instead of being opened in full from the beginning.

Vertical clearance is 15 mm in chambers above the gypsum layer. The dry sections without gypsum provide 21 mm of height. These measurements are intended to leave room for movement by larger compatible workers and queens as well as smaller colony members.

An 83 mm arena with side access

The arena has an overall height of 83 mm. A sliding door in its side is intended for feeding, waste removal, and other routine care. It provides focused access to the open area, so the complete top does not need to be removed for every minor task.

The behavior and speed of the ants should be considered before opening the door. Once maintenance is complete, make sure the panel is fully closed and that no ants are positioned in the path of the moving part.

A paired transparent cover

Two transparent 3 mm acrylic sheets close the top of the arena. The paired design increases rigidity and helps limit warping associated with moisture. Mechanical latches secure the cover.

Before introducing a colony, inspect the seating of both acrylic sheets, the sliding door, partitions, and all joints. The same points should be checked after feeding or cleaning and before moving the formicarium. The protective components depend on correct assembly, complete closure, and attentive use.

Named genera and species

The source presents Pixel Yellow A for Messor, Pogonomyrmex, Camponotus, and other commonly kept ants. It specifically lists:

• Camponotus japonicus — Japanese carpenter ant, SKU-M-002;
• Camponotus fedtschenkoi — golden desert ant, SKU-M-003;
• Camponotus nicobarensis — reddish carpenter ant, SKU-M-004;
• Camponotus pseudoirritans — Asian ground ant, SKU-M-001.

Before relocation, compare worker and queen size, species-specific moisture requirements, food-storage behavior, and the current colony population with the enclosure’s dimensions. Inclusion in the source list does not replace research into the needs of the particular species.

How the system is organized

Pixel Yellow A combines five living sections with four humidification areas. The partial G23 gypsum insert establishes a moisture-bearing region, while the PETG floor keeps adjacent chambers dry. The arena functions as the feeding and maintenance space, the sliding door gives routine access, and the double acrylic cover with mechanical latches closes the upper opening.

This model is intended for keepers who want to expand nest space gradually and maintain clear functional zoning. The black, yellow, and white color scheme gives the enclosure its visual identity, but the practical focus is the relationship between the gypsum section and the dry plastic chambers.

Questions and answers

What does Variant A mean?
The 6 mm G23 gypsum layer covers only part of the living area. The other chambers retain a PETG floor, allowing humid and dry sections to exist within the same nest.

Is the layout suitable for harvester ants?
Messor and Pogonomyrmex are among the genera identified in the source. The humidified gypsum region can serve brood, while the 21 mm-high dry chambers can hold seed stores. Watering still needs to match the selected species.

Why are two acrylic sheets used for the top?
The paired transparent 3 mm acrylic cover provides greater rigidity and reduces moisture-related deformation. Mechanical latches hold it in place and should be checked after each opening.

How is routine arena care performed?
Food can be introduced and waste removed through the sliding door. Afterward, close the door completely and confirm that the upper latches remain secured.

When should more sections be opened?
Because the nest is divided into five sections, its available area can be increased progressively as the colony grows. The timing should be based on the actual colony population and its use of the current space.
