Core Strata - Vertical Substrate (XL) Ant Nest/Formicarium

Build your setup your way.....

This modular ant nest combines a natural substrate environment with a precision 3D-printed enclosure, creating a secure and highly functional habitat for digging/tunneling species. The vertical chamber is designed to support natural tunnelling and chamber formation while promoting stable humidity and consistent hydration. A clear acrylic viewing panel allows easy observation of colony growth and underground activity.

🐜 Key Features

• Durable 3D-printed nest regulates humidity and supports brood growth
• Integrated hydration ‘weep’ holes at different heights allows for the creation of a humidity gradient 
• Transparent acrylic front cover provides clear chamber and brood visibility
• Sloping floor and external drain allows for removal of excess water if required
• Weep holes and drain have embedded stainless steel mesh for increased escape prevention
• Rear wall ribs assist in maintaining substrate stability and reduce chances of tunnel collapse
• Universal connection design fits standard tubing (13mm & 16mm O/D) for easy expansion and connection to an outworld 

Suitable Ant Species

Best suited for smaller species that have a preference for tunneling such as Aphaenogaster longiceps (Funnel Ant), Pheidole sp (Big Headed Ant), Iridomyrmex bicknelli (Pavement Ant).

Setup Guide

1. Add suitable substrate (not included) depending on your colony and preferences
2. Hydrate the nest as required
3. Connect suitable tubing depending on ant species (13mm & 16mm O/D) 
4. Introduce the colony by attaching directly to the nest

Hydration Guidelines

• Add water slowly to the hydration area only – 1-2ml at a time
•  Lightly damp, not saturated — avoid standing water
• Rehydrate when the substrate begins to lighten in colour
• Frequency typically every 2–7 days, depending on species, temperature, and humidity needs

Care & Maintenance

• Maintain species-appropriate temperatures and humidity level
