Octocore Combo (Series X)
The Octocore Combo combines our Octocore Nest and Octocore Outworld into one complete large-format modular habitat system — designed for rapidly expanding ant colonies ranging from hundreds to several thousands of workers.
As part of the Series X ecosystem, the Octocore Combo delivers maximum expansion potential, advanced colony management, and exceptional long-term durability through our integrated Door Slide Technology™ and fully modular design.
 
The included Octocore Nest features four mould chambers with advanced hydration control, while the spacious Octocore Outworld provides a large foraging arena that encourages natural exploration and feeding behaviour — making it especially rewarding for ant keepers to observe thriving colonies in action.
 
Perfect for serious keepers looking to scale up their setup, the Combo offers a complete modular system at a reduced bundle price compared to purchasing items separately.
Additional lids are available separately and can be bought here.
Key Features
8 modular connection ports for maximum expansion flexibility 
Integrated Door Slide Technology™ on every port for safe colony control and easier maintenance 
Central hydration chamber capable of hydrating all four mould sections simultaneously 
Individual hydration points for creating natural humidity gradients 
Central dry zone ideal for: 
seed storage (perfect for harvester species such as Messor barbarus) 
food storage 
pupae/cocoon storage 
reducing mould risk 
Large-format outworld designed for growing and mature colonies 
Double-lipped escape-resistant lid system 
First lip specifically designed for applying ant barriers 
Oversized lid design for easy cleaning and maintenance 
Large integrated handle for safe lifting and repositioning 
Delivered pre-assembled for straightforward setup (just add your connectors)
Built using durable PETG and premium A2 stainless steel hardware 
Capacity Guide
Approximate recommended colony sizes:
2,000+ Lasius niger workers 
600+ Camponotus ligniperda workers (or similar large Camponotus species) 
Actual capacity may vary depending on species size and colony behaviour.

Assembly Guide
We recommend following our Vertex assembly video, available within the product images, as the assembly method is very similar.
Outworld Assembly
Carefully remove all protective film from acrylic components 
Identify the two longer and two shorter side panels 
Attach the shorter panels to the base first 
Repeat with the longer panels 
Ensure all panels sit flush before tightening screws 
Tighten securely without overtightening 
Once assembled:
Attach the top frame 
Secure the first-lip frame 
Remove protective film from the ventilated acrylic lid 
Attach the second-lip frame and handle 
Place the final lid on top 
Nest Setup
Insert the supplied connectors into the chosen ports 
Secure using the included screws and supplied hex key 
Refer to product images for correct final orientation and assembly confirmation.
Important Note
One hex key is supplied per order, not per individual unit.
Example:
Ordering two nests (or a nest and outworld combo) includes one hex key total. 
 
Why Series X Stands Out:
Door Slide Technology™ — Total Control
Integrated sliding doors allow you to instantly isolate or open sections safely, making expansion and maintenance easier while significantly reducing escape risk.
Bigger Chambers, Better Value
Our chambers are approximately 10–20% larger than many comparable systems, giving colonies more usable space and better long-term value.
PETG Construction — Built for Strength and Longevity
Unlike standard PLA systems, PETG offers:
Improved warp resistance 
Higher temperature tolerance 
Safe cleaning up to 60°C 
Long-term durability for repeated use 
Premium Hardware
We use A2 stainless steel screws as standard — stronger and significantly more rust-resistant than common zinc alternatives.
Smarter Outworld Design
Vertical, space-efficient layout 
Minimal assembly required 
Secure double-lipped lid system 
Easy-access oversized opening for maintenance 
True Modularity
With 8 connection points, you can expand your setup however you choose using:
tubing 
additional nests 
outworlds 
test tube adapters 
Build your setup your way.
Built to Last. Built for Keepers. Built for the Future.
Series X is engineered for decades of use — not seasons.
Less waste.
Greater durability.
Better long-term value.
If you’re looking for reliability, innovation, and professional-grade quality without unnecessary markup, Series X is the future of ant keeping.
